近几年来塔河油田在直井段快速钻进中大力推广“PDC钻头+直螺杆”快速钻进技术,本技术在塔河油田钻井施工难度较大的托普区块得到了充分的应用,对加快钻井周期、节约钻井成本取得很大成效,根据塔里木胜利钻井公司70120队2010年来有关实践,结合理论分析,对PDC钻头及钻具的选择,泥浆转型等进行了总结探讨,对今后直井、水平井的快速钻进具有一定的指导意义。
In recent years, Tahe Oilfield vigorously promotes “PDC Bit + Straight Screw” rapid drilling technology in the rapid drilling of straight well sections. This technology has been fully applied in the top block where drilling is difficult in Tahe Oilfield According to the related practice of 70120 Team of Tarim Victory Drilling Company in 2010, combined with theoretical analysis, the paper summarized the selection of PDC bit and drilling tool, mud transformation and so on. In the future, The rapid drilling of horizontal wells has some guiding significance.
