Abstract

Background Currently, associated petroleum gas utilization is an urgent task of the oil industry. The most cost-effective solution of the problem is widespread adoption of one-pipe oil collection system. This requires the transfer of existing pipelines to the mode of transport of gas-liquid mixtures (GLM) and selection of the appropriate pumping equipment, which in turn requires the new calculation methods of GLM transportation. An analysis of existing methods of calculation modes compared with the modes of pipelines operation requires the assess of these methods and identification of their further development. Aims and Objectives Reduction of the existing calculation formulas of the operating conditions of pipelines for GLM transportation to the unit arguments, their comparison, analysis of the results of calculations in comparison to the operating data outlines the further recommendations. Results Considering a number of methods for the calculation of operating modes of pipelines for transportation of GLM the authors reduced the existing formulas to the unit arguments. Calculations by the existing methods of the existing pipelines, comparison of the calculated results with the operating modes of pipelines provided the assessment of the accuracy of the considered methods. Finally, the recommendations for GLM pipeline transportation are given. Conclusion Currently available GLM pipeline transportation calculation methods do not provide the required accuracy in some cases and flow regimes. These cases must be considered in the future in the calculation methods.
