摘要： A single-trip whipstock unit including three parts: milling apparatus (1), whipface (2) and anchor apparatus (3). These parts are connected together, from top to bottom, respectively. The anchor (3) prevents the downward motion and rotation of the whipface (2). The milling apparatus (1) is connected to the top of whipface (2) by a shearable attachment (9) which is then detached by applying shear force. The whipface (2) has a tapered deflection surface.

摘要： A multi-string section milling tool has a longitudinally extending tubular body with mill carriers carrying hardened cutters that pivotally extend from a mill window in the tubular body by upward movement of a drive plunger, A downwardly biased piston mounted to the upper end of a flow tube is slidably inserted through a stationary thimble below the piston. The lower end of the flow tube is attached to a drive plunger which is pivotally attached to drive yoke links pivotally attached the mill carriers. The piston and thimble creates a pressure chamber in the milling tool. Fluid pressure in the pressure chamber moves the piston, flow tube and drive plunger upward to pivotally extend the drive yoke links and mill carriers radially outward through the mill window. Cessation of fluid pressure in the pressure chamber retracts the mill carriers.

摘要： A method of forming a casing window in a casing tubular includes introducing a bottom hole assembly (BHA) into a casing tubular, running the bottom hole assembly to a selected position in the casing tubular, directing an ultrasonic wave from the BHA toward the casing tubular, receiving a reflection of the ultrasonic wave at the BHA, and evaluating the reflection of the ultrasonic wave to determine one or more parameters associated with the casing tubular and supporting structure.

摘要： A downhole tool includes a housing configured to be connected between two tubular members. The housing includes a chamber and a plug assembly is disposed in the chamber and divides the chamber into an up-hole portion and a downhole portion. The plug assembly includes a glass member having a predetermined residual surface compression, at least a first face, and at least one strength-reducing surface feature on the first face. The strength-reducing surface feature is configured to cause the glass member to disintegrate when the glass member is exposed to a pressure in the up-hole portion of a magnitude that creates a tensile stress on the first face that exceeds the predetermined residual surface compression.
