DOWNHOLE GAS COMPRESSION SEPARATOR ASSEMBLY

摘要

Downhole Electric Submersible Pumps (ESP) in a production string often experience gas lock caused by free gas present in the production liquids which reduces intake pressure below the operating parameters of the ESP. A gas compression separator assembly, having a series of compressors and separation chambers, entrains or dissolves the free gas component of the production fluid and separates free gas for downhole disposal. The production fluid fed to the ESP intake has an increased fluid pressure, a reduced volumetric fluid flow, and a lower free gas content, and is less likely to induce gas lock of the ESP.

主权项

1. A method to produce fluid from a subterranean well having a production string positioned downhole in a wellbore extending through a formation, the method comprising the steps of:
(a) flowing production fluid from the formation through an interior passageway defined in the production string, the production fluid having a free gas component and a liquid component; (b) allowing uninterrupted production fluid flow through a gas compression separator assembly positioned along the production string while:
compressing the production fluid in the production string;separating at least some free gas from the production liquid; and (c) flowing the compressed production fluid to the intake of an ESP.
