摘要
在有杆抽油系统中 ,为了防止油管偏磨及抽油杆断脱 ,研制了油管旋转器。它是借助游梁动力 ,利用蜗杆、蜗轮和棘轮等部件 ,驱使油管管柱做近似匀速转动 ,抽油杆接箍与油管内壁的接触面积扩大 ,使油管磨损均匀 ,因而在管内壁上也就不易磨出沟槽 ,以达到防止油管局部偏磨延长免修期的目的 ,同时延长了抽油泵的使用寿命 ,减少了油管结蜡。 5 0口井的应用情况表明 ,这种油管旋转器的防偏磨效果好 ,延长了生产周期 。
To prevent eccentric wear of tubing and fall-off of sucker rod, a tubing spinner is developed. In virtue of the power of the walking beam, it drives the tubing string rotating uniformly by means of the worm screw and worm wheel and ratchet wheel, thereby prevents the local eccentric wear of the tubing. Use in 50 wells shows that, this tubing spinner has good effect in service, and can extend the production period of oil wells obviously.
