水平井一趟钻变径稳定器的研制与应用

摘要

长庆油田部分区域钻井施工周期短、一趟钻技术能够明显减少钻井周期，提高施工效率。介绍了研制的水平井一趟钻变径稳定器的工作原理和现场应用情况。分析了目前投阀型、排量型、电传控制型3种型号控制机构的优缺点，并提出了变径稳定器的发展方向。%Changqing oil field part area drilling cycle is short,“one trip drilling”technology can re-duce drilling period significantly,improving operation efficiency.An introduction is made for“one trip drilling”tapered stabilizer principles and field application developed by Changqing general drilling company,which will be used in horizontal wells.The advantages and disadvantages of three models are analyzed,and tapered stabilizer development direction is proposed as well.
