Study of Optimization Method for Variable-Density Completion of Horizontal Well
Abstract:
Based on Landman variable density perforation model, a horizontal well variable-density completion coupling model is derived under non-homogeneous formation conditions. And an actual well is taken for example to calculate the production fluid profile of horizontal well under different perforation densities. The results show that the production fluid profile of the high and low permeability section tends to be even with the decrease of the perforation density of the high-permeability section. Based on the coupling model, optimization methods for the variable-density completion of horizontal well under uneven stratum conditions are put forward. The production fluid profiles of optimized perforation model, actual perforation model, and even perforation model are compared. According to the results, the horizontal well corresponding to the optimized perforation model is with the most balanced inflow profile.
