| 摘 要： | 从天津大地构造特征和地层分布入手，综合分析了岩溶热储特征.认为天津地区主要大地构造格局从西北向东南依次为冀中拗陷、沧县隆起和黄骅拗陷，主要断裂有北东向的沧东断裂、天津断裂以及北西向的宁河-宝坻断裂.岩溶地热田主要分布在沧县隆起上，发育了王草庄、大城、潘庄、双窑和小韩庄凸起等地热田.研究认为蓟县系雾迷山组在天津全境普遍分布，岩性为深灰色粗晶白云岩、隧石条带状白云岩，裂缝岩溶发育，孔渗性较好，是主要热储层.寒武系、奥陶系热储在沧县隆起核部大面积缺失，在其他地区广泛分布，是主要热储层之一.沧县隆起的热流值较周围地区高，地热水的来源主要为北部蓟县山区，热水运移的最重要通道是大断裂以及不整合面.

| Abstract: | The characteristics of karst thermal reservoir are analyzed comprehensively based on the geotectonic characteristics and stratigraphic distribution of Tianjin City. It is believed that the main tectonic framework are Central Hebei depression, Cangxian uplift and Huanghua depression from northwest to southeast, with the major faults of NE-trending Cangdong fault, Tianjin fault and NW Ninghe-Baodi fault. The karst geothermal fields are mainly distributed on the Cangxian uplift where geothermal fields are developed in Wangcaozhuang, Dacheng, Panzhuang, Shuangyao and Xiaohanzhuang salients. The research suggests that the Jixianian Wumishan Formation, composed of dark gray coarse-grained dolomite and chert banded dolomite, is widely distributed throughout Tianjin with developed crevice karst and good porosity-permeability, which serves as the main thermal reservoir. The thermal current value of Cangxian uplift is higher than that of the surrounding areas. The main source of geothermal water is the mountainous area of Jixian county in the north with the major fault and unconformity as the most important migration channel. |
