Application of Horizontal well Multiphase Steady State Flow Model to Evaluate Water Control Effect of ICD

Abstract

Because of reservoir heterogeneity around the horizontal section of horizontal well, which makes inflow profile and pressure drop unevenly distributed in horizontal section. It is easy to cause water coning in reservoirs with bottom aquifer and affect the ultimate recovery. With the development of horizontal-well drilling and completion technology, the demand of water control increases step by step. In this paper, we used the node analysis method to establish a wellbore multiphase steady state flow model based on the equivalent filtrational resistance principle, and compared two completions’ water control ability in a case study. Results show that this model can effectively assess the effect of water control in different completion methods, and ICD can give a better water control than slotted liner completion with packer. From our results, we provide a new theoretical reference to a better choice of water-control completion for horizontal wells applications.
