    摘要： A tool for gripping a tubular workpiece comprises: a land element for reacting compressive load against an end face of the workpiece; grip elements and grip element carrier means; a main body with means for converting axial motion of the tool relative to the workpiece into radial movement of the grip elements from a retracted position to an engaged position exerting radial load on the workpiece; and retractor means for retracting the grip elements from the workpiece the tool is displaced axially away from the workpiece. The grip element carrier means may comprise a cylindrical cage with the grip elements being radially slidable within circumferentially-spaced windows in the cage. The means for converting axial movement and load into radial movement and load may comprise a cone or ramp surface that bears against the grip elements such that radial loads from the grip surfaces are carried through the main body.

    摘要： A piston tractor system can include at least two piston assemblies which sealingly engage a wellbore, and a pump which transfers fluid between an annulus isolated between the piston assemblies, and another annulus. A method of operating a piston tractor system can include sealingly engaging at least two piston assemblies with a wellbore, grippingly engaging one piston assembly with the wellbore, and then pumping a fluid from an annulus formed between the piston assemblies, while the other piston assembly is secured to a tubular string, thereby biasing the tubular string to displace through the first piston assembly. A method of advancing a tubular string through a wellbore can include sealingly engaging piston assemblies with the wellbore, each of the piston assemblies including a gripping device which selectively grips the wellbore, and one piston assembly including another gripping device which selectively grips the tubular string.

    摘要： The invention relates to a handling unit for drill rods, having an elevator bracket (30), which can be pivoted by means of a tilt arm (34) under the influence of a tilt cylinder (32), and means (42) for the detecting a position of the at least one elevator bracket (30). The handling unit comprises at least one valve (50) as means for the position detection of the or each elevator bracket (30) and as part of a hydraulic switching control circuit (54) that continues outside the handling unit and at least one connecting member (52) for the at least one valve (50), which member can be moved by means of a movement of the tilt arm (34), wherein the or each valve (50) opens the hydraulic switching control circuit (54) when the connecting member (52) is in a first position and wherein the or each valve (50) closes the hydraulic switching control circuit (54) when the connecting member (52) is in a second position, such that the state of the switching control circuit (54) can be evaluated as position information.
