钻具和套管的卡钻是降低钻进技术经济指标的基本原因之一。它们约占事故时间的80%。如果每年在消除其他类型事故的费用比例下降的话,那么在消除卡钻事故上的费用比例却在增加。比如,在乌克兰,这类事故时间从1980年1212个台时到1982年达到1398个台时。由于这一原因,必须创造用于消除 Drilling and drilling of the casing is one of the basic reasons for lowering the economic indicators of drilling technology. They account for about 80% of the accident time. If the proportion of the cost of eliminating other types of accidents is reduced every year, the proportion of the costs of eliminating stuck pipe accidents is on the increase. In Ukraine, for example, such accidents took place from 1,212 in 1980 to 1,398 in 1982. For this reason, it must be created for elimination
