Studying of lifting procedure of fluids with mechanical impurities along a well bore by means of submerged pumps usage
The paper presents substantiation of usage of auger-drill catcher of solid particles, based on calculations accomplished by application of modern computer methods of hydro-gas-dynamics at some sector of a well bore and required for increasing between-repair time period of producing wells. The proposed construction of a auger-drill is described, the structure of inter-action of solid and liquid phases depending on an auger-drill size and fluid flow speed is studied.
