The difficulty of extracting oil from great depths due to the huge amounts sand, water and other impurities has led fact that well jet pumps are becoming more common. Their use in production is facilitated by such factors as practical insensitivity content gas dissolved compared types pumps; simplicity design absence moving parts, which inherent all technology. reliability durability an order magnitude higher than those any used production. Obtaining excellent characteristics a pump requires systematic approach analysis modeling flow. Pumping complex task because there fairly large variety substances can be included it various fields. This leads problems when operation using fluid flow models rheological cavitation. complication mathematical provokes increase errors, complications verification finding rational coefficients corrections turbulence models. In paper, energy parameters improved calculation. A for pumping been designed numerical calculations have carried out with different aggregate states media. kinematic obtained efficiency calculated. As result calculation model cavitation, was 10 %, 3 times without increased consistent asymptotic methods calculating characteristics.
