Abstract:
Circulation Subassembly The present invention relates to acirculation subassembly (circsub) for incorporation in a drill pipe. The circsub has a flow through condition in which the circsub allows fluid to flow through a bore of the circsub and does not allow fluid communication between the bore of the circsub and an annulus located outside the drill pipe, a partial bypass condition in which the circsub allows fluid to flow through the bore of the circsub and allows fluid communication between the bore of the circsub and the annulus, and a full bypass condition in which the circsub does not allow fluid to flow through the bore of the circsub and allows fluid communication between the bore of the circsub and the annulus. An actuator is provided to change the circsub between conditions under the control of a controller.

Claim (Index 33):
A circulation subassembly (circsub) for incorporation in a drill pipe, the circsub comprising a piston movable within a bore of the circsub in a first direction by pressure of fluid within said bore, the piston having:\n a position corresponding to a flow through condition of the circsub in which the circsub allows fluid to flow through a bore of the circsub and does not allow fluid flow from the bore of the circsub through bypass orifices in the circsub into an annulus located outside the drill pipe; and a position corresponding to a full bypass condition of the circsub in which the circsub does not allow fluid to flow through the bore of the circsub and allows fluid communication through said bypass orifices from the bore of the circsub into the annulus, wherein the circsub further comprises biasing means for biasing the piston in a second direction opposite to the first direction, and a selectively adjustable abutment for limiting the movement of the piston in said first direction to each of said positions.
