Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Due to the variation in pressure drawdown along a well, pressure drop can occur in a vertical well. Accurate prediction of the inflow performance for perforated vertical wells is of great significance to reservoir analysis and perforation optimization. Under steady‐state inflow, a reservoir/wellbore‐coupling model is proposed that combines a numerical reservoir model and a semianalytical wellbore model. One type of optimization problem is also established that considers the effects of perforation density on the productivity of a vertical well, for which the vertical‐well production is treated as an objective function. A number of experiments are presented demonstrating how the model could be used to obtain the optimum perforation distribution for infinite‐conductivity and finite‐conductivity wells.</p> </abstract>
