从 Petrel 2007 开始 Synthetics 模块有了很大改进。最重要的变化是其结果可在 Global well logs 下有相应的 synthetic 目录，其相应时深关系可在数据表中显示。对同一口井可产 生多个合成记录，如图 1-1，1-2 所示。

Petrel地震地质解释和建模使用技巧
Petrel地震地质解释和建模使用技巧Petrel 合成记录工作流制作合成地震记录，进行层位标定和确定时深关系是地震解释工作中非常重要的环节。
从Petel2009.1.1，开始Petrel里有两个制作合成记录的模块，一个叫Synthetics，一个叫Seismic-Well tie。
这里介绍如何使用Synthetics模块制作合成地震记录。
从Petrel 2007开始Synthetics模块有了很大改进。
最重要的变化是其结果可在Global well logs下有相应的synthetic目录，其相应时深关系可在数据表中显示。
对同一口井可产生多个合成记录，如图1-1，1-2所示。
Synthetics模块制作合成记录工作流主要分为两大步骤：按照已有数据产生合成记录通过welltop 进行时深关系调整（bulkshift或sqeeze/stretch）一、 生成合成记录1. 双击synthetic模块，打开合成记录主界面（如下图），选择create new folder，从界面中well 到well seismic 四个界面对合成记录中所需数据进行选择或创建，如图2所示。
Well：选择要做合成记录的井，可多选，但每口井必须有相应的数据（DT和子波）。
Sonic and time：确定原始输入数据及时深关系。
根据实际数据品质，如果有checkshot，可用来做DT曲线校正；所有井上时深关系以工区井目录，以及每口井的Settings界面里Time界面下设置为准，Synthetics界面里的Overwrite global time log项不启用。
Create synthetic seismogram：创建合成记录选择创建合成记录所需数据：Density、Acoustic Impedence、Reflectiotion coefficients和Wavelet。
如果这些数据都不存在，或者希望修改参数重新创建，则点击黄色星状按钮创建新数据。

然后按下面的顺序打开软件。
1. 双击桌面上的Petrel图标启动Petrel。
2. 如果是第一次运行Petrel，在执行Petrel运行前会出现一个Petrel的介绍窗口。
3. 打开Gullfaks_Demo项目。
点击文件>打开项目，从项目目录中选择Gullfaks_2002SE.pet。
二、界面介绍（一）、菜单条/ 工具条与大多数PC软件一样，Petrel软件菜单条有标准的“文件”、“编辑”、“视图”、View等下拉菜单，以及一些用于打开、保存project的标准工具，在菜单条下面的工具条里还有更多工具。
在Petrel里，工具条还包含显示工具。
此外在第二个工具条里还有位于Petrel 项目窗口的右端的按钮，它具有附加的Petrel相关的功能。
后面的工具条称为功能条，这些工具是否有效取决于选择进程表中的哪个进程。
操作步骤1.点击上面工具条中的每一项看会出现什么。
你可以实践一些更感兴趣的选项。

地球上板块与板块之间相互挤压碰撞

地震就是人们平时所说的地动，人们感觉不到它的存在，而只能靠仪器观测到，其实它和刮风、下雨一样，只是一种灾害性自然现象。
在公共场合听从现场工作人员的指挥，不要慌乱，不要拥向出口，要避免拥挤，要避开人流，避免被挤到墙壁或栅栏处。

Overview
• Converting pre-Petrel2007.1 seismic projects • Merge navigation and SEG-Y data • Seismic server • Use faults as constraint when autotracking • Modify autotrack parameters • Edit fault segments • Horizon operation example • Surface operation example • Artificial light • Generate surface from attribute maps • Generate variograms from attribute maps • Complete structural model • Create velocity model using a seismic velocity cube • Create velocity model using stacking velocities
Where events are dipping, interpretation may leak over the top or under the base of faults.
Modify autotrack parameters
1. The ”best practice” is to use a polygon to limit the autotracking to an area of interest.Open a 2D Window and display seismic and interpretation data in that window
