PPV测试在可控震源施工中的应用
|
摘要
在国外可控震源地震勘探中,若工区内有建筑物或其它设施,石油公司经常会要求地震队在施工前或施工中做PPV地震监视测试。该测试主要是在可控震源扫描时,测量离激发点不同距离的地面振动能量,从而判断地震勘探激发源在不同激发距离对周围建筑物的影响程度,以制定合理的可控震源偏点距离。文中详细地介绍了用于进行PPV测试的设备———Mini SuperGraph的硬件、软件和操作方法,以及使用该设备获得的测试结果进行分析后,正确地确定安全、合理的可控震源偏移距的方法。
In international seismic exploration with vibrator,PPV test is usually required to done by oil company before the start-up or during seismic project if there is buildings or other facilities in exploration area.The aim of PPV test is to confirm the safety distance between the seismic source and surrounding buildings.This paper focuses on the test part of PPV,the hardware and software of MINI SuperGraph and operation method.In addition,this paper introduces how to correctly determine the safety,reasonable controllable seismic source offset after upon the test results.
