下辽河盆地干热岩资源勘探靶区研究

EXPLORATION TARGET AREA OF HOT DRY ROCK RESOURCES IN LOWER LIAOHE BASIN

摘要: 下辽河盆地特殊的构造位置使区内拥有高的大地热流值和较大的地温梯度，具有巨大的地热资源潜力. 通过对下辽河盆地地温场、热流密度及潜山分布的研究，认为位于下辽河盆地西部凹陷斜坡带的高升-曙光-欢喜岭潜山带是寻找干热岩的有利靶区，并分析了下辽河盆地干热岩资源成因模式.

Abstract: There is high terrestrial heat flow value and large geothermal gradient in Lower Liaohe Basin due to its unique tectonic location, with huge geothermal resources potential. Based on the study of geothermal field, heat flux and buried hill distribution in Lower Liaohe Basin, it is considered that the Gaosheng-Shuguang-Huanxiling buried hill belt located in the slope zone of western sag of Lower Liaohe Basin is a favorable target for hot dry rocks prospecting, and the genetic model of hot dry rock resources in the area is analyzed.
