摘要: 为了在一些老油区寻找深部剩余油的存在,在大量水槽模拟实验的基础上,提出了一种新型的直流电阻率勘探方法-以钻井套管作电极的非无穷远三极剖面法,通过测量电极的视电阻率,然后经去干扰处理后得到梯度异常曲线,从而寻找油气。理论分析和实验结果表明:采用该法,在按规则网格布钻的油区,非无穷远三极剖面法有可能成为寻找剩余油的一种廉价而高效的勘探方法。

Abstract: On the basis of a great number of aquarium analogue experiments, a novel D. C. electric resistance expecting method?the non-boundless trielectrode section method, which uses casing tubes in the wells as electrodes, has been developed by the authors. This paper reports and discusses the experimental results. It is indicated that for oilfields with regular well patterns this method may provide a cheap and efficient tool for thesearching of residual oils.

Key words: residual oil, aquarium experiment, electric resistivity, casing tube, trielectrode
