一个隐蔽油气圈闭的查找

THE SEARCH FOR A BURIED RESERVOIR TRAP

大港油田地调指挥部

本文叙述在一个油气资源丰富,构造简单的斜坡地带,运用地震波瞬时参量、频谱等信息的变化,查明了一个单井出油,而出油原因长期搞不清的地层岩性圈闭。通过钻探又获新的工业油流。

In this paper, the author described how a buried reservoir trap was found out in a declivous region where the stratum were abundant in oil and gas and the structures were rather simple. There was a producing well in this region but ever since the beginning the whys and wherefores of the oil producing were not made clear. The discovery of this trap was a good explanation for the producing of the oil because this is in essence a stratigraphic lithologic trap. The trap-determination was by virtue of the simultaneous parameters and the frequency spectrum of the simultaneous parameters and theffrequency spectrum of the seismic waves. Some oil wells were drilled in line with the new information and commerical oil were obtained.
