摘要
涪陵页岩气田是我国首个实现商业化开发的大型页岩气田,其钻井工程技术体系对其他页岩气田钻井具有示范作用。将涪陵页岩气田钻井工程技术发展分为勘探发现、开发试验、一期产能建设和二期产能建设4个阶段,并从地表地质特征、井壁稳定、井眼轨迹控制以及固井质量等方面论述了该气田发展历程中遇到的钻井技术难点。针对上述技术难点,从平台地面布局、布井方案、低成本优快钻井、井眼轨迹控制、井筒完整性评价等方面总结了9项钻井关键技术,以期为其他页岩气田的钻井提供借鉴。同时,在此基础上围绕"稳产增效、提速降本",指出了涪陵页岩气田下一步的钻井技术需求,提出了针对性的钻井技术发展建议,以持续提高涪陵页岩气田的钻井技术水平。
The Fuling Shale Gas Field is the first large-scale commercially developed shale gas field in China,and its drilling technical systems can be used as a model for the drilling of other shale gas fields.The development of drilling technologies in Fuling Shale Gas Field was divided into four stages,including exploration and discovery,development test,the first-stage production construction,and the second-stage production construction.The drilling challenges were discussed in aspects of surface geological characteristics,wellbore stability,hole trajectory control and cementing quality.Aiming at the above challenges,nine key drilling technologies were summarized covering platform surface layout,well deployment plan,low cost and rapid drilling,hole trajectory control,wellbore integrity evaluation,etc,to provide a model or reference for the drilling technologies of other shale gas fields.Furthermore,on the basis of ＂stable production and efficiency improvement,acceleration and cost reduction＂,the technology required by the further drilling of Fuling Shale Gas Field were proposed,and pertinent suggestions on drilling technology development were put forward to continuously improve the level of drilling technology in the Fuling Shale Gas Field.
