摘要
在页岩气水平井中,首段采用连续油管传输射孔进行不压井射孔作业,避免使用压井液,可以保护油气层,且起下速度快,时效性高;在井口带压条件下还能保证井控安全。酸化压裂作业后采用连续油管钻除桥塞,具有可控的操作优势,为后期投产提供了畅通通道。连续油管技术在焦石坝工区页岩气水平井中射孔与钻塞的成功应用,为页岩气水平井的开发提供了行之有效的解决手段。
The application of coiled tubing conveyed perforation in no-killing perforating operation in the first section of shale gas horizontal wells has the advantages of being free from kill fluid ,protecting oil-gas blanket ,fast round trip ,high timeliness and being safe in well control with the wellhead pressure condition .The application of coiled tubing in drilling plug following acid fracturing operation is controllable ,helping smooth later-period production . The successful application of coiled tubing technology in perforation and drilling plug of shale gas horizontal wells in Jiaoshiba Workzone has shed the light on the development of shale gas horizontal wells .
