摘要： A substantially constant force actuator that is applicable to centralizers, anchors and tractors for use in wells and is applicable to lifting devices such as jacks and load supporting devices. One or more sets of linkage arms are angularly movable by the force of one or more force transmitting members from a minimum angle with the force transmitting members at maximum spacing to a maximum angle with the force transmitting members at minimum spacing to impart a substantially constant force to an object or surface, with the direction of the force being substantially perpendicular to the direction of relative linear movement of the force transmitting members. With the linkage arms at their minimum angles, movement control elements on at least one of the force transmitting members react with guide surfaces of the linkage arms to achieve angular linkage movement and to develop a substantially constant force during angular linkage movement.

摘要： A radially expandable tool is provided that includes a tool body and a radially moveable member coupled to the tool body and in force receiving relation to a constant force actuator. The radially moveable member is movable by the constant force actuator from an closed position to a plurality of radially expanded open positions, which includes a fully open position. The constant force actuator includes an opening arm having a force transmission member; and a movement control guide in force reacting engagement with the force transmission member. The tool also includes a linear force generator; which applies a linear force to the constant force actuator, which the actuator transfers to a radial force perpendicular to the linear force. When the linear force is constant, the radial force transferred by the actuator is constant for each radial position of the radially moveable member from the closed position to the fully opened position due to the interaction of the force transmission member and the movement control guide.

摘要： A conveyance apparatus for conveying at least one logging tool through an earth formation traversed by a horizontal or highly deviated borehole. The conveyance apparatus comprises a pair of arcuate-shaped cams pivotally mounted to a support member, a spring member for biasing the arcuate surface of each cam into contact with the borehole wall, and actuators operatively connected to each cam. A logging tool is attached to the conveyance apparatus. When either actuator is activated in a first direction, the cam connected to the activated actuator is linearly displaced forward and the arcuate surface of the cam slides along the borehole wall. When either actuator is activated in a second direction, the activated actuator pulls the connected cam backwards and the spring member thereby urges the arcuate surface of the cam to lock against the borehole wall. Once the cam is locked, further movement of the actuator propels both the conveyance apparatus and the logging tool forward along the highly deviated or horizontal borehole.

摘要： A downhole tractor is provided that may be used in open or cased wells, and is also designed for use in open holes having a variety of soil/formation consistencies (e.g., soft, firm, rigid, etc.), varying diameters and non-uniform and irregular bore profiles. The tractor may include a track assembly including a plurality of idler wheels and a continuous track rotatably disposed around the idler wheels. A motor may be adapted to rotate the track around the idler wheels. Upper and lower arms may be pivotally connected to opposite ends of the track assembly and pivotally connected to a tractor housing. An actuator arm or link assembly may be provided to impart an outward force to the track assembly to move the track assembly outwardly into an open position and a retracting force to retract the track assembly into a closed position. A rotatable screw may be connected to a second motor, or a rod may be connected to a hydraulic system, to actuate the actuator arm or link assembly.
