咸阳地热WH1井砂岩地层回灌试验研究与应用

Experimental Study on Geothermal Well Recharge Test in Sandstone Formation

摘要:

地热是一种新型绿色能源，我国地热资源丰富，部分区域地热开发已经形成一定规模，具有一定的研究基础，地热尾水回灌形成可持续循环利用技术是目前遇到的突出难题，在砂岩地层回灌尤为困难。汾渭盆地的地热能源较为丰富，已经形成了规模开发，咸阳地热WH1井首次进行了砂岩回灌尝试，获得了施工及回灌等相关数据。对砂岩地层尾水回灌进行了试验，积累了施工经验，为后继施工打下了基础。

Abstract:

Geothermal energy is a new kind of green energy and its development has formed a certain scale in some regions in China. The geothermal tail water recharge as a sustainable recycling technology currently becomes a prominent problem; especially when it is applied in sandstone layer. There is abundant geothermal energy in Fen-Wei basin where the scale development has formed. The sandstone recharge was tried in WH1 geothermal well in Xianyang for the first time with the related data of construction and recharge. Tail water recharge test was made to accumulate the construction experience, which lays the foundation for subsequent construction.
