生产过程中，一些抽油井的油管中会形成一个或两个特定的段塞气柱。在活塞上、下冲程中，段塞气往于特定的位置上交替出现，且在油管内液柱的作用下弹性伸缩，产生旋流、空蚀。热效应及呼吸等作用。最终造成油管丝和（公扣、母扣）之间刺槽、本体刮擦等，导致腐蚀加剧油管变薄刺漏而躺井。建议通过减少冲次、泵升级、提高丝扣的压紧系数、增加丝扣数量等方法解决该难题。 In the production process, some pumping wells will form one or two specific slug columns. In the piston, the next stroke, the slug gas to a specific location alternately appear, and in the tubing elastic column under the action of elastic columns, resulting in cyclone, cavitation. Thermal effects and breathing and other effects. Eventually resulting in tubing between the pipe and the (male buckle, female buckle) between the prick, scratch the body, leading to increased corrosion pipe thinning leakage and lying. It is suggested that this problem be solved by reducing the number of trips, pump upgrades, increasing the compression factor of the thread, and increasing the number of threads.
