川东南涪陵地区五峰组—龙马溪组页岩储层地质条件优,可压性好。借鉴北美地区页岩气勘探开发成功经验,以实现网络裂缝为目标,配套了滑溜水+线性胶压裂液、低密度覆膜砂支撑剂、网络压裂参数优化以及电缆泵送桥塞/射孔联作等分段压裂关键工艺技术,现场应用增产效果显著,探索形成了适合于涪陵地区海相页岩储层特点的水平井网络裂缝压裂技术体系。
The Wuping Formation-Longmaxi Formation shale reservoirs in the Fuling area of southeast Sichuan have good geological conditions and good compressibility. Draw lessons from the successful experience of shale gas exploration and development in North America, to achieve the goal of network cracks, supporting slippery water + linear gel fracturing fluid, low density coated sand proppants, network fracturing parameters optimization and cable pumping bridge plug / shot Hole linkage and other sub-stage fracturing key technologies, field application of significant stimulation effect, explore the formation of the Fuling area of marine shale reservoir characteristics of horizontal well network fracturing technology system.
