鲁北深部砂岩热储开发地质环境变形效应研究

山东省深部砂岩热储资源丰富，热储开发利用对区域经济社会发展具有重要促进作用。但如果不注重深部热储的适度、有序开发，超出其临界量后可能会引发区域地面沉降等不良地质环境问题，因而，研究深部砂岩热储开发引发的地质环境变形问题意义重大。本文针对山东省鲁北典型深部砂岩热储区热储开采的地质环境影响问题进行深入研究，确定了开采量、开采层位等因素导致的热储层沉降量，分析了热储层沉降对该区地面总沉降的贡献。对深入认识鲁北地区深部砂岩热储的地质环境效应，合理开发深部热储资源提供借鉴与依据。

Study on Geological Environment Influence Caused by Deep Thermal Reservoir Exploration in Sandstone in Shandong Province

Shandong Province is rich in deep sandstone thermal reservoir resources, and the development and utilization of thermal reservoir play an important role in promoting regional economic and social development. If deep thermal reservoir can not be paid attention to moderate and orderly development, geological environment problems can be caused, such as regional land subsidence after exceeding its critical amount. Therefore, it is of great significance to study geological environment deformation problem caused by the development of deep sandstone thermal reservoir. In this paper, geological environment impact of thermal reservoir exploitation in typical deep sandstone thermal reservoir area in northern Shandong province has been studied furthurly. The settlement of thermal reservoir caused by factors, such as mining output and production horizon has been determined, and the contribution of thermal reservoir subsidence to total land subsidence in this area has been analyzed. It will provide some references and basis for further understanding geological environment effect of deep sandstone thermal reservoir in northern Shandong province and for rational development of deep thermal reservoir resources.
