山东温石塘地热田回灌补源压裂增注试验

地热田回灌补源是实现地热能资源可持续开发的新技术，用于解决地热能补给，提高地热能利用率。其方法是在距开采井一定距离，施工一眼注水井，通过注水井向地下注入一定比例的水量与热源再交换，提高热能资源量。介绍了对注水井实施压裂、增加对地热井注水量的新工艺。经水力压裂和抽水试验，增注水效果明显，为我国合理开采利用和保护地热能资源提供了一种新的技术方法。

Fracturing Test of Groundwater Recharge in Wenshitang Geothermal Field of Shandong

The groundwater recharge for geothermal field is a new technology to realize the geothermal energy resources sus-tainable development, solve the geothermal energy supply and improve the utilization efficiency of geothermal energy.The technical method is implemented by a water injection well constructed at a certain distance from the exploiting well, by ex-change of certain proportion water injected to underground through injection well and the heat source to improve the heat re-source.This paper introduces a new technology to increase the geothermal well injection by fracturing the water into injec-tion well.By hydraulic fracturing and pumping tests, obvious effect of water injection increase is obtained, which provides a new technical method for reasonable exploitation and protection of geothermal energy resources for China.
