摘要： A system and method to control fluid flow to downhole tools and equipment, and to allow formation testing and sampling operations is disclosed. The system includes an actuator assembly that may be mechanically or electrically activated to operate a flow diverter assembly. The flow diverter assembly may divert fluid flow to the annulus of the wellbore, to the stator of a power section, through a by-pass bore in a rotor of the power section, or any combination thereof. In the mechanically actuated actuator assembly, the actuator assembly is activated by pressure changes in the fluid introduced by cycling the pumps at the surface; and in the electrically actuated actuator assembly, the actuator assembly is activated by downlinks sent from a surface control unit or computer at the surface.
