... устройства свидетельствуют о достоверности теоретических положений и высоко эффективности работы компенсатора. Drilling mud pump's operation is the main source of pressure fluctuations of flushing fluid during wells drilling. The pressure fluctuations lead to narrowing of the range of stableworking of downhole hydraulic motors, vibration, reducing the resistance ofthe bit, reducing the lifetime of surface and downhole ...

... амплитуду колебаний давления, идущих от забоя, на месте их возникновения. Abstract Wells drilling 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 ...
