Drift-Flux Modeling of Two-Phase Flow During Managed Pressure Drilling in Deep-Water Horizontal Well

EasyChair Preprint 13458

Abstract

Managed pressure drilling (MPD) is a sophisticated drilling method that allows precise control of the annular pressure profile throughout the wellbore. This technique is particularly valuable in deep-water horizontal wells, where the challenges of two-phase flow management are significant. This paper presents the development of a drift-flux model to describe the two-phase flow behavior during MPD operations in deep-water horizontal wells. The model accounts for the complexities of gas-liquid interactions, incorporating factors such as slip velocity and phase distribution. Results from simulations using the developed model are discussed, highlighting the impact of various operational parameters on flow dynamics. The findings underscore the model's capability to enhance the predictability and stability of MPD in challenging deep-water environments.
