    摘要： An extended life seal is incorporated into a drill bit used for drilling a wellbore. The drill bit can include a seal surface, a seal which engages the seal surface, and a groove which compresses the seal greater on opposite axial sides than at a central portion of the seal. The drill bit may include the seal having a cylindrical surface which engages the seal surface, and another cylindrical surface opposite the first surface, and the groove having a third cylindrical surface which engages the second surface, and wherein the groove simultaneously biases the seal toward the seal surface on opposite axial sides of the third surface. The drill bit may include the seal having right cylindrical shaped inner and outer surfaces, and a contact pressure between the seal surface and the seal being greater at each opposite side of the seal than at a central portion of the seal.

    摘要： Systems and methods are provided for swellable material activation and monitoring in a subterranean well. A sensor system for use in a subterranean well includes a swellable material, and at least one sensor which is displaced to a wellbore surface in response to swelling of the swellable material. Another sensor system includes a sensor which detects swelling of a swellable material. A swellable well tool system includes a base pipe, a swellable material on an exterior of the base pipe, and eccentric weighting for inducing rotation of the swellable material about a longitudinal axis of the base pipe.

    摘要： The present disclosure provides mechanical attachments of TSD body to a carrier or substrate sufficient to allow eventual conventional attachment of the TSD to a drill bit or other component. According to one aspect, the disclosure includes a composite assembly including a thermally stable diamond (TSD) body and a substrate with aligned holes and a joining pin located in the aligned holes to mechanically attach the TSD body and substrate. The composite assembly may lack any non-mechanical attachment between the TSD body and the substrate, or may lack particular types of non-mechanical attachments. The disclosure also provides drill bits and other devices containing such composite assemblies as well as methods of making such composite assemblies and drill bits or other devices.
