摘要 在通许凸起西段尉氏北部,通过MT和二维地震的物探方法组合,基本查明了工作区地层分布和构造特征,依据3个低阻异常圈定了3个远景区;结合区域资料、地热地质调查和综合分析,布置了探采结合井,预测了探采结合井钻遇地层。经钻孔验证,在新近系馆陶组热储层最大涌水量100.39 m^3·h^-1,最大降深64.54 m,井口温度53℃,取得了初步成果。该套组合勘查技术对地质构造复杂、热储埋藏较深地区地热勘查行之有效,对河南省中深层地热勘查有一定的示范作用。 Three remote areas were identified according to three low resistance anomalies in the northern part of yuushi area, which were studied by the combination of MT and 2D seismic Geophysical methods. Combined with regional data, geothermal Geological Survey and comprehensive analysis, the exploration and mining combined well was arranged, and the exploration and mining combined well drilling strata were predicted. After drilling, it was verified that the maximum inflow of water in the hot reservoir of the Nei Tuantao Formation was 100.39 m^3/h, the maximum depth of depth was 64.54 M, and the wellhead temperature was 53℃, and preliminary results were obtained. The combined survey technique is effective for geothermal exploration in areas with complex Geological structure and deep hot storage, and has a certain demonstration effect on mid-deep geothermal exploration in Henan Province.
