Combination of Acid, Gas and Drilling Fluid Flow Multiphase Flow Behavior in Vertical Wellbore

EasyChair Preprint 9957

Abstract

For the hydraulic parameter design and wellbore pressure management in acid gas field drillings, the transition laws of multiphase flow in a wellbore during acid-gas mixture input are crucial. It can be complicated and difficult to appropriately predict the behavior of multiphase flow for an acid-gas combination and drilling fluid flow in a vertical wellbore. But there are some broad conclusions that may be drawn. A precise wellbore temperature and pressure are required for the acid-gas mixture to be in the supercritical phase, which results in drastic changes to the mixture's physical properties near to the critical point, claims the research. Additionally, the supercritical-liquid two phase flow, liquid-liquid two phase flow, liquid-liquid two phase flow, and gas-liquid two phase flow are all possible passageways for the multiphase flow in turn as the combined fluids rise from the bottom hole to the wellhead. Methods for calculating friction factors, drift flux models, and flow transition criteria have all been offered for this type of multiphase flow.
