事故的发生在很大程度上制约着钻井速度,排除事故所耗费的时间占建进总时间的10％～20％。使用万能液力打捞器可以缩短排除事故的时间,降低建井成本。
The occurrence of the accident restricts the drilling speed to a large extent, and the time it takes to eliminate the accident accounts for 10% -20% of the total construction time. The use of universal hydraulic salvage can shorten the time to eliminate accidents and reduce the cost of well construction.
