摘要: 水平井裸眼分段压裂技术是开发非常规油气藏的有效手段。对裸眼分段压裂关键工具进行了改进。膨胀式专用悬挂器采用金属颗粒辅助橡胶悬挂方式，室内试验结果表明， ?114.3 mm型悬挂器悬挂载荷增加100 kN，设计采用液压机械双重丢手，增加了施工安全性；?114.3 mm型裸眼封隔器采用可膨胀金属环结构后环空承压能力增加30 MPa，采用2段胶筒的裸眼封隔器承压能力达到60 MPa，但再增加段数承压能力增加不明显；激光表面处理后的滑套球座表面硬度达到HRC55。压裂管柱室内试验验证了其满足现场施工要求，在低渗透区块2口井中成功应用，分别顺利完成10段、11段裸眼分段压裂施工。现场应用效果表明新式裸眼分段压裂完井工具性能优越、安全稳定。

Abstract: Openhole staged fracturing technology of horizontal well is an effective mean for unconventional oil gas reservoir development. Besides, openhole multistage fracturing tools need design improvement, parameter enhancement and reliability intensification. Expandable liner hanger deploys mental particles auxiliary rubber suspension. Laboratory test results reveal that the holding weight of 114.3 mm hanger could increases 10 t, and hydraulic mechanical dual release plan improves the safety of fracturing process. The annulus pressure of openhole packer in size 114.3 mm with expandable metal ring is 30 MPa higher than packer without ring. Openhole packers with 2 rubber tube could hold annulus pressure up to 60 MPa while more elements packers increase annulus sealing ability slightly. Inner cone hardness of sliding sleeve after laser surface processing arises to HRC55. Indoor test data of fracturing string qualifies its capability of meeting the requirements of construction site. Fracturing tools get success in two wells of low-permeability district with 10 stages, 11 stages fracturing job separately. 5260 tons oil collects from the two wells in total after production. Field application represents that new openhole multistage fracturing tools have excellent properties and security and stability in actual usage.
