A method of manufacturing a thick walled Moineau-style stator entails drawing a thick walled tube through rotatable internal and external dies to form a helical outer profile including crests and through on the tube. The tube initially has one end with a diameter smaller than the others, with the smaller diameter end being inserted between the inner and outer dies, where it is seized and drawn through the dies.

A telemetry system and method for communicating information axially along a drill string comprised of a drive train supported within a housing. The system includes an axial conducting loop formed by the drill string for conducting an axial electrical signal embodying the information between a first axial position and a second axial position in the drill string, which axial conducting loop extends between the first and second axial positions. A transmitter transmits information to the axial conducting loop. The drive train includes a downhole end which extends from and is located below the housing. At least one of the first and second axial positions is located in the downhole end. The method includes the step of conducting the axial electrical signal between the first and second axial positions through the axial conducting loop which extends between the first and second axial positions.

An embodiment of the apparatus includes a housing having a first flow bore and a second flow bore, the first flow bore having a drilling fluid flowing therein, a device disposed in the second flow bore to receive a fluid flow, and a diverter disposed between the first and second flow bores, the diverter having a first position preventing the drilling fluid from flowing into the second flow bore and a second position allowing a portion of the drilling fluid to flow into the second flow bore and through the device. Another embodiment includes a variable second position directing the drilling fluid into the second flow bore at a variable flow rate. A further embodiment includes a drill collar as the housing and a power generation assembly as the device to receive the fluid flow. Embodiments of a method of diverting a fluid flow in a downhole tool include diverting a portion of a first fluid flow to a second flow bore, and further varying a flow rate of the fluid to the second flow bore.

A hollow stator for a Moineau-style motor is constructed from a composite material such as fiberglass or graphite. A series of lobes arranged along its inner surface corresponds to the external lobes of a rotor inserted in the stator, and enables use of a constant width elastomer layer between the stator and the rotor. The composite stator includes a pair of box socket interface members at its ends to enable the stator to be attached to other components such as pipeline sections.

A thick walled Moineau-style stator and method of manufacture are disclosed. The outer profile of the stator follows the inner helical profile of the stator. The application of an elastomeric layer to the inner profile of the stator results in a constant thickness for the elastomeric layer and proximity for the walls of the stator. This improves the durability of the motor because of lower heat generation and better heat dissipation. The stator walls also support the elastomeric layer. Further, the thick walls of the preferred stator eliminate the need for additional drill piping or other support provided adjacent the stator. Thus, the cost of additional piping and difficulties placing a stator inside drill pipe or drill string housing are eliminated. Further, the improved strength of thick wall steel when contrasted to a thin wall counterpart allows a higher operating pressure drop for a given stator length, resulting in a higher power output. Moreover, the undulating outer profile of the stator provides a distinctive appearance to the stator piping.
