【 摘 要 】

Numerical modeling of eccentric mass rotation in fluid under different water and oil pressures is performed. The relationship of extra-consumed motor power to overcome fluid resistance in downhole operation of screw pump at the maximum design depth of n is obtained. The power consumption of vibration sources is evaluated in the productive field of low- and high-viscosity oil in Mongolia and Russia.
