斜井打捞解卡工艺技术优化研究

Research of Optimization for Fishing and Unstuck Tech in Cline Well

针对斜井打捞解卡作业受井况条件的限制,工艺参数需优化配置的问题,对倒扣作业工艺提出了一种易于判断和实施的方法;对套铣筒的长度选择研究了一个计算方法,并结合实际情况提出了优选原则。实例证明上述方法可以在确保安全的情况下,降低成本,节时省力,实现完全打捞。

Fishing job in cline well is confined by the well conditions, sot he parameters of fishing operation need optimized. A practical method on back-off job is sugg e sted which is easy to judge and conduct. A calculating method to determine mill sleeve length is presented and the optimizing principle is introduced combined w ith practice. Field examples prove that, on condition of safety, these methods a re economical and efficient, realize fully fishing.
