METHOD FOR OPERATION OF PUMP-EJECTOR WELL JET INSTALLATION WITH HYDRO-DYNAMICAL PULSER FOR PRODUCTION OF HIGH-VISCOSITY OIL

摘要

A method for operation of pump-ejector well pulse unit for production of high-viscosity oils includes supply of active liquid medium by production string to nozzle of jet apparatus. After that one pumps out with jet apparatus passive medium. Before that one closes supply channels. After that one brings packer to transportation position with replacement of insert. Then one pumps out passive medium. At that supply of active liquid medium is carried out through surface aerator of ejector type. After that separation into two flows takes place and pumping out of passive medium treated with cavitation field.
