    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.

    摘要： An apparatus for measuring strain on a downhole component includes: at least one strain sensitive device disposed proximate to a surface of a component of a drilling assembly or disposed within a material forming the component; and a processor in operable communication with the at least one strain sensitive device, the processor configured to detect changes in the at least one strain sensitive device and detect at least one of erosion, crack formation and crack propagation in the component surface. An apparatus for measuring strain on a downhole component includes: at least one strain gauge deposited on a surface of a drive shaft or disposed within a material forming the drive shaft; and a processor in operable communication with the at least one strain gauge, the processor configured to detect changes in the at least one strain gauge and detect conditions affecting operation of the drive shaft.
