东营市基岩地质背景与地热资源分布

Geological Background and Geothermal Resource Distribution of Basic Rocks in Dongying City

摘要:

东营市地热资源丰富,地热分布受储盖条件及基岩构造背景等因素制约,热水储层为多层结构系统。在一定深度范围内,地温总体呈高、低相间的带状展布。其平面展布,相对高温区与基岩潜凸区一致,相对低温区与基岩潜凹区一致。地热主要为正常增温传导型,在潜凸与潜凹结合部位,可能存在水热对流型。

Abstract:

Geothermal resource is very rich in Dongying city. I ts distribution is controlled by reserve covering condition and tectonic backgroun d of basic rocks, and hot water reservoir is multi-strata system. In a certain d epth scope, temperature distributes in stripe while high and low temperature are contacted with each other. Compared with high temperature area, its plane distr ibution is conformity with buried lifting area of basic rocks; while compared wi th low temperature area, its plane distribution is conformity with buried depres sion area of basic rocks. Geotherm in this area majorly belongs to normal temper ature increasing conduction type. In combining section of buried lifting and dep ression areas, water and therm convective type geotherm maybe occurred.
