摘要： A drill string and powered device system, comprising a drill string which comprises a plurality of drill pipe sections. It includes several conductive drill pipe sections, each conductive drill pipe section having a first end and a second end, and including a conductor. The conductor is connected to a first contact means at the first end and a corresponding second contact means at the second end. The drill string also has a powered tool having a first end and a second end corresponding to the first and second end of the drill pipe sections, including a contact means at the first end. The drill string is made up so that conductive drill pipe sections are connected in series above the powered tool such that there is a conductive path through the conductive drill pipe sections to provide power to the powered tool.

摘要： A sub surface deployment valve which is particularly suitable for use in underbalanced drilling operations which can be installed through an existing tubular string comprises a radially expandable body (1) having an internal bore and a valve element (2) capable of closing off the internal bore. The deployment valve can be installed by passing the valve through the existing tubular and then radially expanding the radially expandable body of the deployment valve to form a connection resulting from the interference between the external surface of the deployment valve and the tubular string.

摘要： An oil flow line and power device system has a tube for the transportation of oil and a power device which can be received in the tube. The tube is provided with an electric power transmission line extending along at least some of the length and has a first power transfer unit which can cooperate with a second power transfer unit on the power outlet device such that the other power transfer units cooperate to transfer power from the transmission line to the power device.

摘要： When drilling or completing an oil or gas well, it is often desirable to drill a borehole at an angle to the initial borehole. A process for deflecting a well tool towards the wall of a well bore comprises positioning within the well bore a radially expandable pipe designed to curve longitudinally when its diameter is expanded, expanding the diameter of the radially expandable pipe thereby causing the pipe to curve and passing the well tool through the curved pipe: The process is particularly suitable for through-tubing operations in which a lateral bore is initiated from a production well having within the well a smaller diameter production tubing ( 14 ) comprising (i) passing through the production tube ( 14 ) a radially expandable pipe ( 1 ) designed to curve longitudinally as its diameter is expanded, into a section of well bore ( 12 ) having a diameter greater than the diameter of the production tubing ( 14 ) (ii) expanding the diameter of the radially expandable pipe ( 1 ) thereby causing the pipe to curve, (iii) passing through the curved pipe a milling device or drill bit and (iv) milling the casing or drilling into the well bore wall.

摘要： A method for connecting tubular elements (37, 40), particularly pipe for strings to be used in oil and gas wells, comprises: (A) locating a portion o f a first tubular element (37) within a portion of a second tubular element (40), (B) expanding the portion of the first tubular element and/or compressing the portion of the second tubular element to form a connection resulting from the interference between the external surface of the portion of the first tubular element and the internal surface of the portion of the second tubular element, in which, prior to assembly, one or both of the external surface of the portion of the first tubular element and. the intern al surface of the portion of the second tubular element is/are at least partial ly coated by plasma spraying with hard angular material. Preferably, protuberances (38) of plasma-sprayed hard angular material are formed on at least one of the mating surfaces of the connection.
