济宁市南部地热资源分析

Preliminary Exploration of Geothermal Resources in South of Jining City

摘要:

济宁市南部地处鲁西南潜隆之济宁凹陷，经地质调查、物探、钻孔验证等分析表明，济宁城区南部地热属层控岩溶裂隙型层状热储中低温地热田，经初步概算，区内奥陶系灰岩热储地热资源总量为3.424×1017J，折合标准煤1.17×107t，开发利用前景十分可观。

Abstract:

Southern Jining city is located in Jining depression of Luxinan hidden uplift in Shandong province. Through analysis of geological investigation, geophysical prospecting and drilling verification, it is showed that geothermal resource in southern Jining city belongs to low temperature strata bound fissure type geothermal field. Through preliminary estimation, total amount of thermal storage of geothermal resources of Ordovician limestone in this region is 3.424 x 1017J, which is equivalent to standard coal of 1.17 x 107 t. It has a quite considerable prospect for development and utilization.
