... ofthe bit, reducing the lifetime of surface and downhole drilling equipment. The article reveals the influence of uneven pressure of flushing fluid to the drilling process, provides analytical researchof working of the designed downhole hydro-mechanical compensator of pressure fluctuations of the flushing fluid, installed in the bottomhole assembly. Materials and methods In order to solve the tasks wereused the basic laws of theoretical mechanics, fluid mechanics, analytical and experimental methods....

... technology requires steady circulation of the drilling mud. The article is devoted to the influence of pressure fluctuation of drilling fluid on working of the boring tool while drilling wells and evaluation of its quantity. The paper provides designed compensator which allowind to damp fluctuation of the stream. Materials and methods Investigation of the influence of pressure Results A technical solution for decreasing of amplitude of pressure fluctuation of drilling fluid is suggested. Сonclusions ...
