摘要： A downhole component including a member having an outer surface, a constrained element configured to move relative to the member between a first position and a second position, and an on-demand hydrostatic/hydraulic trigger system including a constraining element operable to selectively release the constrained element. The on-demand hydrostatic/hydraulic trigger system includes a piston cylinder.

摘要： A method of forming a high temperature sensor includes preparing a substrate having a surface from an electrically insulative material having a first coefficient of thermal expansion (CTE), preparing an electrical conductor from a metal material having a second CTE that is different from the first CTE, and creating an interface between the electrical conductor and the substrate with a CTE blending medium that is provided between the substrate and the electrical conductor. The CTE blending medium accommodates differing thermal expansion rates of the substrate and the electrical conductor at temperatures of at least 700° C.

摘要： An electrical connector for use in downhole environment and methods for use are provided. In one aspect, an electrical connector comprises a substantially cylindrical connector body having a first end and a second end. A groove is formed around an outer surface of the connector body wherein the groove has a first substantially conically beveled surface on a side of the groove proximate the second end. A back-up ring has a second substantially conically beveled surface and is adapted to act cooperatively with an elastomer seal to close an extrusion gap between the connector body and a surrounding surface when the elastomer seal is exposed to a positive differential pressure from the first end to the second end. In another aspect, a conical surface on the connector body is forced to engage a mating surface on a bulkhead, thereby forming a metal to metal seal.

摘要： An electrically conductive ceramic composite conductor configured for downhole operations includes a first portion formed from an electrically non-conductive ceramic material having a first coefficient of thermal expansion (CTE). The first portion includes an outer surface. A second portion is disposed radially inwardly of the outer surface. The second portion is formed from an electrically conductive ceramic material having a second CTE that is substantially similar to the first CTE.
