Choice of method for determining pressure losses
during multiphase flow in vertical wells E.N. Aliyev, T.S. Babayeva
This article examines the selection of a method for
determining pressure losses during multiphase flow in vertical wells. An
analysis of methods used to determine pressure losses during vertical
multiphase flow (Hagedorn-Brown, Beggs-Brill, Orkishevsky) is conducted for
parameters that vary during well operation. It is demonstrated that the
Hagedorn-Brown method provides the best results for small pipe diameters (3.5
inches) and low gas-oil ratios (611–938 SCF/STB), while the Orkishevsky method
is preferable for larger pipe diameters (4.5 inches) and high gas-oil ratios
(938–1898 SCF/STB).
