Technology Applied Research On Reducing The Wellhead Back Pressure

This article describes the general situation of Intercampo norte oil production and oil pipelines of the basic ground ;Statistical analysis of the back pressure of high production wells, using a nodal analysis system determines a reasonable back pressure; on some of the constituents of heavy oil to experimental analysis and experimental gas chromatography analysis of saturated hydrocarbons , measurement of the heavy oil viscosity-temperature relationship , discusses the reservoir fluid viscosity, density, freezing point temperature and the nature of water and other fluids; calculated and discussed the influence of the fluid viscosity, density, velocity, water, gas production and other factors on oil gathering pipeline flow resistance; comprehensive analysis Common lower back pressure of the process methods and their adaptability to discuss countermeasures reduce back pressure and, based on Intercampo norte oil production wells with high back pressure situation, determine the appropriate back pressure down the field methods, focusing on Application of crude oil emulsion viscosity and viscosity oil soluble viscosity reducer technology, introduces the types of chemicals used and application characteristics; evaluation of viscosity by reducing screening test, were recommended by a water-soluble oil emulsion and oil-soluble viscosity reducer viscosity reducer.
