Each step is highly complex due to the dynamics of the process and the microscopic and macroscopic scales present mainly in the porous medium. The diagram corresponds to an onshore production system.

The fluid transportation from the reservoir to the surface facilities is commonly divided into three stages, as shown in the 2D schematic representation of Figure 1: recovery, lifting and gathering. The integrated and optimized management of operation and production processes is strategic to the advancement of the oil sector due to the vast and growing technological tools and the great challenges, such as fluid transportation, under many adverse conditions.

Los resultados obtenidos para el problema no isotГ©rmico muestran que el tipo de aislamiento es muy importante para garantizar que el intercambio de calor entre el petrГіleo caliente y el medio externo mГЎs frГo permanezca en niveles adecuados, de forma a que el transporte de fluidos en las secciones extensas de la tuberГa no comprometan la operaciГіn del sistema.

La tuberГa es aislada en toda su extensiГіn y la influencia del tipo de material del aislamiento que la recubre, asГ como la utilizaciГіn de una bomba para impulsar el fluido, es estudiado mediante el software unidimensional Pipesim В® para condiciГіn de presiГіn prescrita en la salida. La segunda secciГіn pasa por el lecho de un rГo, estando expuesta a un intercambio de calor mГЎs intenso. La primera y tercera se apoyan directamente sobre el suelo, intercambiando calor con el aire externo. Esta tuberГa, de 3600 m y 4 pulgadas de diГЎmetro, es formada por tres secciones. La tuberГa transporta petrГіleo desde una estaciГіn de colecta (que recibe la producciГіn de varios pozos) hasta un centro de almacenamiento. La dependencia de la viscosidad con la temperatura y el grado API del petrГіleo siendo transportado es introducida por la correlaciГіn de Hossain. La correlaciГіn de Dukler es utilizada para modelar la presencia de mГЎs de una fases de fluidos. En este artГculo se presenta el modelamiento matemГЎtico y numГ©rico del flujo bifГЎsico en una tuberГa terrestre parcialmente inmersa en un rГo. Las herramientas computacionales para la simulaciГіn numГ©rica del flujo bifГЎsico en tuberГas son importantes para determinar la viabilidad tГ©cnica de producciГіn de campos de petrГіleo. Keywords: Heat exchange, oil pipeline, two-phase flow, pressure drop, Pipesim. The results, of this 1D and non-isothermal problem with prescribed outlet pressure, show that the use of isolation when appropriately designed in terms of material quality and thickness is of utmost importance to maintain the heat transfer at low levels, in order to ensure the movement of fluids in long sections without compromising the system operation. The influence on the type of pipe insulation in the pressure and temperature gradients was analyzed with the aid of commercial 1D software Pipesim В®. The intermediate section is sitting on the river bed and is the critical part of the pipeline, once high heat losses are observed. The first and third sections are above ground and are in contact with the external environment.

The pipeline, of 3,600 m and 4 inches (10.16 cm) in diameter, transports the oil from a collecting station to a storage center and consists of three sections. The oil's viscosity is regarded as dependent on the temperature and on the API density of the oil by means of the Hossain correlation. The biphasic behavior of the heavy oil of 13,2 вЉPI is translated by the Dukler correlation. The present article presents the mathematical and numerical modeling of the oil biphasic flow in a partially submerged onshore pipeline. Д¬omputational tools for simulation of multiphase flow in oil pipelines are of great importance for the determination of the technical feasibility of the production in oilfields.
