JY1HF井是涪陵地区第一口海相页岩气水平井，为了获得商业性页岩气产量，对JY1HF水平井进行了分段压裂设计和工艺优化。在借鉴北美海相页岩气压裂经验的基础上，通过该井岩心资料、测井、岩石力学等数据，对龙马溪组页岩储层进行了压前评价。采用岩石力学试验、X衍射试验、诱导应力场计算和体积压裂动态模拟等方法，开展了压裂段数、压裂液、支撑剂、射孔方案和压裂工艺优化等综合研究，提出采用组合加砂、混合压裂工艺，泵送易钻桥塞射孔联作工艺进行大型水力压裂改造的方案。JY1HF井共压裂15段，累计注入液量19972.3m3，支撑剂968.82m3，放喷测试获得无阻流量16.7×104m3/d的高产页岩气流。结果表明，龙马溪组海相页岩采用水平井大型分段压裂技术，可获得较大的有效改造体积。JY1HF井的成功压裂为中国海相页岩气压裂改造积累了经验。

In order to obtain commercial shale gas from Well JY 1HF ,the first marine shale gas hori-zontal well in Fuling Area ,multi-stage fracturing design and process optimization for this well were carried out .By learning from successful stimulation experience in North American marine shale gas play ,pre-frac evaluation of this well was performed using core data ,log data and rock mechanics data .Through rock me-chanics test ,X ray diffraction test ,induced stress field calculation and volume fracturing dynamic simula-tion ,research on fracturing stages ,fracturing fluid ,proppant ,perforating and fracturing technology optimi-zation had been developed .A set of large hydraulic fracturing scheme of combination of proppant ,hybrid fracturing ,integrated pumping easy-drillable bridge plug and perforating was proposed .15 stages were frac-tured in Well JY1HF ,the cumulative injection fluid volume was 19 972.3 m3 ,the cumulative injection prop-pant volume was 968.82 m3 and absolute open flow was 16.7 × 104 m3/d .The results showed that the multi-stage hybrid fracturing could reach large effective stimulated reservoir volume in Longmaxi marine shale horizontal wells .Successful fracturing of Well JY1HF will provide valuable experience for China ma-rine shale gas fracturing .
