在黑龙江省某工区进行可控源音频大地电磁测深勘查工作中,利用实测剖面内电性分布,推测测线通过地段的地质构造和岩性分布情况,控制深度3 000 m。通过CSAMT勘测并结合拟二维反演程序,对于探测深部地质构造取得了一些成果,证明了可控源音频大地电磁法在地热资源勘查工作中的有效性。
In the controllable source audiometry survey of a certain area in Heilongjiang Province, using the electrical distribution in the measured section, it is presumed that the survey line passes the geological structure and lithology distribution of the section and the depth is controlled to 3 000 m. Through the CSAMT survey combined with the quasi two-dimensional inversion program, some results have been obtained for the exploration of deep geological formations, and the effectiveness of the controllable source audio-frequency geomagnetic magnetotellurism in geothermal resource exploration has been proved.
