引言 本文讨论了近年来井下固定检波器及其在被动和主动地下储气藏监测方面的进展。这是CGG、ELF、GDF、IFP和TOTAL等公司联合研究顶目的部分结果。这一项目的目标之一是研制和测试三分量固定检波器。 固定检波器是为时间推移地震应用而推出的,它也可用于声波监测。我们完成的试验与这两类应用相对应,它是把一组三个固定检波器置于同一口井中,井在位于GDF的储气区中,地点位于Germigny—Sous—Coulombs(巴黎,法国)。
Introduction This paper discusses the downhole fixed geophones and their advances in passive and active subterranean reservoir monitoring in recent years. This is the result of a joint study of CGG, ELF, GDF, IFP and TOTAL. One of the goals of this project is to develop and test a three-component fixed detector. Fixed geophones are introduced for time-lapse seismic applications and can also be used for acoustic monitoring. The tests we completed correspond to these two types of applications by placing a set of three stationary geophones in the same well and in a gas field located in the GDF at Germigny-Sous-Coulombs (Paris, France) .
