Effect Of Drawdown Pressure On Water Production In Gas Reservoir

The water production is widespread in the exploitation of gas reservoir. The drawdown pressure is the main force that drives the formation water. Based on the integration of relative permeability curve and mercury intrusion curve, the analysis of the effect of drawdown pressure on the water production is conducted. As shown by the research result, when the drawdown pressure is different, the water that starts to flow belongs to distinct category, and the water producing degree varies. Larger drawdown pressure results in higher water producing degree. If P-2更多
