摘　　要：为了进一步提高小井眼井的开发效果,对于钻遇在低渗透储层和产量未达到经济开采指标的小井眼油井,需要进行压裂改造。吐哈油田公司开展了89 mm套管小井眼压裂工艺技术研究,完成了Y341-70型封隔器的研制和改进,配套了井下工艺管柱,优化了压裂施工工艺,并完成了6井次现场试验,均顺利完成施工,增液、增油效果良好。With its steady strengthening oil exploration, the slim hole was increased. For the effective exploration of slim hole, the fracturing of slim hole, such as low-permeability reservoir and low-yield, need to be improved. The research of Tuha＇s Ф89mm casing slim hole fracturing was successfully carried out on 6 wells and Y341-70 packer was developed, equipped with down2 hole technique string, fracturing operation was optimized, and a good result was achieved.
