山东省地热资源开发利用现状调查与问题分析

山东省地热资源类型多且分布广，资源储量丰富，开采条件好，是名副其实的地热资源大省。本文采用逐井调查方法，对山东省范围内地热井数量、开发利用方式、地热流体开采量、地热井与油气资源矿业权重叠等进行了调查，对开发利用过程中存在问题进行研究分析。截至2020年底，全省共有地热井1862眼，主要包括洗浴与疗养模式、洗浴与疗养兼养殖与种植模式、养殖与种植模式、供暖兼洗浴模式四种模式；全省地热流体开采总量约1.405×108m3/a，其中供暖开采量约1.216×108m3/a，供暖面积约4060×104m2；康乐用开采量约0.166×108m3/a，养殖及其他用开采量约0.068×108m3/a。对油气资源矿业权（采矿权、探矿权）与地热井重叠进行论述，分析了地热开发利用过程中存在的问题，为今后全省地热资源的开发利用提供了依据。

Investigation and Problem Analysis on Development and Utilization of Geothermal Resources in Shandong Province

Geothermal resources in Shandong province has many types, wide distribution and good mining conditions. It is a real province of geothermal resources. By using well by well investigation method, the number of geothermal wells, development and utilization mode, exploitation of geothermal fluid, overlap of geothermal wells and mining rights of oil and gas resources in Shandong province have been investigated, and the problems existing in the process of development and utilization have been studied and analyzed. By the end of 2020, there are 186 geothermal wells in Shandong province, mainly including bathing and recuperation mode, bathing and recuperation and breeding and planting mode, breeding and planting mode, heating and bathing mode. The total amount of geothermal fluid exploitation is about 1.405×108m3/A, of which the heating production is about 1.216×108m3/A, heating area about 4060×104m2. The exploitation amount for recreation is about 0.166×108m3/A, and the exploitation amount for aquaculture and other purposes is about 0.06799×108m3/a. The overlap of oil and gas resources mining rights (mining rights and exploration rights) and geothermal wells has been discussed, and the problems existing in the process of geothermal development and utilization have been analyzed. It will provide a basis for the development and utilization of geothermal resources in the whole province in the future.
