摘要： A pulse generator comprises a stator coupled to a housing and a rotor that is rotatably disposed within the housing. An annulus is formed between the rotor and the stator. An inner bore is formed through the rotor. One or more outer flow ports provide fluid communication between the annulus and the inner bore. A retrievable valve assembly is rotationally coupled to the rotor and at least partially disposed within the inner bore. The retrievable valve assembly includes a rotary valve member having one or more primary flow ports. A fluid flow path is periodically formed by the one or more outer flow ports, the annulus, and the one or more primary flow ports as the rotor rotates.

摘要： A planetary gear box or drive (48) and arrangement of the gear box with a drive motor permits electrical, optical or other types of cabling or wiring to be passed through the planetary gear box along its axis of rotation. The planetary gear box drives or rotates, for example, a reel of coiled tubing (30). Electrical, hydraulic, optical and other types of line for lowering into a well bore through the coiled tubing is passed through a passageway through the center of the planetary gear box, into one end of a hub of the reel, and then into the coiled tubing, which is injected into the wellbore. The other end of the hub of the reel is able to be connected to a swivel joint that can be connected to a pump for pumping fluid into the coiled tubing.
