摘要： A powered reamer comprising a stationary assembly having a flow bore therethrough. A rotating assembly is disposed about the stationary assembly and one or more cutting structures are coupled to an outer surface of the rotating assembly. A flow restriction is disposed within the flow bore so as to divert a portion of fluid flowing through the flow bore through an outlet from the flow bore into an annulus between the stationary assembly and the rotating assembly. A power section is formed in the annulus between the stationary assembly and the rotating assembly. The power section operates to eccentrically rotate the rotating assembly about the stationary assembly in response to fluid flowing through the annulus between the stationary assembly and the rotating assembly.

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.
