摘　　要：吐哈油田原始储隔层应力差小,尤其是水平井压裂裂缝垂向延伸较大,给压裂增产带来了一定的难度.本文通过对吐哈地应力分析,提出了水力喷射分段、水平井机械隔离分段和水平井限流段等压裂技术,应用效果良好,对压裂增产的下一步研究也具有重要意义.Little differential stress of Tuha Oilfield＇s original storage compartment, especially the large fracture cracks of horizontal well on vertical extension, makes it difficult to increase production by fracturing. Through the stress analysis of the Turpan-Hami in this thesis,sub-fracturing technologies, as Subsection Hydraulic jet, Sub-horizontal wells mechanical isolation, Horizontal well Limiting paragraph and etc are put forword. These technologies have effective application and have important meaning for further study on increasing fracturing production.
