Abstract. The article deals with issues connected a problem of the use of foams as flushing fluids when drilling oil and gas wells. The purpose of this article is estimate of possibilities to control parameters of gas-liquid flow in the processes of foam generation and foam reduction by mechanical influences. We considered two possible methods of control parameters of two-phase flow: blowing/suction of gas and the variation of channel geometry. The mathematical modeling was used as a tool of investigation. Calculation procedure was proposed based on the theory of onedimensional two-phase flows. Influence of the blowing/suction of the gas along the channel on the gas capacity and flow and friction at the wall were conducted. Influence of diameter channel vary on these parameters were conducted as well. The results of the study showed that the combined use of these effects can be an effective tool to control structure of gas-liquid flow. The obtained results are interesting to development of technical devices of foam generation and foam reduction in wells.
Keywords: control of gas-liquid flow, foam, mathematical modeling, gas capacity, friction.
