摘　　要：对于超深油井而言,找漏堵漏施工难度比浅井更大。针对塔里木H油田油井高压、高温、高矿化度及井身结构复杂特点,通过优化工艺和施工步骤,总结出适用H油田的找堵漏技术。通过2015年8口找堵漏实践,堵漏成功率100%,累计增油3.16×104t,证明了该技术基本满足H油田超深井套管找堵漏需求。Casing leakage finding and plugging in utra-deep wells is more difficult than shallow wells. According to the characteristics of high pressure, high temperature and high salinity and complex wellbore structure of wells, casing leakage finding and plugging technique for H Oilfield was developed by optimizing technological process and construction procedure. Applications of casing leakage finding and plugging are made for 8 times in 8 wells with success rate of 100% , adding up oil by 3.16 × 104 t,which proved that this technique can basically meet the needs for casing finding and plugging in the ultra-deep well of H Oilfield.
