摘　　要：针对大庆外围低渗透油田储层物性差,常规压裂效益低,缝网压裂施工费用高、施工周期长的问题,通过借鉴缝网压裂原理以及常规压裂优势,在常规压裂方案基础上,优选易造复杂裂缝的滑溜水作前置液,优化施工排量等工艺参数,形成直井滑溜水压裂方案并进行试验。滑溜水压裂与常规压裂相比,不但成本增加较少,而且由于规模小降低了缝网压裂的施工费用和施工周期。从目前效果和效益看,滑溜水压裂形成了一定规模的裂缝网络,提高了常规压裂井的效益产量,为大庆外围低渗透油田提高措施效果提供技术支持。In view of the problems of poor reservoir physical properties,low efficiency of conventional fracturing,high cost and long construction period of fracture network fracturing in the peripheral Low-permeability Oilfields of Daqing,based on the principle of fracture network fracturing and the advantages of conventional fracturing,on the basis of conventional fracturing scheme,the slip water which is easy to create complex fractures is selected as the prepositional fluid,and the construction displacement is optimized to form a straight well slip hydraulic fracturing formula Case and test.Compared with conventional fracturing,slip water fracturing not only has less cost increase,but also reduces the construction cost and construction period due to its small scale.In terms of current effect and benefit,slick water fracturing has formed a certain scale of fracture network,improved the benefit production of conventional fracturing wells,and provided technical support for improving the effect of measures in Low-permeability Oilfields around Daqing.
