摘要
安徽省禾泉农庄位于蚌埠市禹会区,为满足农庄后续发展需要,在农庄周边开展了以综合物探为主的地热资源调查工作。综合物探方法包括地面高精度磁法、音频大地电磁测深(AMT)及可控源音频大地电磁测深(CSAMT),综合区内地质条件和本次综合物探成果,取得主要成果与结论:(1)明确区内地热勘查的主要方向为含水断裂构造;(2)推测区内存在北东向F1、近南北向F2、近南北向F3、北北东向F4共4条断裂构造,其中F4深大断裂构造有利于地热形成和导水,为优选可能含水断裂构造;(3)圈定V1线2000点附近为地热宜井井位,建议钻深1 400 m。本次成果一方面验证了综合物探方法在隐伏断裂构造探测的有效性,为后续进一步的地热勘查提供方向;另一方面作为系统的地热调查方法,对相近地区开展相似工作具有重要参考意义。
Hequan Farm in Anhui Province is located in Yuhui District,Bengbu City,and in order to meet the subsequent development needs of the farm,geothermal resource investigation work mainly based on comprehensive physical exploration was carried out in the vicinity of the farm.Comprehensive physical exploration methods include ground high-precision magnetic method,audio geomagnetic bathymetry(AMT) and controlled-source audio geomagnetic bathymetry(CSAMT),and the geological conditions in the area and the results of this comprehensive physical exploration have achieved the following main results and conclusions:(1)it is clear that the main direction of geothermal exploration in the area is water-bearing fracture structure;(2)it is assumed that there are four fracture structures in the area,namely NE F1,near-south-north F2,near-south-north F3,north-northeast F4.Among which F4 deep and large fracture structure is conducive to geothermal formation and water conduction,and is the preferred possible water-bearing fracture structure;(3)It is circled that near 2000 points of V1 line is a suitable well location for geothermal wells,and it is recommended to drill to a depth of 1400 m.On the one hand,the results of this project have proved the validity of the comprehensive physical exploration method in the detection of hidden fracture structures,and provided the direction of the subsequent geothermal exploration;on the other hand,as a systematic geothermal investigation method,it can be used for the geothermal investigation in the similar area.On the other hand,as a systematic geothermal investigation method,it has important reference significance for similar work in similar areas.
