摘要： A hydraulically powered tractor includes an elongated body, two gripper assemblies, at least one pair of aft and forward propulsion cylinders and pistons, and a valve system. The valve system comprises an inlet control valve, a two-position propulsion control valve, a two-position gripper control valve, two cycle valves, and two pressure reduction valves. The inlet control valve spool includes a hydraulically controlled deactivation cam that locks the valve in a closed position, rendering the tractor non-operational. The propulsion control valve is piloted on both ends by fluid pressure in the gripper assemblies. The propulsion control valve controls the distribution of operating fluid to and from the propulsion cylinders, such that one cylinder performs a power stroke while the other cylinder performs a reset stroke. Each end of the gripper control valve is piloted by a source of high-pressure fluid selectively admitted by one of the cycle valves. The gripper control valve controls the distribution of operating fluid to and from the gripper assemblies. The cycle valves are spring-biased and piloted by fluid pressure in the propulsion cylinders, so that the gripper control valve shifts only after the cylinders complete their strokes. The pressure reduction valves limit the pressure within the gripper assemblies. These valves are spring-biased and piloted by the pressure of fluid flowing into the gripper assemblies. Some or all of the valves include centering grooves on the landings of the spools, which reduce leakage and produce more efficient operation. The propulsion control and gripper control valves include spring-assisted detents to prevent inadvertent shifting.

摘要： Embodiments of the present invention generally provide a method, apparatus, and system for monitoring conditions in wellbore in real time prior to setting an inflatable element in the wellbore. The inflatable element is inflated with an inflation tool run on a cable with one or more electrically conductive wires (the cable is commonly referred to as a nullwirelinenull). One or more sensors, internal or external to the inflation tool, are monitored before setting the inflatable element to verify well conditions are compatible with the inflatable element. The sensors may be internal or external to the inflation tool.

摘要： A system for forming a patch in a well at a location along a tubular string which has lost sealing integrity includes a central patch body 60, an upper expander body 52 carrying an upper seal 50 or 56, and a lower expander body 98 carrying a lower seal 102, 104. The running tool includes an inner mandrel 14 axially moveable relative to the central patch body, and one or more pistons 20, 30, 20A axially moveable relative to the inner mandrel in response to fluid pressure within the running tool. Top expander 48 is axially moveable downward relative to the upper expander body in response to movement of the one or more pistons, and a bottom expander 120 is axially moveable upward relative to a lower expander body. After the upper expander body and a lower expander body have been moved radially outward into sealing engagement with a downhole tubular string, the running tool is retrieved to the surface.

摘要： The invention provides a running tool for a wellbore component. In one aspect, the tool includes a body having a longitudinal bore therethrough with connection means at an upper end for connection to a tubular run-in string and a selective attachment assembly for a wellbore component therebelow. A flow directing member is disposed in the bore and is movable between a first and second position. At a predetermined flow rate through the member, the member moves to the second position and directs fluid towards the selective attachment assembly, thereby causing the running tool to become disengaged from the wellbore component after the wellbore component has been actuated and fixed in the wellbore.

摘要： A device for anchoring a drill string in a borehole formed in an earth formation is provided. The device comprises an anchoring member connected to the drill string and being movable between a retracted position in which the anchoring member is retracted from the borehole wall and an extended position in which the anchoring member is extended against the borehole wall so as to anchor the drill string to the borehole wall, and an activating member operable to move the anchoring member from the extended position to the retracted position by the action of pressure of drilling fluid present in the borehole.

摘要： An anchor system for high expansion applications is described. It features a gripping member that holds together a pair of links. The movement of the links is regulated to assure the gripping member moves into proper contact with the casing. Meshing gears or a pin and slot can do this, for example. The gripping member is shaped such that it can still transmit load through the links even if the pin connections fail. The gripping member is preferably contoured to the shape of the casing inner wall to enhance grip.
