Zastosowanie metody bilansu masowego w eksploatacji złóż gazu ziemnego w warunkach dynamicznych
(2008) Rybicki, Czesław; Blicharski, Jacek
In many cases of the reservoirs or underground gas storages production exist technical hindrances of closing of wells in time to permit the authoritative measurement of static pressures both at head and bottom of wells. A because important problem in reservoir engineering is the qualification of these pressures, necessary for the verification of resources of gas, from the values of dynamic pressures. Presented paper introduces just the method of marking of average pressures in the reservoir on the ground measured dynamic pressures in the well. This method is based on using of the terminal solution of gas inflow to the well in semi steady state. On the base of the dynamic pressures measurement in production wells one marked values of average pressures in the reservoir and then with the method 'p/z' one executed estimations of energy conditions of analyzed reservoir of the gas and one marked initial resources of gas in zones of influencing of well. Obtained results were verified executing alternative balance calculations basing on measurement of bottom pressures in static conditions. From comparing results the full usefulness of the method.
