摘要： Methods for forming a polycrystalline diamond compact (PDC) drill bit from catalyst-free synthesized polycrystalline diamonds are described. The polycrystalline diamonds are deposited within a mold. In some cases, a matrix body material is deposited within the mold, and an infiltration process is performed to bond the polycrystalline diamonds to the matrix body material to form the PDC drill bit. In some cases, a drill bit body is formed within the mold, and forming the drill bit body within the mold includes depositing a layer of matrix body material particles within the mold, depositing an adhesive ink within the mold, and curing the adhesive ink. In some cases, a sintering process is performed after forming the drill bit body to remove at least a portion of the adhesive ink and increase a density of the drill bit body to form the PDC drill bit.

摘要： A self-powered sensor array (SPSA) for sensing environmental parameters along a drillstring includes an outer collar having moveable member retainers with moveable members movably located in the moveable member retainers. An inner ring is rotatably supported within the outer collar with bearing elements on an outer surface of the inner ring positioned to displace the moveable members relative to the moveable member retainers in response to relative rotation between the inner ring and the outer collar. Shape memory material elements are arranged in a respective moveable member retainer. Distance sensors are configured to sense a gap responsive to a shape change of the respective shape memory material element and a displacement of the respective moveable member. Power generation components are configured such that, in response to the relative rotation, the bearing elements displace a particular moveable member into a particular moveable member retainer, generating an electric charge.
