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。
