PROCEDURE FOR DOUBLE-PHASE WELL FLUID PUMPING OUT AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS)

摘要

FIELD: oil and gas production. ^ SUBSTANCE: device for pumping out fluid containing gaseous and liquid components consists of pump for oil and gas producing well operation. The pump contains rotors and diffusers with internal and external sections. Central sections of rotors have channels supplying liquid. In the external section there are arranged turbine blades for gas compression. The sections are divided with a cylinder wall. The central and external sections synchronously rotate on a driven shaft. ^ EFFECT: raised efficiency. ^ 18 cl, 9 dwg
