摘要
深井采用不同直径组合油管,常规柱塞举升不再适用该油管。提出了一种应用于上大下小组合油管柱的新型接力式柱塞气举装置。这种装置在结构上能够满足深井采用组合油管的要求,为深井柱塞排水采气与柱塞举升采油提供了一种新的思路。介绍了这种装置的结构、特点以及工作过程。
Considering the problem that different diameter combined tubing are adopted and con- ventional plunger lifting no longer applies in deep well, this paper presents a kind of new relaying type plunger gas-lift equipment applied to upper large down junior combined tubing. This kind of device could satisfy the require that deep well adopts combined tubing and supplies a new way for gas recovery by water drainage, and oil recovery with plunger lifting in deep well. Structure, characteristics and work process of the device is introduced as well.
