摘要
螺杆钻具抽筒事故是定向井、水平井钻井过程中的一种较为常见的钻具事故 ,打捞风险较大 ,成功率较低 ,多数情况下易出现填井侧钻的情形 ,文中详细介绍TK4 2 4CH侧钻短半径水平井 12 0螺杆钻具 3次抽筒成功打捞技术。
During drilling,the breaking screw accident is a usual drilling tools accident.Its fishing hazard is large,and success ratio is low.This paper introduces the cases of screw breaking in TK 424CH short-radius horizontal well and summarizes the successful fishing operation on 120 breaking screw in the well.
