使用线电极供电的直流电阻率法预测砂岩构造型油气藏的实验与研究

实验结果表明，无论井中是否下有套管，采用本提出的（深井中线电极供电的）井中－地面工作方式的直流电阻率法梯度装置测量，砂岩构造型油气藏埋藏不太深、围岩电阻率变化不大、地表平坦的条件下，均可较好地对油气藏进行重向及横向预测、确定油气藏边界位置、确定油气藏高点位置、对油气藏进行开发监测等。

Experimental research on sand structural hydrocarbon trap prediction using linear-electrode direct current resistivity method

It has been experimentally shown that hydrocarbon trap prediction(includingthe lateral and vertical properties, boundary, high position, development monitorand so on)can be desirably achieved by using the borehole-ground direct current re sistivity method with linear-electrode configuration located in a cased or uncaseddeep hole when there are favourable conditions:the proper depth of sand structuralhydrocarbon trap,the gentle variation of surrounding rock resistance , and smoothlandform.
