摘要
牛驼镇地热田位于京津冀腹地,呈北东向展布。本文通过地热田区域的地层岩性、地温场特征等方面对牛驼镇地热田热储与盖层的性能进行评价,阐述了牛驼镇地热田具有地热储量丰富、断裂构造发育、温度较高、埋藏深度较浅和地下水质优良等特点,从而具有极大的开发利用价值。通过对地热田区域的断裂构造及华北地幔亚热柱与地热热源之间的联系对地热田成因模式进行分析研究,最终论证得出华北地幔亚热柱通过牛东断裂等一系列深大断裂带为牛驼镇地热田提供源源不断的热量,同时断裂带对地热田的热量提供了封闭作用,并为地热田提供了充足的地下水。
Niutuozhen geothermal field is located in the hinterland of Beijing, Tianjin and Hebei, NE trending.This paper through the aspects of lithology, regional characteristics of geothermal field on the Niutuozhen of geothermal reservoir and caprock performance evaluation, expounds the Niutuozhen geothermal field has rich reserves, the development of fracture structure, high temperature, shallow burial depth and groundwater quality excellent characteristics, which has great development the value of. Based on the genetic model of geothermal field between fault structures of the region and the North China sub mantle plume and the geothermal source contact analysis, finally comes to the conclusion that the North China sub mantle plume through a series of Niudong fault deep fault belt is Niutuozhen geothermal field provide continuous heat of geothermal heat the sealing effect and fracture, and provides abundant groundwater for geothermal field.
