Onatsko R. Justification of rational operating modes for downhole jet pumps.

The thesis is devoted to questions of a heightening efficiency of use jet techniques at mining oil and gas deposits. In a thesis the generalized mathematical model of operation of the jet pump in system of circulation of well with direct local flushing out of working face designed on the basis simulation hydraulic links between devices jet systems which allows to develop a hydraulic analog of blending streams as system of potential jets an opposite direction that enables to expand field of analytical definition performances of jet pump on a gamut change of coefficient injection from 0 up to -1. It is established correlation between pressure of wash liquid on an input in well and expenditure of stream in a face contour of circulation as nonlinear extreme dependence which allows to realize a remote monitoring and operative regulation an operating mode of the jet pump.
