摘　　要：原井油管内壁锈蚀,将会严重影响下入的油管堵塞阀的工作,使其无法正常在油管内长时间锚定坐封,给拆装防喷器或拆装采油(气)树作业带来井控风险。通过现场施工案例分析和分享,浅谈油管内壁腐蚀对油管堵塞阀作业的影响,为后期类似施工井提供参考。Inner wall corrosion of original well tubing can severely affect the operation of a tubing plug valve,preventing them from properly anchoring and sealing within the tubing over extended periods.This poses well control risk during the installation or removal of blowout preventers or oil(gas)trees.Through the analysis and sharing of job cases,the impact of tubing inner wall corrosion on tubing plug valve operation is discussed,providing reference for similar future operations.
