摘要
Abstract
As a kind of clean and renewable energy with large reserves and wide distribution,geothermal energy needs to be recharged in the same layer in the process of development and utilization.At present,the completion technology of sandstone recharge well construction is mainly water filter pipe completion and hierarchical cementing filter pipe completion,but they all have some disadvantages,such as rapid attenuation of recharge capacity,long-term recharge prone to blockage and so on.However,perforation completion is widely used in oil wells,which is an important measure to improve oil well productivity,but there is little research on the application of this technology in geothermal wells.This paper analyzes the influence factors of perforation completion productivity and the advantages and disadvantages of filter pipe completion,and analyzes the examples of perforation completion and filter pipe completion,and compares the two kinds of completion productivity test in sandstone area,so as to provide reference for geothermal well construction in sandstone area.关键词
