摘　　要：垂直线源电成像技术依托于套管井供电,不仅野外作业简便,而且可大幅度增加探测深度和成像精度,并能在不影响油井正常生产条件下实施作业。此法特别适用于油田开发中后期生产中油层注水推进前沿监测和剩余油分布状况研究。文中从井—地方式的电场特征出发,介绍了该技术的成像理论,并在S油田选取15口套管井作为供电电极,在每口套管井周围布设18条放射状、6~8周同心圆状的测量电极,分别进行测量,再将每次测量结果综合在一起,获得该区油层的含水饱和度分布。与该区实际含水饱和度分布相比较,表明电成像技术在油田开发中有广阔的应用前景。The electric imaging technique of vertical line power depends on supplying power by cased well, which not only is feasible for field operation, but also can greatly increase the surveying depth and imaging precision and implement operation without affecting normal production of oil well. The method is especially suitable for monitoring the water-injection front advance in oil-producing and studying the distribution of the remaining oil in the late stage of oil-fields development. Starting from the feature o...
