涪陵页岩气田钻井技术难点及对策

Drilling Technology Challenges and Resolutions in Fuling Shale Gas Field

  • 摘要: 涪陵页岩气田是我国第一个投入商业化开发的页岩气田,其地表和地下地质情况均十分复杂,与常规油气藏和国外页岩气田相比,其开发过程中钻井施工难度较大。根据大量翔实的资料,从井壁稳定、轨迹控制、固完井质量以及降本增效等方面论述了涪陵地区页岩气田钻井工程中存在的主要技术难点,并对其主要原因进行了分析。在此基础上,针对性地提出了解决上述钻井技术难点的技术思路和方法,并在涪陵地区页岩气钻井技术研究成果的基础上,指出下一步应深化钻井地质特征精细描述、开展三维井眼轨道优化设计及控制、强化钻井提速技术攻关、完善钻井液与完井工艺配套等研究,以持续提高涪陵页岩气田的钻井效益。

     

    Abstract: Fuling shale gas field is the first commercial shale gas development region in China,where the surface and underground geological conditions are complicated.Therefore,drilling operations are more challenging than conventional reservoirs and than those shale gas fields abroad.Based on a lot of information available in Fuling Area,main challenges were analyzed in shale gas drilling.Then,some technical solutions and methods were proposed against such challenges.Moreover,considering the current achievements in shale gas development in Fuling Area,suggestions were put forward to further research to improve the drilling efficiency.These suggestions include fine geological characterization,3D optimized design and control of trajectory,research on enhanced drilling rate,and improved matching of drilling fluid and completion techniques.
