引言 VSP是井傍区域地震测量的极有效的方法之一。常规测量方法需使钻井中断,将检波器置入井中,其结果是成本很高,且操作风险加大。为解决这些难题,一种可行的方法是以随钻噪声作为震源,在地面接收逆VSP信号。 试验系统称之为SEISBIT。该系统由AGIP和OGS公司联合设计和研制。直接在野外完成数据采集和预处理后,可用标准的VSP软件包对数据集进行处理。 在放置一条或多条检波点测线后,可用半自动的方式采集数据。设计了几个导频监测器用
Introduction VSP is one of the most effective methods for seismic survey in the wellbore area. Conventional measurement methods need to be interrupted drilling, the geophone into the well, the result is a high cost, and increased operational risk. To solve these problems, one feasible approach is to use the noise of the drilled-in noise as the source of the sound and receive the inverse VSP signal at the surface. The test system is called SEISBIT. The system was jointly designed and developed by AGIP and OGS. After data acquisition and preprocessing are done directly in the field, the dataset can be processed using the standard VSP software package. After placing one or more detector points, the data can be collected in a semi-automatic manner. Several pilot monitors are designed
