Abstract

Claims (18)

1. An assembly for use in a drill string, the assembly comprising:

a Moineau motor comprising a rotor and a stator;

a rotary component and a stationary component for generating fluid pressure pulses, the rotary component and stationary component each comprising respective ports, the rotary component being drivable by the rotor;

the rotary component, stationary component, and rotor each comprising a bore defining a substantially continuous passage permitting a first route for fluid flow in an axial direction through the assembly;

the motor and the ports of the rotary component and stationary component providing a passage permitting a second route for fluid flow in the axial direction through the assembly, wherein the passage through the motor is between the rotor and the stator;

wherein fluid is divertable from the first route to the second route by blockage of the continuous passage.

2. The assembly of claim 1 , further comprising a seat for receiving a projectile for blockage of the rotor bore.

3. The assembly of claim 2 , wherein the seat is disposed at a first end of the rotor.

4. The assembly of claim 3 , wherein the seat is provided directly at the first end of the rotor.

5. The assembly of claim 3 , further comprising a funnel for directing the projectile to the seat.

6. The assembly of claim 5 , wherein the funnel comprises ports for fluid flow therethrough.

7. The assembly of claim 6 , wherein the second route includes the ports of the funnel.

8. The assembly of claim 3 , wherein the rotary component is disposed at a second end of the rotor.

9. The assembly of claim 8 , wherein the rotary component is directly connected to the second end of the rotor.

10. The assembly of claim 3 , wherein the rotary component is connected to the second end of the rotor by a drive shaft, the substantially continuous passage comprising the drive shaft.

11. The assembly of claim 1 , further comprising an oscillating unit.

12. The assembly of claim 11 , wherein the oscillating unit is configured to be driven by the fluid pressure pulses.

13. A drilling string comprising a plurality of the assemblies of claim 1 .
