摘要
通过对渭河盆地热背景、资源量、热储层、开发利用现状及开采技术的发展等方面对开发利用现状进行了阐述。渭河盆地莫霍面上隆,岩石圈厚度薄,沉积层生热与深部热流传导的热量导致渭河盆地地热资源异常丰富,主要分布在西安、渭南、咸阳等地。盆地地热资源储量高、用途广,但中深层地热资源开发利用需要研究机构、政府和产业部门等联合出台相应的规范和标准,以规范市场、确保安全绿色高效生产。当前和未来渭河盆地中深层地热资源开发主要是采灌结合与深井地埋管相结合的方式,深井地埋管开发是地热开采的新思路,也是今后技术攻关的主要方向。
The development and utilization status of the Weihe Basin is described by the background of thermal background, resources, thermal reservoirs, development and utilization status and development of mining technology. The Moho surface in the Weihe Basin, the thickness of the lithosphere is thin, and the heat generated by the sedimentary layer and the heat transfer from the deep heat flow are extremely rich in geothermal resources in the Weihe Basin, mainly distributed in Xi'an, Weinan and Xianyang. The geothermal resources in the basin are high in reserves and widely used. However, the development and utilization of geothermal resources in the middle and deep layers require joint research institutes, governments, and industrial departments to issue corresponding regulations and standards to regulate the market and ensure safe, green and efficient production. The current and future development of geothermal resources in the middle and deep layers of the Weihe Basin is mainly a combination of mining and irrigation combined with deep wells. The development of deep wells is a new way of geothermal exploration and the main direction of future technological breakthroughs.
