Abstract

Drilling mud circulation is performed by means of positive piston-type mud pumps which cause nonuniform flow in the drill column. Fluctuations of circulation rate and mud pressure result in increasing the dynamics of the drilling tool, early wear and operating trouble of the drill bit, reservoir depressurization, unstable running and breakdowns of downhole drilling motors, operating life reduction of pump components. Delivery line is under the influence of high pressure with a significant value of its fluctuation which causes negative consequences. The paper is devoted to the developed downhole hydromechanical compensator of pressure fluctuation of circulating fluid mounted into the assembly of drilling string bottom. Moreover, it focuses on the description of the laboratory bench for testing the compensator and the obtained results
