Systematic Evaluation Method of Water Aquifer Energy for Water-Drive Gas Reservoir

On the basis of present relevant research about water aquifer energy for water-drive gas reservoir, systematic evaluation method of water aquifer energy for water-drive gas reservoir is constructed from water invasion recognition, water aquifer size calculation, water influx volume calculation, water aquifer active degree evaluation and drive energy composition analysis. According to static and dynamic data of an actual typical water-drive gas reservoir, water aquifer energy was evaluated systematically. Research results indicated that this method can evaluate water aquifer energy of water-drive gas reservoir quickly and systematically, which can offer reference to development performance forecast and development adjustment of this kind of gas reservoir, and realize reasonable and effective development of this kind of gas reservoir.
