Abstract:In this paper, the simulation models of constant-volume closed overpressure gas reservoirs and water drive overpressure gas reservoirs were constructed basing on the pressure drop equations and the productivity equations, according to the features of overpressure gas wells and reservoirs. With these models, the pressure distributions of static fluid and flowing fluid in borehole were calculated respectively. The pressure distribution in borehole and formation of overpressure gas wells was simulated with computer and mathematical model techniques, through which the distortion and the variation process with pressure drop of reservoir rocks and overpressure gas well pressure, temperature, outflow, flow pattern etc. were both vividly described. The software, \"Production Simulation System for Overpressure Gas Wells\", was designed, which laid a foundation of the optimal control for single overpressure gas well and offered a more efficient method for the description of the production performance of overpressure gas reservoirs. | |||
