INFLOW PERFORMANCE RELATIONSHIP (IPR) EQUATION FOR A DAMAGED WELL IN SOLUTION-GAS DRIVE PRODUCTION

摘要

We have analyzed Standing's equation for a damaged well and have identified its problems, and have taken them into account to develop a new inflow equation to predict productivity for a damaged well in solution-gas drive production. For comparison, we used both equations to calculate the inflow performance relationship (IPR) curves and have established that the calculation results are quite different. We have demonstrated the validity of the new equation. We have derived a formula for calculating the flow efficiency of the well.
