山东省水热型地热资源及其开发利用前景

山东省地热资源分布广泛,资源储量丰富。从山东省大地构造特征和大地热流值分布规律入手,根据地热传导理论,对山东省水热型地热资源的分布规律和资源量进行了研究。研究表明,山东省地热资源的分布受区域地质构造严格控制,根据地热成因可分为隆起山地板内深循环对流型和沉积断陷盆地传导型。结合地热成因和热储类型,进一步将全省分为4个地热资源区: I—鲁东地热区; II—沂沭断裂带地热区; III—鲁西隆起地热区; IV—鲁西北地热区。山东省地热资源量折合标准煤为143.73´10⁹ t,不考虑回灌条件,现状地热开发利用量不足已查明可采量的3%,具有较大开采潜力。根据地热资源分布特征合理有效地开发利用地热资源,是山东省压减化石能源消费、推动能源结构优化、改善大气环境质量的有效途径。

Analysis of hydrothermal geothermal resources and its prospect of development and utilization in Shandong

Shandong Province has a wide range of geothermal resources and abundant resource reserves. According to the theory of geothermal conduction as well as the geological structure and the earth heat flow in Shandong Province, the geothermal distribution and resource quantitise were discussed in this paper. The results show that the distribution of geothermal resources in Shandong Province is strictly controlled by regional geological structure. According to geothermal genesis, they can be divided into uplift mountain deep circulation type and sedimentary fault basin conduction type. Based on geothermal genesis and thermal storage types, the province is divided into four geothermal resource areas: Ⅰ- East Shandong geothermal area; Ⅱ- Yishu fault zone geothermal area; Ⅲ-West Shandong uplift geothermal area; Ⅳ-Northwest Shandong geothermal area. The amount of geothermal resources is equivalent to 14.373 billion tons of standard coal. The current geothermal exploitation amount is less than 3% of the recoverable reserves without regard to artificial recharge, so the potential is still great. Reasonably developing and utilizing geothermal resourcs in accordance with the geothermal resources distribution characteristics, is an effective way to reduce fossil energy consumption, optimize energy structure, and improve the quality of atmospheric environment.
