摘要

湖南省热水圩地热田是东南沿海地区温度最高、储量最大的地热田之一,热储形态为带状。为分析该热田的资源分布规律,指导类似地区的勘探,在区内布置了高精度重磁测量及可控源音频大地电磁测量(CSAMT)工作,构建了区内断裂系统,分析了优良热储位置的地球物理场特征,取得以下认识:① 区内发育两组4个方向断裂,第一组为早期形成相互垂直的NNE和NWW向断裂,第二组为晚期形成夹角约75°近NS和NEE向断裂;② 优良热储位于NWW向断裂F₄和近NS向断裂F₇交汇带附近,地球物理场显示为剩余重力场低值区与高值区的边界,磁性低异常与高异常的边界,电法剖面上的垂向电性低阻带。

Abstract：

The Reshui-Town geothermal field in Hunan Province is one of the highest temperature and largest reserves geothermal field in the southeastern coastal area, and the reservoir form is banded. In order to analyze the distribution law of the reservoir and guide the exploration in similar areas, high-precision gravity and magnetic measurement and controlled source audio magnetotelluric measurement (CSAMT) were arranged in the area to construct the fault system and analyze the geophysical field characteristics of an excellent thermal reservoir zone. The results as following: 1. Two groups of four-direction faults were developed in the area. The first group was the early vertical NNE and NWW faults, and the second group was the late formation angle of about 75° near NS and NEE. 2. The excellent thermal reservoir is located near the intersection of NWW fault F₄ and near NS fault F₇. It shows the boundary of gravity between the low value area and the high value area, the boundary of low magnetic anomaly and high anomaly, electricity Vertical electrical low resistance zone on the cross section of the method.

Key words： Reshui-Town geothermal field banded geothermal reservoir fault system geophysical field geothermal exploration
