The effect of gas velocity on the specification of inner diameter of production tubing

S.A. Isayeva - Azerbaijan State University of Oil and Industry

Based on the gas dynamics laws, the method of gas well calculation considering the solid particles in the flow is offered. The equation for the motion of gas with solid particles in various operation regimes of gas well is suggested. Obtained equations allow to specify the velocity of upwardly moving gas stream considering the rate of solid particles, to define the most optimum conditions for the extraction of particles in the borehole of gas well. The impact of the main parameters of gas well in the extraction process of solid phase has been considered. It should be noted that the improvement of gas motion process in lifting tubes is seen, however, in this respect, it is necessary to consider all technological parameters of well operation. In such cases, the regulation process considering wellhead pressure is essential. While changing the gas motion velocity, the extraction from the well borehole with definite flow rate is seen. The velocity increase may create significant additional pressure in the reservoir, which can break down the bottomhole zone.
