Abstract

 

The flow of oil and gas in the production pipelines is a crucial step for the oil industry, which always seeks to maximize the production of these valuable hydrocarbons. The modeling of the flow patterns allows a better analysis of the behavior of the mixture. In thiswork, the mechanical energy balance is applied to represent the multiphase oil-gas flowbeing evaluated; the contribution of the terms of kinetic energy and friction pressure dropalong the pipe. The simulation results of pressure drop profiles showed that the kinetic effects due to the inertia of the gas are equivalent to those from compressible flow by gas expansion. The friction can also be significant to the overall result of the pressure dropthat will depend on the flow pattern and contact conditions of the gas phase with the pipe wall.

 

Key words: Oil-gas flow, horizontal flow, kinetic effect, friction effect.
