The high resistivity layer shall not be infinitely great or close to surface, otherwise the layer will prevent the current entering the anomaly body and no anomaly will be produced.
而当高阻屏蔽层在平面上趋于无限大而且埋深较大时，这时因进入异常体的电流很小，甚至趋于零，所以地面上观测不到异常体产生的磁异常。
High formation water salinity reduces resistivity contrast between oil layer and water layer.
高矿化度的地层水，降低了油层与水层的电阻率对比度。
