The Surface Electromagnetic Prospecting(SEP)System developed by ourselves have already been tested in China and abroad.The test comparison with other similar field instruments was carried out.Test results show that the SEP System has similar specifications with the other instruments,and some performances are even better.In order to test the consistency,stability and reliability of the SEP System(including electric receiver stations and magnetic sensors),well-designed batch comparison tests have been conducted in Zhangbei,Hebei.In the tests the SEP System received natural source electromagnetic data and controlled source electromagnetic data.The apparent resistivity of the natural source field and the controlled source field are consistent,and the errors are within a reasonable tolerance.The comparison of a large amount of data proves both the receiver stations and the magnetic sensors have reliable and stable performances.Our practice proves the effectiveness of our comparison test approach,and the test resultsshow that the SEP System can acquire high-quality electromagnetic data for the deep hydrocarbon and other mineral resource exploration.
