Hydrodynamic Bases for Calculating the Motion of Two-Phase Systems in Complex Pipelines

Abstract

Considering the conditions for the development of an oil field for different layers, the pipeline networks are different. Based on hydromechanics of homogenous fluid and gas, a new model of two-phase systems movement of fluid-gas type in horizontal tubes is suggested and the major calculation formula for complicated pipelines is developed. In constructing a complex system of pipelines transporting both single-phase and two-phase systems, firstly, it is necessary to consider the location of wells in the field, their initial and final flow rates, as well as the physicochemical properties. This method enables us to define the main parameters of complicated pipelines, considering the physical properties of two-phase systems. The equation of two-phase systems movement in simple and complicated pipelines, allowing recommending using this approach in field experience, is obtained as well. Keywords: shear stress, complicated pipeline, multiple connections, diameter, volumetric fluid, and gas discharge.
