不压井作业设备引进技术研究

不压井作业设备是一种能在井筒内有压力、有油气的情况下不用压井就可以进行钻井或起下管柱作业的一种先进的新型井下作业装备。不压井作业设备解决了修井作业过程中由于压井工序带来的油层污染及产量下降问题；解决了注水井作业过程中，放喷影响注水实效．造成油藏泄压问题；特别是针对高压注水油藏．解决了注水井溢流太大无法作业的问题。它能有效缩短作业周期，从而提高生产效率．并能准确地反映地层的真实情况。

Technical survey on imported snubbing unit

Snubbing unit is a new equipment working in downhole at the conditions of inner pressure and oil and gas in well bore,drilling operation or the up-and -down operation.The unit solves the problems of formation pollution and production decreasing,the affection of injection discharge,pressure drop in reservoir and especially the impossibility of in high injection oilfield,It reduces the operation time effectively and shows real condition in down hole.
