Slipen'kiy V. Parameters of hydrodynamic strengthener of axleloading for the rotatory well-drilling are grounding

Dissertation work is devoted the calculation of structural and power parameters of hydrodynamic strengthener of axleloading, origin and frequent reflection of hy-dropercussion wave based on realization of processes in а nonmonolith pipeline with the reserved cavity in an aggregate with work of point stream of washing liquid. During analytical researches mathematical models are offered motions of elements of distributive knot on the separate phases of duty cycle, which allow to forecast the power parameters and power description of hydrodynamic device. Researches of ex-perimental standard on а stand confirmed adequacy of mathematical and physical models of hydrodynamic device. Dependences of the dynamic loading are investigational on the productivity of boring pump, reflectivities and fading of hydropercussion wave. It is set that for providing а hydrodynamic device required technological regulation of axleloading size it is necessary, that attitude of diameter of borings pipes toward the diameter of working not exceed 0,5, and length of working chamber must not exceed 1,5 - 2,0 mcodes; Stand and experimentally-industrial verification of capacity and efficiency of new device rotined that the construction of hydrodynamic strengthener of axleloading is capable of working and can be used for the rotatory well-drilling without the reconstruction of the system of washing of the boring setting. Application of hydrodynamic strengthener allows to increase mechanical speed of the boring drilling in the of soft breeds on the average in 1,35 - 1,75 time. Expected economic effekt from application of hydrodynamik strengthener 1477575 grn. Makes on the enterprises of KP "Yuzhukrgeologia" in a year.
