Abstract:

Study on Calculation of Water Inflow Rate of Bottom Hole of Gas Well With Water A new model for calculation of water inflow rate at bottom hole of gas producing wells is presented. The slippage effect of two phase and the transition mechanisms among different flow patterns are taken into consideration. The wellbore is divided into a number of segments whose pressure drop and space distribution of gas-liquid with time under unsteady-state flow conditions is calculated iteratively by using transient steady flow method. At last, the relationships of bottom-hole pressure and water inflow rate changing with time are established.
