The Prediction of Pressure, Temperature, Velocity, and Density of Two-phase Flow in Shut-in Procedures for the HTHP Gas Wells

摘要

A coupled system model of differential equations of pressure, temperature, velocity, and density of two-phase How in shut-in procedures in HTHP gas wells is examined. The basic data of X Well in Sichuan, China, is used for case calculations. Fluid pressure, temperature, velocity, and density curve graphs along the depth of the well are plotted at different times.
