La détermination exacte du modèle mathématique de la pression en tète de puits dépend du calcul plus précis de la résistance hydraulique. Cette étude présente une expression mathématique exprimant entre la résistance hydraulique et le nombre de Reyno [...]
Dans la conception et le contrôle hydrauliques des programmes de forage, l'exigence fondamentale est le calcul précis des composantes de la résistance hydraulique des boues de forage lors de leur écoulement en régime turbulent. Cependant, dans la pra [...]
This study aims to develop a mathematical analysis for one-dimensional modeling of a radial flow through a production well drilled in a confined aquifer, in the case of steady-state flow conditions. An analytical solution has derived from that expre [...]
