Hydrogas-dynamic exploration of the gas-liquid mixture flow in vertical lifting

The hydrodynamic flow of gas-liquid mixture was investigated in the vertical pipeline. It is confirmed by the existing experiment in technical references that to obtain theoretical work, taking into account B.A. Arkhangelsky`s theoretical basis dependence γfix/γl of friction is necessary. A new pressure gradient model tested in a great number of wells was chosen as well. Pressure losses for liquid and gas mediums are calculated by the Blazius formula, where the components in the mixture move in turbulent regime. The accuracy of the dependencies was verified using A.P Krylov`s experimental dependencies. A calculation method differ from A.P. Krylov`s has been developed. Via proposed method it was defined that each regime has its specific pressure gradient and there cannot be constant gradient for various regimes as A.P. Krylov shows.
