油藏工程方案英文1. IntroductionThe development of an oil field is a complex and challenging task that requires careful planning and execution. Reservoir engineering plays a crucial role in the development of an oil field as it involves the optimization of production rates, recovery factors, and overall field management. In this report, we will outline a reservoir engineering plan for the development of an oil field, taking into consideration the geological, geophysical, and engineering aspects of the field.2. Reservoir characterizationThe first step in the development of an oil field is to characterize the reservoir in terms of its geological and petrophysical properties. This involves the analysis of core samples, well logs, and seismic data to determine the reservoir's porosity, permeability, fluid properties, and potential hydrocarbon reserves. This information is crucial for the design of the production and reservoir management strategies.3. Well placement and drillingThe next step in the reservoir engineering plan is to determine the optimal well placement and drilling strategy. This involves the identification of potential drilling locations based on the reservoir characteristics and the subsurface geology. The well design and drilling plan should take into consideration the reservoir's heterogeneity, fluid viscosity, and pressure regime to maximize production rates and recovery factors.4. Reservoir simulationOnce the well placement and drilling strategy are determined, a reservoir simulation study is conducted to predict the reservoir's behavior under different production scenarios. This involves the construction of a reservoir model based on the geological and engineering data, and the simulation of fluid flow, pressure distribution, and production rates. The reservoir simulation study is essential for optimizing the field development plan, and for forecasting the field's production and recovery over time.5. Enhanced oil recovery (EOR)In many mature oil fields, enhanced oil recovery (EOR) techniques are employed to improve the recovery factor and increase the overall production rates. EOR techniques such as water flooding, gas injection, and chemical flooding are designed and implemented based on the reservoir's characteristics and the production challenges. The selection of the EOR method is often based on reservoir simulation and field tests to determine the most effective technique for the field.6. Field development and infrastructureThe final step in the reservoir engineering plan is the design and implementation of the field development and infrastructure. This involves the construction of production facilities, well pads, gathering systems, and transportation pipelines to bring the produced oil to market. The field development plan should be designed to optimize production, minimize operational costs, and adhere to environmental regulations and safety standards.ConclusionsIn conclusion, the development of an oil field requires a comprehensive reservoir engineering plan that takes into consideration the geological, geophysical, and engineering aspects of the field. The reservoir engineering plan outlined in this report involves reservoir characterization, well placement and drilling, reservoir simulation, enhanced oil recovery, and field development. By carefully planning and executing the reservoir engineering plan, an oil field can be developed to optimize production and recovery, and to maximize the field's economic value.。

油气工程英语(English)

油气工程英语(English)

油气工程英语UNIT 1Origin of Oil and Gas 石油和天然气的成因Oil and gas result mostly from dead microorganisms buried quickly in anoxic environments , where oxygen is so scarce that they do not decompose. This lack of oxygen enables them to maintain their hydrogen-carbon bonds , a necessary ingredient for the production of fossil fuels. Newly developing ocean basins ,formed by plate tectonics and continental rifting (deforrnation) , provide just the right conditions for rapid burial in anoxic waters. Rivers fill these basins with sediments carrying abundant organic remains. Because the basins have constricted water circulation ,they also have lower oxygen levels than the open ocean.石油和天然气大多是由缺氧环境下迅速被掩埋的死亡微生物生成的。

这种环境氧气奇缺致使这些微生物无法分解。

氧气的缺乏能够使那些死去的微生物保持他们的碳氢键——这是产生化石燃料的一种必要组分。

由板块构造运动和大陆裂谷作用(变形)而新近演化形成的大洋盆地,正好为在缺氧水域的快速埋藏提供了合适环境。

三、划分开发层系的意义
合理划分
1.有利于充分发挥各类油层的作用
高、低渗透率层合采,高渗层含水上升快,形成水窜,
而低渗层生产能量难以发挥;
高、低压层合采,低压层往往出油少,甚至形成层间
倒灌。
K1,h1 K2,h2
11
2.有利于发挥采油工艺的作用 目前分层注水、分层采油和分层控制技术还未达到很细的
高产率层作为单独一套层系开发的单位原油储量,可以比 低产率油层小一些。但是,必须保证获得的产油量有利可图。
19
4)不应把几个可采储量较大的油层合并为一套层系 应以产率和最终技术经济指标作为划分开发层系的厚度标
13
四、划分开发层系的原则
(1)特性相近的原则 沉积条件相近、渗透率相近、非均质程度相近、油层分布面 积相近、油砂体几何形态及分布状态相近; 同一开发层系内,油层的构造形态、油水边界、压力系统和 原油物性应比较接近。 以保证各油层对注水方式和井网具有共同的适应性,减少开 采过程中的层间矛盾。 (2)具有一定的储量 以保证油田满足一定的采油速度,并具有较长的稳产时间和 达到较好的经济指标。
第三节 开发层系划分与组合
内容提要
一、多油层非均质性特点 二、划分开发层系所需要考虑的因素 三、划分开发层系的意义 四、划分开发层系的原则 五.划分开发层系的一般方法

• 油层的非均质性是影响多油层开发部署和开发效果的最 重要的因素。
• 合理地划分与组合开发层系是从开发部署上解决多油层 油田垂向层间非均质性的基本措施。

(2)生产动态因素 每一油层的年采油量,每一油层的采油动态,组合成开发层
系后几个生产层的产能和开采动态,组合后开发层系的含水变 化,开发各阶段持续的时间,每一油层或组合为层系的合理采 油量等指标。 (3)技术工艺因素

Chapter Six Petroleum Production
Production may be considered as that section of the oil industry concerned with conveying(传送) hydrocarbons(烃) from the reservoir(油藏) to surface, and the separation(分离) of oil, gas, water, and solids to the extent necessary to provide a saleable primary product(初级产品) such as crude oil, NGL(natural gas liquids), and gas.

Reservoir Production Mechanisms(机理)
The production mechanisms which owe their existence to these sources of energy are referred to as “water drive” (水驱), “solution gas drive” (or “depletion drive”) (溶解气驱), and “gas cap drive”(气顶驱) respectively. The natural drainage of the oil through the reservoir rock under its own gravity(重力) provides a further production mechanism. A combination of drive mechanisms may operate in the same reservoir. Generally, however, one system will dominate(占支配地位) the others and the relative importance of these will change with time during the production of oil and for this reason it is convenient to consider each type of drive mechanism separately and care must be taken during the development of an oil field to use the reservoir drive pressures to their maximum extent(最大程度).
