摘要： A debris catching device for downhole milling features modular debris receptacles that are held in the housing in a manner that facilitates stacking and a generally undulating flow path to facilitate dropping of the debris into the receptacles as the remaining fluid travels up the tool for ultimate screening before the fluid exits the tool to flow up to the surface or in a reverse circulation pattern back to the mill below the debris catcher. The modules can also be aligned with flapper valves at the top of each module to prevent debris in the tool from falling to the mill if circulation is turned off. The mill is configured to have an off-center return path preferably as large as the passage through the mill body to aid circulation and cutting performance.

摘要： A milling bottom hole assembly (BHA) for use in cutting a full gauge window in a wellbore casing wall, the resultant length of the window being greater than or equal to the whipstock ramp length. A milling BHA is described which includes two shaft portions, a window mill and two bearing mills. The design, which involves strategically placed bearing mills, allows the milling BHA to stay on the whipstock ramp for the entire casing window milling operation and, thereafter, to optimally rapidly build angle and move laterally away from the whipstock and casing, creating a significantly long window which allows for easy passage of directional drilling BHAs through the milled window.

摘要： A mill body is machined integrally with blades that have pockets to receive PDC inserts. The insert pockets can have an orientation feature to ensure that inserts that require specific rotational orientation are put into the pockets at the right orientation for efficient milling. The orientation of some of the pockets closest to the bottom and center of the bit have their axis reoriented to a near parallel orientation to the bit center axis to allow the bit body and blade fabrication equipment access to drill the insert pocket.

摘要： A method and apparatus for cutting one or more longitudinal members, external to a downhole tubular conduit, by pulling upward on a cutter body attached to the tubular conduit, where the longitudinal members are run between cutter knives within the cutter body. The cutter knives are attached to one external longitudinal member. After the main tubular conduit is cut below the cutter body, the tubular conduit is pulled, lifting the cutter body, thereby engaging the cutter knives with sloping surfaces on the cutter body to force the knives together, severing the external longitudinal members.
摘要翻译：通过在附接到管状导管的切割器主体上向上拉动，在纵向构件在切割器主体内的切割刀之间延伸的方法和装置，用于在井下管状导管的外部切割一个或多个纵向构件。切割刀连接到一个外部纵向构件。在主管状导管在切割器本体的下方切割之后，拉动管状导管，提升切割器本体，从而使切割刀与切割器主体上的倾斜表面接合，以将刀强制在一起，从而切断外部纵向部件。
