气顶逆驱型低阻油层成因机理及实例分析

here is not any notice about the problems in low resistivity oil reservoir in present research, which forms from the exploitation changing of hydrocarbon pools that lead oil water contact moves. Based on research of muti-wells with routine logging data, this paper interpret the influence in wells at different tectonics position cause by a high energy gas cap in the reservoir reasonably, propose a kind of possibility that low resistivity reservoir will outputs oil because of the moving of oil water contact caused by high energy gas cap, with mass works in Comprehensive comparison of new and old well, and analysis of old well exploitation history and fluid property. It summarized the genetic mechanism, feature and key of interpretation and evaluation.
