    Abstract: A flow sub (100) for use with a drill string includes: a tubular housing (105) having a longitudinal bore formed therethrough and a flow port formed through a wall thereof; a bore valve (110) operable between an open position and a closed position, wherein the bore valve allows free passage through the bore in the open position and isolates an upper portion of the bore from a lower portion of the bore in the closed position; and a sleeve (121) disposed in the housing and movable between an open position where the flow port is exposed to the bore and a closed position where a wall of the sleeve is disposed between the flow port and the bore; and a bore valve actuator operably coupling the sleeve and the bore valve such that opening the sleeve closes the bore valve and closing the sleeve opens the bore valve.

    Abstract translation: 一种用于钻柱的流动副（100）包括：具有穿过其形成的纵向孔的管状壳体（105）和通过其壁形成的流动口; 孔可在打开位置和关闭位置之间操作，其中所述孔阀允许在所述打开位置自由地通过所述孔，并将所述孔的上部与所述孔的下部隔离在所述关闭位置; 以及套筒（121），其设置在所述壳体中并且可在所述流动端口暴露于所述孔的打开位置和所述套筒的壁之间设置在所述流动端口和所述孔之间的关闭位置之间移动; 以及可操作地联接套筒和孔阀的孔阀致动器，使得打开套筒关闭孔阀并关闭套筒打开孔阀。

    IPC: E21B37/00

    Abstract: A wellbore cleaning tool 10 for removing irregularities along the inner surface of a wellbore tubular is disclosed. The cleaning tool 10 includes a top sub 110, a cutting assembly 100, and a bottom sub 130. The tool 100 is operable to remove irregularities, such as debris, burrs, and jagged edges, along the inside of the wellbore tubular, and thereby provide a clean, inner surface finish. The tool 10 may be actuated into a retracted position, an extended position, and/or a deactivated position. A method of operating a wellbore tool 10 is also disclosed. Yet further a wellbore tool locking assembly is also disclosed. FIG 1 FOR PUBLICATION FIG'S 2 & 3 107z107 '147,-, FIG. 1 FIG. 2 FIG. 3
