摘要:
塔河油田套损井呈逐年增多趋势，且部分井出现重复套漏。采用以挤水泥为主的套损井治理工艺，同时配套封隔器卡封、套管短回接等技术进行套损井治理，存在一定局限性。高强度膨胀堵剂由高强度膨胀堵剂灰及其他物质按照一定比例调配而成，通过其特有的成分快速形成互穿网络结构，膨胀率达6%，封堵强度由常规水泥的7～8 MPa提高至24 MPa，具备良好的抗温性能和可泵注性，保证了施工安全。现场试验6井次，最大封堵井深
60440 m，最高施工压力30 MPa，封堵成功率100%。高强度膨胀堵剂对后期塔河油田超深井套损治理具有一定指导意义。
Abstract:
Casing damage wells are increasing year by year, and some wells have repeated casing leakage in Tahe Oilfield. There are some limitations in the treatment of casing damage wells using cement squeeze technology with packer blocking, casing short return and other techniques. The highstrength expansion plugging agent is made up of highstrength expansion plugging agent ash and other substances in a certain proportion. Through its unique components, it quickly forms an interpenetrating network structure, with an expansion rate of 6%. The plugging strength is increased from 7-8 MPa of conventional cement to 24 MPa, with good temperature resistance and pumpability, which can ensure construction safety. It has been used in 6 wells for field test, the maximum plugging depth is 60440 m, the maximum construction pressure is 30 MPa, and the plugging success rate is 100%. The highstrength expansion plugging agent has certain guiding significance for casingdamage treatment of ultradeep wells in Tahe Oilfield.
