发明名称 Fluid conveyed thruster
摘要 A fluid conveyed thruster for use in combination with a bottom hole assembly connected to a drill string during drilling operations. The fluid conveyed thruster comprises a continuous passage comprising a narrowed portion and an intersection. Fluid passing through the continuous passage of the fluid conveyed thruster accelerates as it passes through the narrowed portion and the intersection. The acceleration of fluid exiting the fluid conveyed thruster urges the tool forward and in turn urges the bottom hole assembly forward within a wellbore. The fluid conveyed thruster extends the reach of the bottom hole assembly and the drill string within the wellbore.
