【摘要】：川東南涪陵地區(qū)五峰組—龍馬溪組頁巖儲層地質(zhì)條件優(yōu),可壓性好。借鑒北美地區(qū)頁巖氣勘探開發(fā)成功經(jīng)驗,以實現(xiàn)網(wǎng)絡(luò)裂縫為目標(biāo),配套了滑溜水+線性膠壓裂液、低密度覆膜砂支撐劑、網(wǎng)絡(luò)壓裂參數(shù)優(yōu)化以及電纜泵送橋塞/射孔聯(lián)作等分段壓裂關(guān)鍵工藝技術(shù),現(xiàn)場應(yīng)用增產(chǎn)效果顯著,探索形成了適合于涪陵地區(qū)海相頁巖儲層特點的水平井網(wǎng)絡(luò)裂縫壓裂技術(shù)體系。
[Abstract]:The shale reservoir of Wufeng-Longmaxi formation in Fuling area of southeast Sichuan has excellent geological conditions and good compressibility. Drawing lessons from the successful experience of shale gas exploration and development in North America, in order to realize the network crack, the sliding water linear glue fracturing fluid and low density coated sand propensant are matched. The key technology of segmented fracturing, such as the optimization of network fracturing parameters and cable pumping bridge plug / perforation, has a remarkable effect on increasing production in the field. A horizontal well network fracture fracturing technology system suitable for marine shale reservoir in Fuling area has been developed.
