摘要： A hydraulic cutting tool, a system, and a method are for hydraulic cutting through a pipe wall of a pipe body. For this purpose, the cutting tool is provided with at least one cutting section comprising at least one fluid discharge body. Each such fluid discharge body comprises at least two outwardly directed discharge openings having non-parallel discharge directions directed at a common intersection point located outside the fluid discharge body. The cutting is carried out by means of an abrasive fluid being supplied, via a flow-through pipe string, to the at least one fluid discharge body from a remote location. Thereby, abrasive cutting jets will discharge at high velocity from the fluid discharge body so as to meet and disperse in the intersection point, thus weakening the further cutting ability of the cutting jets.

摘要： A method is for removing casing from a well. The method includes setting a first sealing element into fluid-sealing engagement with the inside of the casing, lowering a flow-through string into the well, a cutting tool and a second, reversibly expandable sealing element being connected to the string, forming perforations into the casing by means of said cutting tool, expanding the second, expandable sealing element into fluid-sealing engagement with the inside of the casing, passing a pressurized fluid through the string and into the annulus via the perforations, so that the viscous and/or solid mass is displaced up the annulus, cutting the casing around its entire circumference; and pulling a length of the casing up from the well.

摘要： A method is for cutting of at least one line disposed along a pipe string in a well. The method includes (A), using a cutting tool for selective cutting activation and provided with at least one cut-forming means for cutting in a radial direction outward from the cutting tool; and (B) lowering the cutting tool to a longitudinal section where the cutting is to be carried out. In (A), a cutting tool is used for controlled cutting in a peripheral direction and distributed in an axial direction relative to the cutting tool. The method further includes (C), activating the cutting tool and cutting, in the radial direction through and past the wall of the pipe string, at least one peripherally extending hole collectively covering the entire circumference of the pipe string, and also distributing the hole in the axial direction.

摘要： An improved autonomous well valve has a body that constitutes an actuator for opening and closing of first and second valves. The body has a body axis of symmetry. The body, which in operation is submerged, has an effective density that is equal or greater than the density of a first fluid and less than the density of a second fluid. The body is placed in a housing, the housing having a housing axis of symmetry. At least two first valves are designed to allow flow between the inside and outside of the housing, are distributed about the body axis and mechanically connected between the body and the housing. The body axis at the first valves is restricted from moving above the housing axis.
