摘　　要：电位场在地表的变化反映了地下不同介质层的电阻率变化特性,因此本文采用基于电位法下的监测技术对地表电位进行测量,采用基于有限差分方法和光滑约束最小构造方法对地表的电位值进行数据的反演处理,得到注水驱油层的电阻率分布变化,从而对注水油田进行直观可视的监测,较为准确地推断出含油区域.为了验证反演数据的准确度,通过实际工程应用将数据处理的电位等值线示意图、储层电阻率等值线示意图以及储层饱和度等值线示意图做了对应比较,得到理想的结果,具备实际利用及参考价值.The changes of potential on the surface reflect the underground resistivity variations of different layers,therefore,based on the monitoring technology of potential method,the measurement of potential can be applied.Especially,the inversion processing of surface potential relies on the finite difference method and the smooth constraint minimum structure method to achieve the variety of property of resistivity underground,finally,inferring the oil area.In order to verify the accuracy of the data inversion,through the practical engineering applications,the data processing of potential contour sketch map,reservoir resistivity contour sketch map and reservoir saturation contour sketch map made corresponding comparison,getting ideal corresponding results with actual use and reference value.
