【摘要】 鲁西碳酸盐岩岩溶热储分布面积广,热水储量大,是山东省地热资源开发的重要目标。笔者等利用残余厚度厚法或“印模”法恢复了鲁西地区怀远期、加里东晚期、印支期、燕山期、喜马拉雅期等五期古地貌,各期岩溶高地、岩溶缓坡、岩溶洼地分布特征具有一定继承性及差异性。现今热储经历了6个时期同生岩溶、表生岩溶及埋藏岩溶综合影响而成,印支—燕山期构造格局决定了区内南、中、北段的岩溶热储发育演化差异性。结合各期古地貌及断裂分布特征,圈定了菏泽凸起、单县凸起、阳谷凸起等热储勘探有利区,以期为未来地热资源勘探提供指导。更多还原

【Abstract】 Objectives: The carbonate karst geothermal reservoir in western Shandong( Luxi) area exhibits a wide distribution area and substantial hot water reserves, making it a crucial target for geothermal resource development in Shandong Province. Methods: We utilized the residual thickness method and " impression " method to reconstruct five paleogeomorphologies during the Huaiyuan, Caledonian, Indosinian, Yanshanian, and Himalayan periods. Results: The distribution characteristics of karst highlands, karst gentle slopes and karst depressions in each period have certain inheritance and difference. The present geothermal reservoirs have experienced six periods of syngenetic, supergene and buried karst. The Indosinian—Yanshanian tectonic styles determine the difference in the development and evolution of karst geothermal reservoirs in the south, middle and north sections of the area. Conclusions: Combined with the characteristics of paleogeomorphology and faults distribution, the favorable areas for geothermal reservoir exploration such as Heze uplift, Shanxian uplift and Yanggu uplift are delineated, in order to provide theoretical guidance for future geothermal exploration.更多还原
