摘要:

山东省热储类型多、分布广,资源储量丰富,但地热资源赋存规律及其富集机制尚需系统研究。本文基于地热井测温、大地热流测量、地热资源勘查、钻获地热井及抽水试验和长期动态监测资料,圈定了控热、导水地质构造和地热异常分布区,将山东省地热资源划分为鲁东隆起、沂沭断裂带、鲁西隆起和鲁西北坳陷4个地热区,分别论述了各地热区地热系统的热储类型、开放程度、热源水源及其运移和可更新能力,以及水流热流富集构造赋存位置。集成水源开放状态、热源机制和水热富集热储赋存特征等主要地热能控制要素,将地热系统划分为3种聚热富水模式:(1)开放—对流—腔管状型地热系统聚热富水模式;(2)弱开放—对流传导—带状层状型地热系统聚热富水模式;(3)封闭—对流传导—带状层状型地热系统聚热富水模式。揭示了各聚热富水模式的热源及其聚集机制、水源及其富集机理、水热可更新能力和富集热储赋存规律,为找热定井提供了靶区定位依据。

Abstract:

Shandong Province possesses abundant geothermal resources with widespread distribution of geothermal reserviors of different types. However, the occurrence rules and accumulation mechanism of geothermal resources are not well understood. In this paper, based on previous geothermal well temperature logging, geothermal exploration, well drilling, pumping test and long-term dynamic monitoring data, we explain the distribution characteristics of geothermal resources in Shandong, and delineate the geological structure that controls the geothermal flow and water conduction. The heat and water sources and accumulation mechanisms and the occurrence of thermal reservoirs were explored. Four geothermal resource areas were delineated: eastern Shandong, Yishu fault zone, western Shandong uplift and northwestern Shandong depression. Combining the characteristics of major ore-controlling factors such as geothermal water source, heat source and occurrence of thermal reservoir, the geothermal systems were divided into three models: open-convection-cavity tubular; weakly open-convection/conduction-banded stratified; and closed-convection/conduction-banded stratified. Insights on the heat/water sources and accumulation mechanisms under different types of geothermal systems and the occurrence law of hydrothermal accumulated reservoirs provide a basis for targeted geothermal exploration and well drilling.
