摘　　要：在总结以往射孔、压裂、测试井施工经验的基础上,开发了适用于海上平台射孔、压裂、测试与水力泵快速返排的联作工艺,研制了与该工艺管柱配套的海上专用压裂水力射流泵,7″大套管用防砂卡器,大通径可锁定开关井全通径压控选择测试阀(LPR-N测试阀)。并在中海油某海域探井A井进行现场试验,结果表明,该工艺技术能够满足海上平台不动管柱一次完成射孔、压裂、测试与水力泵快速返排求产的施工要求,安全、可靠,具有试油周期短,作业费用低,快速、及时返排压裂残液,有效地防止压裂残液对油层造成二次污染的特点。该工艺技术的成功实施,为以后海上油田快速评价储层提供了新的技术手段。Based on summarization of former operation experiences of perforation,fracturing and well test,a combination technology of perforation,fracturing and well test and quick unflow with hydraulic pump on offshore platform has been developed,and a dedicated fracturing hydraulic jet pump,sand control card for 7 inches wide casing,full bore pressure-controlled choice test valve with big full size locked switch( LPR- N test valve) to match this process have been studied and field test is completed at A well in a certain sea area of CNOOC. the results show that the technology can satisfy the offshore fixed string to conduct operation requirements of perforating,fracturing,production test and hydraulic pump quick flowback,having characteristics of being safe,reliable,short test period,low operation cost,rapid and timely unflow of fracturing fluid residue,effectively preventing fracturing fluid residue to cause secondary pollution to reservoir. the successful implementation of the technology provides a new technical means for rapid evaluation of the reservoir in offshore oilfield.
