Pressure controlling method for managed pressure drilling with supercritical carbon dioxide as the circulation fluid
Heat transfer along the wellbore was analyzed, and then a closed mathematical model, which fully couples the hydrostatic pressure, temperature, physical properties of CO2 and friction, was established to keep bottom-hole pressure constant during drilling process. Based on the pressure profile in wel...
