    摘要: The present invention relates to a rock strength evaluation device including a frame, a cutter support mounted on the frame, the cutter support being rotatable relatively to the frame about a rotation axis; a cutter mounted on the cutter support, and a rock sample support mounted on the frame. At least one of the cutter support and rock sample support is movable relative to one another in a sliding direction and the rotation axis is perpendicular to the sliding direction

    摘要: The invention relates to a metrology device for determining the quality of a hygroscopic material. The metrology device includes a frame, a support element, two tips that can move in translation with respect to the frame, means for measuring a penetration effort of each tip as a function of a force applied to each tip, means for measuring an electrical resistivity between the ends of the two tips, which means are able to measure an electrical resistivity of the hygroscopic material when the two tips are inserted into the hygroscopic material, and means for measuring a penetration effort of the support element as a function of a force applied to the support element in order to achieve a predetermined fixing position. The support element is adapted to penetrate into the hygroscopic material so as to fix the frame to the hygroscopic material.

    摘要: The method for determining fracture toughness includes clamping a cutting element in a first orientation, exerting a confining pressure on the cutting element, applying a first load at a first distance from a perimeter of the diamond table of the cutting element, increasing the first load to a first level sufficient to fracture, and recording the first level sufficient to fracture. Then, another load is applied at another distance from a perimeter of the diamond table with another cutting element or the same cutting element in another orientation. The load is increased until fracture again. The steps are repeated at different distances and different orientations to create a profile of the fracture toughness of the cutting element. The method also includes wearing the cutting element and measuring fracture toughness at a worn distance. The profile is a more complete rating of the cutting element under drilling conditions.

    摘要: A method and system for improving cuttings measurements in drilling operations includes rotating a helical screw in a trough at a first speed, measuring a first weight of a cuttings mixture within the trough, measuring a first torque required to maintain rotation of the helical screw at the first speed through the cuttings mixture, and calculating a difference between the first torque and a second torque required to maintain rotation of the helical screw at the first speed through a second weight of natural cuttings equal to the first weight.
