Acoustic Artificial Lift System For Gas Production Well Deliquification

摘要

An artificial lift system and method for deliquification of gas production wells is provided. The artificial lift system comprises a downhole tool suspended by a power conductive cable in a wellbore. The downhole tool comprises an atomizing chamber for conversion of the liquid into droplets having an average diameter less than or equal to 10,000 microns. Natural gas produced by a producing zone of the subterranean reservoir transports the vaporized liquid molecules to the well surface. In operation, the atomizing chamber is located above the liquid column in the wellbore.

1. A method for artificial lift deliquification of production wells, the method comprising:
providing a wellbore that receives reservoir fluids from a producing zone of a subterranean reservoir, the reservoir fluids comprising gas and liquid, wherein the liquid comprise hydrocarbon, water and mixtures thereof in a liquid column at the bottom of the wellbore; providing a production tubing or a casing in the wellbore, wherein the production tubing or casing has a plurality of perforations for gas to flow from the reservoir up the production tubing or casing for subsequent recovery; providing a downhole tool comprising an atomizing chamber down a production tubing or a casing in the wellbore for conversion of the liquid into droplets for transport out of the wellbore by the gas flow up the production tubing or casing; wherein the atomizing chamber is in fluid communication with the liquid in the wellbore and wherein the atomizing chamber is located above the liquid column.
