Calculation of Fluid Flow in the Oil Well under the Action of Powder Gas Generator

A numerical algorithm is developed, and the parameters of fluid flow in the oil well under the action of powder charge are calculated. For different combustion conditions, the dependence of gas pressure on the time and the maximum amplitude of fluid rise are found. The value is obtained for decreasing the pressure in the well relative to the hydrostatic pressure in the stratum; the hydrostatic pressure arises in cooling down the gases to the ambient temperature.
