摘要： The invention provides an apparatus for actuating a downhole tool by utilizing a pressure differential created by fluid flowing through a conduit. The conduit is in communication with a pressure sensing line that is selectively exposable to areas of the conduit having different pressures. By exposing the pressure sensing line to a portion of the conduit having a predetermined pressure therein, the pressure sensing line causes actuation of a hydraulic tool therebelow.

摘要： The present invention, in one aspect, discloses a system for selectively anchoring a wellbore tool at a desired location in a wellbore or tubular member such as casing or tubing; such a system with a selectively settable anchor assembly that has a piston that is moved upwardly by fluid under pressure from the surface thereby moving one or more movable slips out from a body of the anchor assembly to set the anchor assembly in place; and such a system with a whipstock connected to the anchor assembly. Fluid under pressure pumped from the surface down a workstring to which the system is connected flows to the anchor assembly through or adjacent the whipstock. In one aspect a mill (or mills) is releasably connected to the whipstock. In one aspect, fluid under pressure flows through or adjacent the mill(s) to the whipstock. In one aspect a selectively actuable valve assembly is provided for selectively controlling the flow of fluid under pressure from an inlet end of the valve assembly out through an outlet end thereof for flow, e.g., to a mill, whipstock and/or anchor assembly. In one aspect such a valve assembly is used with a system as previously described to selectively provide actuating fluid under pressure to an anchor assembly as described to set the movable slip(s) thereof and, in one aspect, to then provide jetting fluid to jetting ports of the mill(s) upon release of the mill(s) from a whipstock.

摘要： The present invention, in one embodiment, discloses a whipstock system having an orientation device; a flexion member releasably secured to the orientation device; co-acting lower and upper body members, the lower body member interconnected with the flexion member; a connecting bar which connects the upper and lower body members permitting the upper body member to move downwardly with respect to the lower body member while preventing separation of the two body members; and a concave member secured to and above the upper body member. In one preferred embodiment, one or more movable pawls on the connecting bar move to engage surfaces on one or both body members to prevent upward movement of the upper body member with respect to the lower body member, or conversely movement of the lower body member downwardly away from the upper body member; and movement of the one or more pawls in contact with both body members also forces the two body members apart further stabilizing the system in a tubular. Also disclosed is a setting or installation tool with a mandrel rotatable in an upper housing, the mandrel secured to a lower housing, so that torque or torsion is not transmitted through the tool. Also disclosed is a toggling connection member which permits a concave member to be pushed and then to move upwardly to pivot to a desired position.

摘要： The present invention discloses a whipstock assembly (100) for use in forming a lateral borehole from a parent wellbore. The whipstock assembly comprises a body (122) and a deflection member 120) above the body. The deflection member includes a concave portion (111) for deflecting a milling bit during a milling operation. Disposed on a perforation plate (110) portion of the concave portion is a raised surface feature (116). The raised surface supports a milling bit above the perforation plate portion during a milling operation. This, in turn, substantially prevents frictional contact between the milling bits and the perforation plate portion during a milling operation. The present invention also provides a novel method for manufacturing a whipstock in which a cavity portion is formed behind the perforation plate by milling out the backside of the deflection member and then joining a second back cover member to the whipstock body to complete the assembly.
