| 济新断裂位于华北地台区黄淮中断坳与山西中台隆交接部位，为修武断陷和武陟凸起的分界线，零星的民用地热井显示断裂周缘有较好热异常，该区覆盖层厚度大，中深部地热资源评价难度高。本文利用重力、可控源音频大地电磁测深、测氡等综合物探方法进行了探测，结合以往磁测、二维地震、测温等资料对导热、控热断裂及热储有利区进行了解译，物探成果修正了基底武陟凸起太古宇与下古生界的不整合边界，提出了太古宇裂隙发育区，为发现该区太古宇带状裂隙热储提供了重要依据。后续地热钻井证实了这一结果，在太古宇与新近系不整合界面发现热流体，千米埋深水温 65 ℃左右。并通过收集周边地热井资料，在武陟凸起轴部太山镇—徐营镇一带太古宇变质岩区发现了大面积的地热资源。 |
| 英文摘要: |
| The Jixin Fault is located at the junction of the Huanghuai Fault Depression and the Zhongtai Longin Shanxi Province in the North China Platform area. It serves as the boundary between the Xiuzhi Depression andthe Wuzhi Uplift. Scattered civilian geothermal Wells indicate good thermal anomalies around the fault. The overbur-den thickness in this area is large, making the evaluation of middle and deep geothermal resources difficult. This pa-per conducts detection by using comprehensive geophysical exploration methods such as gravity, controllable sourceaudio electromagnetic sounding, and radon measurement. Combined with previous magnetic measurement, two-dimensional seismic, and temperature measurement data, it interprets the favorable areas of heat conduction, thermalcontrol fractures, and thermal storage. The geophysical exploration results correct the unintegrated boundary betweenthe Archean and Lower Paleozoic in the Wuzhi Uplift of the basement, and propose the fissure development area ofthe Archean. It provides an important basis for the discovery of the Archean banded fissure thermal reservoir in thisarea. Subsequent geothermal drilling confirmed this result. Hot fluid was discovered at the unconformity interface be-tween the Archean Universe and the Neogene, with a water temperature of about 65 ℃ at a burial depth of one kilo-meter. By collecting data from surrounding geothermal Wells, a large area of geothermal resources was discovered inthe Archean metamorphic rock area between Taishan Town and Xuying Town on the axis of the Wuzhi Uplift. |
