The Way of Appraising the Active Degree of Gas Reservoir Considering the Production Performance of Water Invasion Gas Reservoir

The water of body multiple factors calculated by static state and dynamical methods are the simplest ways to distinguish the active degree of water driver gas reservoir recently. However, the active degree of water driver gas reservoir is different in different production stage due to the influence of water body porosity and permeability, the formation communication of water body and gas reservoir, the production position, the well pattern deploying, and the gas well mode, etc. This paper develop a new way to distinguish the active degree of water driver gas reservoir which consider the production performance of water invasion gas reservoir, such as water body porosity and permeability, the formation communication of water body and gas reservoir, the production position, etc.
