摘　　要：塔里木英买力油田缝洞型碳酸盐岩深井裸眼段挤水泥是技术难题。井径不规则,大裂缝、大溶洞发育,漏失严重,高温、超深等均给挤水泥带来困难。为提高挤水泥成功率及降低成本,技术人员根据油田特有的地质特点和生产实践,总结出平推注水泥浆、桥塞暂堵打塞等工艺,取得了很好的堵水效果,进一步挖掘了油气井潜力。The fractured-vuggy carbonate reservoir in Tarim Yingmaili oilfield is characterized by irregular hole diameter,large cracks,developed cave,severe leakage,high temperature and ultra-depth,the squeeze cementing was difficult in deep openhole section.Based on the oilfield geologic characteristics and production practice,the horizontal cement injection and bridge plug temporary plugging technology were researched and applied,and good water plugging effect was obtained.Combining with the actual situation,some squeeze cementing methods suited for Tarim fractured-vuggy carbonate reservoir were discussed and analyzed.
