多种物化探方法在贺州某地热温泉勘查中的综合应用
|
摘要
勘查工作区紧邻贺州温泉,地理条件优越,具有较大的地热开发潜力。通过多种物化探方法组合探测应用来查找主要的导水储水断裂,确定了构造破碎带的主体位置,圈定了有利的储热区域,并布置了验证钻孔,工程验证结果与探测结论吻合。该多种物化探方法在地热温泉勘查中的综合应用成效突出,可以引荐于类似地热勘查项目。
The exploration work area is adjacent to Hezhou Hot Spring which has favorable geographic conditions and great potential for geothermal development.Through the combined application of various geophysical and geochemical exploration methods to verify the main water-conducting and water-storing faults,this paper determined the main location of the structural fracture zone and blocked out the favorable heat-storing areas,while the conclusions were in consistent with the results of the verification boreholes.This combined application of various geophysical and geochemical exploration methods in geothermal hot spring exploration proved itself an effective and efficient method which can be introduced in other similar geothermal exploration projects.
