ABSTRACT = {Gas-liquid two-phase flow is ubiquitous in the process of oil and gas exploitation,
gathering and transportation. Flow pattern, liquid holdup and pressure drop are important
parameters in the process of gas-liquid two-phase flow, which are closely related to the
smooth passage of the two-phase fluid in the pipe section. Although Mukherjee, Barnea
and others have studied the conventional viscous gas-liquid two-phase flow for a long time
at home and abroad, the overall experimental scope is not comprehensive enough and
the early experimental conditions are limited. Therefore, there is still a lack of systematic
experimental research and wellbore pressure for gas-liquid two-phase flow under the
conditions of middle and high yield and high gas-liquid ratio in conventional viscosity,
and the prediction accuracy is low. In view of this, this study carried out targeted systematic
research, and from the flow pattern, liquid holdup and pressure drop aspects, established the
relevant model, obtained a set of inclined wellbore gas-liquid two-phase pipe flow dynamic
prediction method. At the same time, firstly, the model is tested by experimental data, and
then the model is compared and verified by a number of field measured wells, which proves
that the model is reliable and the prediction accuracy of wellbore pressure is high.},
