ROP Improvement Technology for Horizontal Shale Oil Wells in Daqing Oilfield

  • 摘要:

    针对大庆油田古龙区块页岩油水平井钻井过程中存在井壁易失稳、摩阻扭矩大和钻井周期长等技术难点,以大庆页岩油高效快速开发为目的,分析了该区块地层特点和钻井施工难点,优化了三开井身结构,确保页岩目的层施工安全;根据实钻经验及现有技术水平,对井眼轨道进行优化,降低施工难度;针对二开直井段缩径、三开造斜段和水平段钻井周期长等问题,进行了井壁修整工具、旋冲螺杆钻井工具、清砂接头和水力振荡器等工具研究,并进行了钻井参数优化,形成了大庆油田页岩油水平井钻井提速技术。该技术在大庆油田古龙区块3口页岩油水平井进行了现场试验,平均完钻井深4 691 m,平均机械钻速19.03 m/h,机械钻速提高53.7%,平均钻井周期35.23 d。研究与现场试验表明,大庆油田页岩油水平井钻井提速技术可为大庆油田页岩油高效开发提供技术支撑。
