Supply in periodic well at high gas saturation of reservoir oil

Key words: oil reservoir, well, cycling, gas content, coefficient of productivity, bottom-hole pressure, reservoir pressure.

The dynamics of changes in the coefficient of productivity into the well under the regime of periodic pumping. Work well with periodic high gas saturation and reservoir oil at low bottom-hole pressures is complicated by the significant release of the free phase, dissolved gas, which is reflected in the ratio of the flow and well productivity.
