    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 debris catcher uses induced circulation from a venturi to urge debris laden flow into the lower end of a housing. An inlet tube maintains velocity so as to keep the debris moving with the fluid stream as it goes up the inlet tube. A screen fits over the open end of the inlet tube and runs down around the inlet tube toward the entrance of the debris laden fluid into the lower end of the housing. There is a clearance around the cylindrical portion of the screen so some flow can exit that way. There is also an open exit through the top of the screen that can be reached after the fluid stream makes two hairpin turns. Many modules can be stacked. Each module has a large screen area for flow to exit and progressive modules can have smaller screen openings in an uphole flow direction.

    摘要： A gearbox comprises a plurality of gear pairs each having a specific gear ratio, and a plurality of selectors each mounted between two gear pairs for selecting one of the two gear pairs, wherein the gear ratio of the selected gear pair is cascaded through an output shaft to another two gear pairs having another selector, and so on. In this way, the effective or aggregate gear ratio of the gearbox is the product of the gear ratios of the selected gear pairs. Thus, the number of available output speeds excluding neutral is given by 2n, where n=(number of gear pairs)/2.
