Abstract
This relates to a gas separator ( ) of the cascade type, with stratified or non-stratified flow, equipped with automatic level control to perform a process of the gravitational separation of two immiscible fluids of different densities, particularly to separate the gaseous phase from a two-phase mixture (liquid and gas). It is installed at the bottom of an oil well, upstream from a lifting pump ( ) in order to minimize the entry of gas into pump ( ). The level control system comprises a valve ( ), a spring ( ) and a packer ( ). It is based on the combined effects of the abovementioned components ( ), the gas pressure on the region of perforated casing ( ) and the thrust exerted on a settling vessel ( ) by the liquid on which it floats. The separator according to the invention has a control system for the level of the liquid stored in settling vessel ( ) mounted within its separator ( ), ensuring flow of the mixture which is ideal for the occurrence of gas separation.
