内蒙古贷岱海湖现代三角洲沉积考察
一、本文概述
Overview of this article
本文旨在通过对内蒙古岱海湖现代三角洲沉积的详细考察,探讨湖泊辫状河三角洲的岩相、层序特征以及储层地质模型。

岱海湖作为典型的内陆湖泊,其三角洲沉积记录了丰富的地质信息,对于理解湖泊沉积环境、河流-湖泊相互作用以及资源勘探具有重要意义。

本文将结合实地考察资料、前人研究成果以及地质学、沉积学等相关理论,对岱海湖现代三角洲的沉积特征进行深入分析,以期构建一套适用于该区域的储层地质模型,为后续的油气等资源勘探和开发提供科学依据。

This article aims to explore the lithofacies, sequence characteristics, and reservoir geological models of the braided river delta in Daihai Lake, Inner Mongolia, through a detailed investigation of modern delta sedimentation. As a typical inland lake, Daihai Lake's delta sedimentation records rich geological information, which is of great significance for
understanding the lake sedimentary environment, river lake interactions, and resource exploration. This article will combine field investigation data, previous research results, and relevant theories such as geology and sedimentology to conduct an in-depth analysis of the sedimentary characteristics of the modern delta of Daihai Lake, in order to construct a reservoir geological model suitable for the region and provide scientific basis for subsequent exploration and development of oil and gas resources.
在考察过程中,我们将重点关注三角洲的沉积相带划分、沉积序列的时空演化以及沉积物的粒度、成分、结构等特征。

通过对不同相带沉积物的对比分析,揭示三角洲沉积过程中水动力条件、物源供给以及沉积环境等因素的变化规律。

同时,结合区域地质背景,探讨三角洲沉积与区域构造运动、气候变化等因素的关联性。

During the investigation process, we will focus on the division of sedimentary facies zones in the delta, the spatiotemporal evolution of sedimentary sequences, and the characteristics of sediment grain size, composition, and structure. By comparing and analyzing sediments from different
facies zones, the changes in hydrodynamic conditions, material supply, and sedimentary environment during the sedimentation process of delta are revealed. Meanwhile, based on the regional geological background, explore the correlation between delta sedimentation and regional tectonic movements, climate change, and other factors.
在储层地质模型构建方面,我们将综合考虑沉积相带展布、储层物性特征、成岩作用等因素,运用地质统计学方法和三维建模技术,建立一套既能反映三角洲沉积特征又能指导油气勘探的储层地质模型。

该模型将为评价储层质量、预测储层分布以及优化勘探部署提供重要依据。

In terms of constructing reservoir geological models, we will comprehensively consider factors such as sedimentary facies distribution, reservoir physical characteristics, and diagenesis, and use geostatistical methods and 3D modeling techniques to establish a reservoir geological model that can reflect delta sedimentary characteristics and guide oil and gas exploration. This model will provide important basis for evaluating reservoir quality, predicting reservoir
distribution, and optimizing exploration deployment.
本文的研究不仅有助于深化对湖泊辫状河三角洲沉积特征的认识,还将为类似地区的资源勘探和开发提供有益的借鉴和参考。

通过本文的研究,我们期望能够为地质学、沉积学以及相关领域的发展做出一定的贡献。

The research in this article not only helps to deepen the understanding of the sedimentary characteristics of lake braided river delta, but also provides useful reference and guidance for resource exploration and development in similar areas. Through this study, we hope to make certain contributions to the development of geology, sedimentology, and related fields.
二、研究区域地质背景
Geological background of the research area
研究区域位于内蒙古自治区的贷岱海湖地区,是一个典型的湖泊辫状河三角洲沉积环境。

贷岱海湖是一个内陆淡水湖泊,位于华北板块北缘,处于大兴安岭与阴山山脉之间的沉降盆地中。

该区域的气候类型属于温带大陆性气候,四季分明,降水主要集中在夏季。

The research area is located in the Dai Dai Lake area of Inner Mongolia Autonomous Region, which is a typical braided river delta sedimentary environment. Daidaihai Lake is an inland freshwater lake located on the northern edge of the North China Plate, in a subsidence basin between the Great Xing'an Mountains and the Yinshan Mountains. The climate type in this region belongs to temperate continental climate, with distinct four seasons and precipitation mainly concentrated in summer.
贷岱海湖地区的地层主要由第四纪松散沉积物组成,其中包含了丰富的湖泊、河流和三角洲沉积序列。

这些沉积物主要由河流携带的陆源碎屑物质组成,包括砂、粉砂、粘土等。

湖泊辫状河三角洲是该区域的主要沉积类型之一,其形成和发展受到区域构造运动、气候变化和河流作用等多种因素的控制。

The strata in the Daihai Lake area are mainly composed of Quaternary loose sediments, which contain rich sedimentary sequences of lakes, rivers, and deltas. These sediments are mainly composed of terrestrial debris carried by rivers, including sand, silt, clay, etc. Lake braided river delta is one of the main sedimentary types in the region, and its
formation and development are controlled by various factors such as regional tectonic movement, climate change, and river action.
湖泊辫状河三角洲的形成通常与河流的冲刷和填积作用密切相关。

在河流进入湖泊的过程中,由于水流的扩散和沉积物的堆积,形成了独特的辫状河三角洲结构。

这些辫状河三角洲通常具有复杂的地貌特征和沉积序列,包括分流河道、天然堤、沼泽、湖泊等多种沉积环境。

The formation of braided river deltas in lakes is usually closely related to the erosion and filling of rivers. During the process of rivers entering lakes, a unique braided river delta structure is formed due to the diffusion of water flow and the accumulation of sediment. These braided river deltas typically have complex geomorphic features and sedimentary sequences, including distributary channels, natural embankments, swamps, lakes, and other sedimentary environments.
在贷岱海湖地区,湖泊辫状河三角洲的沉积序列记录了该地区长期以来的气候变化和河流作用历史。

通过对这些沉积序列的详细研究,
可以深入了解该区域的古气候、古环境以及沉积作用过程,为储层地质模型的建立提供重要的基础资料。

In the Dai Dai Lake area, the sedimentary sequence of the lake braided river delta records the long-term history of climate change and river action in the region. By studying these sedimentary sequences in detail, we can gain a deeper understanding of the paleoclimate, paleoenvironment, and sedimentary processes in the region, providing important basic data for the establishment of reservoir geological models.
贷岱海湖地区的湖泊辫状河三角洲沉积环境具有独特的地质背
景和沉积特征。

对这些特征进行深入研究,有助于揭示该区域的沉积演化历史和油气储层特征,为后续的油气勘探和开发提供重要的科学依据。

The braided river delta sedimentary environment in the Dai Dai Lake area has a unique geological background and sedimentary characteristics. Conducting in-depth research on these features helps to reveal the sedimentary evolution history and oil and gas reservoir characteristics of the region, providing important scientific basis for subsequent oil and gas
exploration and development.
三、湖泊辫状河三角洲岩相特征
Lithological characteristics of lake braided river delta
湖泊辫状河三角洲是湖泊环境中一种特殊的沉积体系,其岩相特征独特,既包含了河流沉积的特征,又体现了湖泊环境的影响。

通过对内蒙古岱海湖现代三角洲的详细考察,我们可以揭示其岩相特征及其形成机制。

Lake braided river delta is a special sedimentary system in the lake environment, with unique lithological characteristics that not only include the characteristics of river sedimentation, but also reflect the influence of the lake environment. Through a detailed investigation of the modern delta of Daihai Lake in Inner Mongolia, we can reveal its lithological characteristics and formation mechanism.
湖泊辫状河三角洲的岩相主要由砂砾岩、砂岩和泥岩组成,其中砂砾岩和砂岩占据主导地位。

砂砾岩主要由砾石和砂粒组成,砾石多呈次棱角状,分选性差,反映了辫状河沉积中快速堆积的特点。

砂岩
则多呈中细粒结构,层理清晰,多发育平行层理和交错层理,反映了水流对砂粒的搬运和沉积作用。

The lithology of lake braided river delta is mainly composed of conglomerate, sandstone, and mudstone, with conglomerate and sandstone dominating. Sandstone is mainly composed of gravel and sand particles, and the gravel is mostly in a sub angular shape with poor sorting, reflecting the characteristics of rapid accumulation in braided river sedimentation. Sandstone, on the other hand, is mostly of medium to fine grain structure, with clear bedding and
well-developed parallel and cross bedding, reflecting the transport and sedimentation of sand particles by water flow.
在湖泊辫状河三角洲中,泥岩也是重要的组成部分,它多呈条带状或不规则状分布在砂岩和砂砾岩之间,构成了三角洲沉积的重要分隔层。

泥岩的颜色多变,从深灰色到黑色不等,反映了湖泊沉积环境的还原性质。

In braided river deltas of lakes, mudstone is also an important component. It is mostly distributed in strip or irregular shapes between sandstone and conglomerate, forming
an important dividing layer of delta sedimentation. The color of mudstone varies from dark gray to black, reflecting the reducing properties of the lake sedimentary environment.
湖泊辫状河三角洲中还发育有大量的沼泽沉积,这些沼泽沉积主要由炭质泥岩和煤组成,它们呈条带状或不规则状分布在三角洲平原地区,是三角洲沉积体系中的重要组成部分。

In the braided river delta of lakes, there are also a large number of swamp sediments, which are mainly composed of carbonaceous mudstone and coal. They are distributed in strip or irregular shapes in the delta plain area and are an important component of the delta sedimentary system.
湖泊辫状河三角洲的岩相特征主要表现为砂砾岩、砂岩和泥岩的交互沉积,以及沼泽沉积的广泛发育。

这些岩相特征的形成与辫状河的水流特征、湖泊的水动力条件以及三角洲平原的地形地貌密切相关。

通过对这些岩相特征的研究,我们可以深入理解湖泊辫状河三角洲的沉积机制和演化历史。

The lithological characteristics of braided river deltas in lakes are mainly characterized by the interactive sedimentation of sand conglomerates, sandstones, and mudstones,
as well as the widespread development of swamp sediments. The formation of these lithofacies features is closely related to the flow characteristics of braided rivers, the hydrodynamic conditions of lakes, and the topography and geomorphology of delta plains. By studying these lithological features, we can gain a deeper understanding of the sedimentary mechanisms and evolutionary history of lake braided river deltas.
四、湖泊辫状河三角洲层序特征
Sequence characteristics of lake braided river delta
湖泊辫状河三角洲的层序特征主要表现为其独特的沉积序列和
层序结构。

通过对内蒙古贷岱海湖现代三角洲的详细考察,我们可以观察到一系列清晰的层序特征,这些特征为我们理解湖泊辫状河三角洲的形成和演化提供了重要的线索。

The sequence characteristics of lake braided river delta are mainly manifested by its unique sedimentary sequence and sequence structure. Through a detailed investigation of the modern delta of Daidaihai Lake in Inner Mongolia, we can observe
a series of clear sequence characteristics, which provide important clues for us to understand the formation and evolution of lake braided river deltas.
湖泊辫状河三角洲的层序主要由三部分组成:底部沉积、三角洲平原沉积和三角洲前缘沉积。

底部沉积主要由河流携带的粗粒物质组成,如砂砾石等,这些物质在河流进入湖泊后迅速沉积,形成明显的底积层。

The sequence of lake braided river delta mainly consists of three parts: bottom sediment, delta plain sediment, and delta front sediment. The bottom sediment is mainly composed of coarse-grained materials carried by rivers, such as sand and gravel. These materials quickly deposit after the river enters the lake, forming obvious bottom sediment layers.
三角洲平原沉积则主要由河流带来的细粒物质组成,如粉砂和粘土。

这些物质在三角洲平原区域逐渐沉积,形成了平坦的沉积平原。

在这一阶段,由于河流的冲刷和搬运作用,平原上会形成一系列的河道和河漫滩,这些河道和河漫滩的沉积物构成了三角洲平原的主要沉积层序。

The sedimentation of delta plains is mainly composed of
fine-grained materials brought by rivers, such as silt and clay. These substances gradually deposited in the delta plain area, forming a flat sedimentary plain. At this stage, due to the erosion and transportation of rivers, a series of channels and floodplains will form on the plain, and the sediment of these channels and floodplains constitutes the main sedimentary sequence of the delta plain.
三角洲前缘沉积是湖泊辫状河三角洲层序的最上层,主要由湖泊中的细粒沉积物组成,如泥质沉积物。

这些沉积物在湖泊中逐渐沉积,形成了三角洲前缘的沉积层序。

在这一阶段,由于湖泊的波浪作用和湖水的流动,沉积物会在三角洲前缘区域形成一系列的沙坝和滩地,这些沙坝和滩地的沉积物构成了三角洲前缘的主要沉积层序。

The delta front sediment is the upper layer of the braided river delta sequence in lakes, mainly composed of fine-grained sediments in lakes, such as muddy sediments. These sediments gradually deposited in the lake, forming a sedimentary sequence of the delta front. At this stage, due to the wave action of the lake and the flow of lake water, sediment will form a series of sandbars and shoals in the delta front area. The sediment
of these sandbars and shoals constitutes the main sedimentary sequence of the delta front.
通过对内蒙古贷岱海湖现代三角洲的考察,我们可以发现,湖泊辫状河三角洲的层序特征具有明显的时空变化性。

在不同的时间和空间尺度上,湖泊辫状河三角洲的层序特征会有所不同,这主要取决于河流的流量、湖泊的水位、沉积物的类型和来源等因素。

Through the investigation of the modern delta of Daidaihai Lake in Inner Mongolia, we can find that the sequence characteristics of the lake braided river delta have obvious spatiotemporal variability. The sequence characteristics of lake braided river deltas vary at different time and spatial scales, mainly depending on factors such as river flow, lake water level, sediment type and source.
湖泊辫状河三角洲的层序特征是由其独特的沉积环境和沉积过
程所决定的。

通过对这些层序特征的研究和分析,我们可以更深入地理解湖泊辫状河三角洲的形成和演化过程,为后续的储层地质模型建立和油气勘探提供重要的科学依据。

The sequence characteristics of lake braided river deltas are determined by their unique sedimentary environment and
processes. By studying and analyzing these sequence characteristics, we can gain a deeper understanding of the formation and evolution process of lake braided river deltas, providing important scientific basis for the establishment of reservoir geological models and oil and gas exploration in the future.
五、储层地质模型建立

储层地质模型的建立是湖泊辫状河三角洲沉积体系研究的核心
内容之一。

通过对内蒙古贷岱海湖现代三角洲沉积的详细考察,我们可以根据湖泊辫状河三角洲的岩相、层序特征,结合区域地质背景,构建出储层地质模型。

The establishment of reservoir geological models is one of the core contents of the study on the sedimentary system of lake braided river delta. By conducting a detailed investigation of the modern delta sedimentation of Lake Daihai in Inner Mongolia, we can construct a reservoir geological model based on the lithofacies and sequence characteristics of the lake braided
river delta, combined with the regional geological background.
在建立储层地质模型时,我们采用了多种方法和手段,包括地质调查、钻探取样、地球物理勘探、测井分析等。

通过对贷岱海湖地区的详细地质调查,我们了解了该地区的构造背景、沉积环境、沉积序列等基本情况。

在此基础上,我们利用钻探取样获得的岩心资料,详细分析了湖泊辫状河三角洲的岩相、层序特征,确定了各沉积单元的类型、厚度、分布范围等。

When establishing a reservoir geological model, we adopted various methods and means, including geological surveys, drilling sampling, geophysical exploration, well logging analysis, etc. Through a detailed geological survey of the Daihai Lake area, we have gained an understanding of the basic information of the area, including its tectonic background, sedimentary environment, and sedimentary sequence. On this basis, we used core data obtained from drilling sampling to analyze in detail the lithofacies and sequence characteristics of lake braided river delta, and determined the types, thicknesses, and distribution ranges of each sedimentary unit.
同时,我们还结合地球物理勘探和测井分析,对储层的物性特征
进行了深入研究。

通过地震资料解释和测井曲线的综合分析,我们确定了储层的厚度、孔隙度、渗透率等关键参数,为储层评价和预测提供了重要依据。

At the same time, we also conducted in-depth research on the physical characteristics of the reservoir by combining geophysical exploration and well logging analysis. Through the comprehensive analysis of seismic data interpretation and logging curves, we have determined key parameters such as reservoir thickness, porosity, and permeability, providing important basis for reservoir evaluation and prediction.
在储层地质模型建立过程中,我们还注重模型的动态性和可预测性。

通过对现代三角洲沉积的考察,我们了解了湖泊辫状河三角洲沉积的动态变化过程,为模型的动态更新提供了基础数据。

我们利用先进的数值模拟技术和地质统计方法,对储层进行了精细刻画和预测,为后续的油气勘探和开发提供了有力支持。

In the process of establishing reservoir geological models, we also pay attention to the dynamics and predictability of the models. Through the investigation of modern delta sedimentation, we have gained an understanding of the dynamic
changes in lake braided river delta sedimentation, providing basic data for the dynamic updating of the model. We have utilized advanced numerical simulation techniques and geological statistical methods to finely characterize and predict reservoirs, providing strong support for subsequent oil and gas exploration and development.
通过对内蒙古贷岱海湖现代三角洲沉积的考察和研究,我们成功建立了湖泊辫状河三角洲储层地质模型。

该模型不仅揭示了储层的空间展布规律和物性特征,还为油气勘探和开发提供了重要的参考依据。

未来,我们将继续深化对该地区的研究,不断完善和优化储层地质模型,为油气资源的可持续利用做出更大的贡献。

We have successfully established a geological model of lake braided river delta reservoirs through the investigation and study of modern delta sedimentation in Daihai Lake, Inner Mongolia. This model not only reveals the spatial distribution pattern and physical characteristics of reservoirs, but also provides important reference basis for oil and gas exploration and development. In the future, we will continue to deepen our research on the region, continuously improve and optimize
reservoir geological models, and make greater contributions to the sustainable utilization of oil and gas resources.
六、内蒙古贷岱海湖现代三角洲沉积考察
A Study on the Modern Delta Sedimentation of Lake Daidaihai in Inner Mongolia
内蒙古贷岱海湖,作为华北地区重要的内陆湖泊,其现代三角洲沉积体系是研究湖泊辫状河三角洲岩相、层序特征及储层地质模型的理想场所。

本次考察旨在通过实地考察和综合分析,揭示贷岱海湖三角洲沉积的成因机制、发育过程及其对储层地质模型的影响。

Daidaihai Lake in Inner Mongolia, as an important inland lake in North China, is an ideal place for studying the lithology, sequence characteristics, and reservoir geological models of braided river delta in its modern delta sedimentary system. The purpose of this investigation is to reveal the genesis mechanism, development process, and impact on reservoir geological models of the delta sedimentation in the Dai Dai Lake through on-site investigation and comprehensive analysis.
在实地考察中,我们详细观察了贷岱海湖三角洲的地貌形态、沉积构造和沉积物特征。

通过高分辨率的地球物理勘探和钻探取样,我们发现三角洲沉积主要由砂质和泥质沉积物组成,沉积层序清晰,具有明显的层理构造和韵律性。

我们还观察到三角洲前缘地区的沉积物粒度较细,分布广泛,表明该区域经历了较强的水动力条件。

In the field investigation, we carefully observed the geomorphic morphology, sedimentary structures, and sediment characteristics of the Dai Dai Lake Delta. Through
high-resolution geophysical exploration and drilling sampling, we found that delta sediments are mainly composed of sandy and muddy sediments, with clear sedimentary sequences and obvious bedding structures and rhythmicity. We also observed that the sediment grain size in the delta front area is relatively fine and widely distributed, indicating that the region has experienced strong hydrodynamic conditions.
综合分析认为,贷岱海湖三角洲的沉积主要受到河流、湖泊和风的共同作用。

河流携带大量沉积物进入湖泊,形成辫状河三角洲的典型沉积特征。

湖泊的波动和风的作用则对三角洲的沉积过程产生了重要影响,导致沉积物在空间上的分布和层序上的变化。

Comprehensive analysis suggests that the sedimentation of the Dai Dai Lake Delta is mainly influenced by the combined effects of rivers, lakes, and winds. Rivers carry a large amount of sediment into lakes, forming a typical sedimentary feature of braided river deltas. The fluctuations of lakes and the influence of wind have a significant impact on the sedimentation process of deltas, leading to changes in the spatial distribution and sequence of sediments.
本次考察不仅为湖泊辫状河三角洲岩相、层序特征及储层地质模型的研究提供了丰富的基础资料,也为类似地区的沉积学研究提供了有益的借鉴。

未来,我们将继续深化对贷岱海湖三角洲沉积过程的认识,以期更好地预测和评价该地区的储层地质特征。

This investigation not only provides rich basic data for the study of lithology, sequence characteristics, and reservoir geological models of lake braided river delta, but also provides useful reference for sedimentological research in similar areas. In the future, we will continue to deepen our understanding of the sedimentary process of the Dai Dai Lake Delta, in order to better predict and evaluate the geological
characteristics of the reservoir in the region.
