四川盆地深层页岩气钻井关键技术新进展及发展展望OA北大核心CSTPCDEI
New progress and development prospect of key technologies for drilling of deep shale gas wells in the Sichuan Basin
四川盆地页岩气资源丰富,目前深层页岩气已成为该盆地天然气增储上产的重点领域,但随着埋深增加和构造背景变化,地质工程条件将更加复杂,钻井过程中将面临井漏风险高、井下工具高温易失效、水平井轨迹控制难度大等技术难题.为此,在系统分析已完钻井实钻数据的基础上,依据深层页岩气区块地质工程特征,系统梳理了影响安全优快钻井的关键技术难点,形成了以地质工程一体化导向技术、钻井提速技术、防漏治漏与复杂防治技术为主体的深层页岩气安全优快钻井关键技术系列.研究结果表明…查看全部>>
The Sichuan Basin is rich in shale gas resources,and at present,deep shale gas has become an important field for the increase of natural gas reserves and production in this basin.With the increasing of burial depth and the changing of structural setting,however,the geological and engineering conditions will get more complicated to bring several technical difficulties in the drilling process,such as high risk of lost circulation,failure of downhole tools at h…查看全部>>
