摘要: 冀中坳陷地热能资源十分丰富,大量石油井钻达地热田热储层,地热田主要受坳陷内凹凸相间的地质结构控制。地层岩性、盖层厚度、水流交替、断裂传导、热储层埋深等影响地温场变化。区内赋存着元古宇—下古生界弱交替带、上古生界—古近系交替阻滞带、新近系强交替带三大地热含水系统,热储层分为孔隙型、裂缝型和裂缝—溶洞型3类,其中基岩裂缝型热储层温度高,热能量大,优选留北地热田利用废弃油井进行地热能利用实验。

Abstract: Jizhong Depression is very rich in geothermal resources, and a large number of wells have been drilled in geothermal reservoir. Geothermal fields are mainly controlled by geologic structures in the Depression. The geothermal field is affected by formation lithology, cover thickness, water exchange, fracture conductivity, and depth of geothermal reservoir, etc. Three big geothermal aquifer systems developed in the Depress, i.e. the weak alternation zone between Proterozoic and Lower Paleozoic, the Upper Paleozoic-Paleogene alternation blocking zone, and the strong alternation zone of Neogene. There are three types of geothermal reservoir, i.e. porous-type geothermal reservoir, fracture-type geothermal reservoir, and fracture-cave-type geothermal reservoir, among which the base rock fractured reservoir has high temperature and high geothermal energy. Experiment on the utilization of geothermal energy is conducted by use of abandoned wells in Liubei geothermal field.

Key words: geothermal resource, geothermal field, geothermal reservoir, resources, Jizhong Depression
