Calculation of Parameters of Technological Equipment of Hydraulic Elevator Installation for Removing Sand Plugs from Wells

The paper considers the technological scheme of hydraulic elevator installation, according to which water from a pressure tank is supplied by working pump well through two parallel pipelines: monitor with washing nozzle for destroying sand plug and supply pipeline that connected containing suction pipelines taking slurry cleaning single- double-column wells plugs methodology calculation selection parameters equipment installation given. Based on compiled equations fluid motion along an active monitoring scouring nozzle, expressions have been obtained constructing characteristics these pipelines. A graphic-analytical method proposed determining flow rates in them finding coordinates operating point. By varying pump, without changing jet pump-hydraulic elevator, values useful lifting height were calculated, has made it possible select options (for polypropylene steel pipes) removing maximum depth 50 75 m.
