Аннотация: A mathematical model of the drilling mud flow in a removable rectilinear core barrel well is made up. The flow structure of in the well design elements was studied using numerical simulation. Pressure losses in the wellbore were analyzed. It was discovered that the main contribution to the pressure difference values is made by the Показать полностьюannular channel between the borehole walls and the drill pipes, as well as the crown bit.
