摘　　要：井—地电位测量是在地表向注水井中套管施加一个大电流 ,通过测量地表加注高矿化度的导电流体前后的电位分布 ,经数据处理及反演计算 ,求出注水各小层的电阻率分布 ,进而计算出各小层的剩余油饱和度分布状况 ,指出油藏的挖潜方向。从临 1 7- 2 2井区应用情况来看 。The well earth electric potential image is the technic that a big electric current is applied on the casing of the waterflood input well on the surface of the earth,the distribution of the electric potential is measured before and after the injection of the high mineral conduct electricity liquid,the distribution of specific resistance in the injective layers is calculated after the dealing with the data and inversion calculation,thus the potentiality of the reservoir is pointed out.The application in the pattern of Lin 17 22 conforms with the production status.
