摘　　要：普光气田的H2S平均含量达到15%,在投产初期就出现井筒堵塞情况,严重影响天然气产量。分析原因是硫沉积、水合物、暂堵剂等附着在井壁,导致节流或堵塞。热水吞吐解堵工艺和连续油管冲洗解堵工艺都存在不足。采用无固相压井液压井、连续油管热水冲洗工艺,解决了普光气田井筒堵塞问题,并优化了放喷流程。为高酸气田的开发提供技术支持。The gas field of Puguang average hydrogen sulfide content is up to 15%,in the initial production wellbore blockage,which seriously affected the production of natural gas.After analysis,the main cause is sulfur deposition,hydrate,and temporary blocking agent attached to the borehole wall,causing the throttle or blockage.Deficiencies exist in hot water throughput plugging process and continuous tubing flush deplugging process.Solid phase killing hydraulic wells,coiled tubing hot water process,comprehensive measures to solve the Puguang gas field wellbore plugging problems,and optimize the venting process.Provide technical support to the high acid gas field development.
