摘要
CBX井是一口定向井,该井第一层测试作业结束后在注封隔水泥塞过程中,出现了88.9 mm钻杆被固住的复杂情况。经过采取原钻具倒扣和使用倒扣接头配合反扣钻杆带进行倒扣的处理对策,共打捞出钻杆3851.87 m,解除了复杂情况,满足了后续测试油作业要求。就本井复杂情况的处理对策进行了分析探讨,以期对以后类似的复杂情况处理提供借鉴。
CBX is a directional well. When setting the cementing plug after DST1, complicated situations occurred, the 88.9 mm drill pipes were sticked. Through a series of back-off operations using the original right-hand drill pipes and left-hand drill pipes con- nected with fishing spear, 3 851.07 m of drill pipes were fishing out. Not only complicated conditions were successfully removed, but also satisfying the requirements for later DST. In this paper, the disposal measures for the complicated conditions have been dis- cussed, which might provide be a reference for solving the similar problems in the future.
