Gas lift valve applied in gas lift mandrel mandrel, selective and lifting system for gas lift

摘要

Gas lift valve applied in gas lift mandrel mandrel, selective and lifting system for gas lift. The present invention describes a gas lift valve applied in chuck for lifting fluid hydrocarbons in reservoirs, gas lift mandrel selective and, finally, a lifting system for gas lift.Still, the valve of gas lift mandrel allows the process to be applied in the segregation of flow to the fluid, more specifically, the valve allows circulation of liquid and gas in the maximum possible flows, reducing the times of probe and allowing cleaning of columns more Effective during the workovers.The present invention is situated in the fields of oil industry and petroleum engineering.
