山东省郓城县城区地热地质条件分析

Geological Condition Analysis of Geotherm in Yuncheng County, Shandong Province

摘要:

通过地温调查及物化遥感勘探资料的分析,推断郓城县城区存在一SW—NE向的地热异常带。热储层主要为奥陶纪马家沟组,盖层为厚达千米的石炭系—第四系,导水控热构造是以SN向为主的断裂。如按预选的3个地热孔位施工,推测井底水温可大于50℃。

Abstract:

Through temperature survey and geophysical and geochemical remote sense information analysis, it is regarded that there is a SN-NE geothermal abnormal belt in Yuncheng county. Ordovician Majiagou formation is major reservoir stratum, and Carboniferous-Quaternary are its covering with the depth of 1000m. Transmission and heat-controlling structure is a fault with SN trend. According to pre-collect three geothermal poles, water temperature in the well is more than 50℃.
