On the base of combined finite element - difference method, we carried out computer modeling of the filling process of gas cap of geosoliton field. According to obtained data analysis, filling process of the gas cap essentially depends on filtration parameters of considering porous reservoir, its size and characteristic fiches of the filling origins. Filling gas cap velocity mainly determined by origins power and less depends on their sizes and quantity. At the case of equal power origins, the filling gas cap velocity is proportional to the power of these origins. At the case, when different power origins act, the filling gas cap process passes irregularly. At the initial stages of filling process, excess pressure reservoir places closely correlate with origins installation. In the subsequent stages of filling, the pressure gradually aligns in all reservoir places and then regularly increases. As calculations show, regular filling of all gas cap region comes approximately over one hundred years since beginning of the process.
