Numerical simulation of gas-liquid two-phase flow in wellbore based on drift flux model

作者：

Highlights：

• A fast computational code for gas-liquid two-phase flow in wellbore was developed by AUSMV scheme.

• The simulation results of numerical test cases agreed well with the references.

• The simulation of gas-kick reflected the dynamic changes of the parameters of fluid in process of gas rise from well bottom up to the wellhead.
