Hydraulic calculation method for pipelines through which gas-liquid system moves

R.Kh. Askerov

Recently, oil and gas industry development shows that gas-oil mixture common transportation via single pipeline is one of the most efficient methods. Therefore, in this case there is no need for new pipelines and compressor stations construction. In the North Sea, in Canada, in West Siberia and other oil and gas regions in connection with gas prices growth mixed systems combined collecting and transportation is wide spread. This method at the same time is efficient from economical point of view. Many examples may be given on gas and condensate combined transportation via single pipeline in marine conditions. And with it, studying of two phases moving in horizontal pipe is live issue. Such moving is studied in theoretical and laboratory researches in the given article. Hydraulic calculations on existent pipeline have been carried out on this method and equilibrium of mixture movement on horizontal pipe is obtained. The calculations may be conducted via obtained methods for complex pipelines. The obtained results show the rightness of above mentioned methods and their usage in practice.
