孔隙型地热井回灌作为一个世界性的课题，已有很多专家学者进行过不同程度的研究，但均未能有较大的突破。探讨不同成井工艺对孔隙型地热井回灌的效果，选取天津滨海新区的两眼不同成井工艺的新近系馆陶组地热井为例。。采用自然回灌的模式，分析两井的回灌能力、可持续时间及累计回灌动水位，并分别计算了回灌水文地质参数。试验结果表明：射孔成井的地热井回灌效果要明显优于滤水管成井的。

As a global issue,the porous geothermal well reinjection have been researching for many experts and scholars in different degree,but failed to have a larger breakthrough. Taking two geothermal wells of different completion technology of the Guantao formation of Neogene in Binhai New Area of Tianjin as an example,In order to explore the reinjection effect of different completion technology on porous geothermal wells. In the paper,we used the natural reinjection mode to analyzes the reinjec-tion ability,sustainable time and cumulative reinjection dynamic water level of two well,and to calculate the recharge hydrogeo-logical parameters. The test results show that:the perforation wells geothermal well reinjection effect is much better than the fil-ter pipe wells.
