摘要： The present invention is directed to an apparatus and method for coring a borehole in a hard rock sidewall of a well bore in a subterranean formation for testing purposes. The apparatus includes a drive motor for operation down hole, a flexible drive shaft coupled to the drive motor and a coring bit coupled to the flexible drive shaft, such that the coring bit is directly driven by the drive motor. The apparatus also includes a control circuit for controlling advancement of the coring bit into the subterranean formation. The apparatus also includes a rotating carousel for storing multiple core samples. The method includes the steps of activating the drive motor to rotate the output shaft; coupling the output shaft of the drive motor to the flexible drive shaft and rotating the coring bit with the flexible drive shaft.

摘要： An assembly is provided that can include check valve. The check valve can include a ball positioned between an inflow line and an outflow line. The ball can be movable between (i) an open position at which a fluid is allowed to flow between the inflow line and the outflow line and (ii) a closed position at which the fluid is prevented from flowing between the inflow line and the outflow line. The assembly can also include a spring positioned adjacent to the ball and operable to bias the ball in a closed position. The assembly can further include a poppet positioned adjacent to the ball. The poppet can be movable in response to a communication of a pilot pressure to the poppet. Further, the ball can be movable to the closed position in response to a force applied by the poppet.

摘要： A sampling tool to sample core samples from a wellbore is disclosed. A core sampling storage module includes a pressure housing to store a plurality of core samples, a core tube within the pressure housing, the core tube to store a plurality of core samples drilled from a downhole formation, a pressure housing cover that is configured to be selectively rotated to an open position or a closed position, an activation mechanism to receive a command, and based on the command, open or close the pressure housing cover, a push rod to selectively install a plug to cover the core tube, wherein when the plug is installed the pressure housing maintains a pressure.
