摘要： An apparatus for use downhole is disclosed. The apparatus includes a downhole device and an actuation device that includes: a housing including an annular chamber configured to house a first fluid therein and a piston in the annular chamber that divides the annular chamber into a first section and a second section. The piston is to a biasing member. A control unit enables movement of the first fluid from the first section to the second section to supply a second fluid under pressure to the tool to move the tool into an active position and from the second section to the first section to stop the supply of the second fluid to the tool to cause the tool to move into an inactive position.

摘要： In general, the present invention provides a modular drilling assembly having a module for contactless power and data transfer over a nonconductive gap between rotating and non-rotating members of a steering module. The gap usually contains a non-conductive fluid, such as drilling fluid, or oil for operating hydraulic devices in the downhole tool. The downhole tool in one embodiment is a modular drilling assembly wherein a drive shaft is rotated by a downhill motor to rotate a drill bit attached to the bottom end of the drive shaft. A substantially non-rotating sleeve around the drive shaft includes at least one electrically-operated device. The drilling assembly is modular in that it includes at least one steering module at the bottom end of the drilling assembly that has at least one steering device module that provides power to the force application member. A power and data communication uphole of the steering module provides power to the steering module and data communication between the drilling assembly and the surface.

摘要： The present invention provides an electromagnetic telemetry apparatus and methods that include an insulating connector that comprises an outer metallic female member that has an inner conical longitudinal surface. In one embodiment, a tubular metallic male member is disposed in the female member, thereby crating an axial conical gap between the male and female members. A conical metallic sleeve having dimensions that substantially correspond to the axial conical gap is disposed in the axial conical gap. The outer tubular surface of the male member is coated with an insulating material, such as a ceramic material. A shoulder at one end of the male member prevents axial movement of the sleeve in one direction and a parallel key between the female member and a stabilizer member prevents rotational movement between the male and female members. The sleeve remains stationary relative to the insulated surface of the male member when the male and female members move longitudinally relative to each other. In an alternative embodiment, a double pin is connected between a lower section and an upper section. Insulation is provided at one end of the double pin. A loading sleeve disposed around the pin absorbs compressional stress and also electrically isolates the upper and lower sections.
