Abstract：The corrections of static effect in MT method is always the issue that widely following with interest by the people engaged in electric exploration at home and abroad,who presented a variety of solution methods,among which the parallel curve shift correction method is currently mainly-used method.The apparent resistivity between sections may produce systematic errors after correction and unequal apparent resistivity values may be produced at intersect of two lines when using the parallel curve shift correction method for areal exploration;on the other hand,the sudden variations in curve values resulted from real geologic structural changes may be viewed as static shift and removed by using the method,which resulted in loss of useful information.For this reason,the paper presented static correction method of planer cluster that implements Hanning filtering first on plane,then the cluster analysis is implemented for apparent resistivity curves at each surveying point in exploration area,that can automatically reach the goal of the corrections in separate zones of structural units.The comparison of the applied cases by using the method with seismic sections in same segments showed that both of them are comparable and that means the method is effectiveness.
