    摘要: A core sample from an oil or gas well can be quickly and easily inserted and removed relative to a reusable sealing sleeve fixed within a test housing wherein the core sample is tested for both longitudinal and lateral strain in response to applied stress. Young's modulus and Poisson's ratio can be determined from the strain and stress information. Pressures and temperature can be set to simulate downhole conditions inside the apparatus.

    摘要: The dynamic pressure tester includes a first cylinder and a first piston movable relative to the cylinder. The piston may have one or more weights applied thereto. The cylinder is vibrated by a shaker table and pressure pulses in the fluid are transmitted to a stationary housing and to a second piston in the housing. The opposite side of the piston contacts a corrosive or caustic fluid also in contact with the sensor face of an article being tested. The pressure pulses are transmitted by the second piston and corrosive fluid to the sensor face, enabling dynamic pressure testing in the corrosive fluid.
