物探技术在地热井勘探中的实践探析

Practical Analysis of Geophysical Prospecting Technology in Geothermal Well Exploration

为探明区域赋水情况,确定地热井的位置,本文以吉林省白山市抚松县松江河镇西北方位的勘探区为工程背景,通过音频大地电磁法结合直流电测深法对该区域进行探测,根据岩性确定出凿井深度,并推测了的地热井的出水温度,结合区域布置测线的视电阻率情况,最终确定出了该区域地热井的位置与相关参数。

In order to determine the location of geothermal wells,this paper takes the northwest of Songjiang River Town,Fusong County,Baishan City,Jilin Province as the engineering background,through the audio magnetotelluric method combined with direct current bathymetric method to detect the area,according to the lithology to determine the drilling depth,and speculated the geothermal wells water temperature and water,combined with the regional layout of the survey line of apparent resistivity,finally determined the location of geothermal wells and related parameters.
