摘要： A method of producing a side pocket mandrel body for use in a hydrocarbon well side pocket mandrel assembly includes providing a continuous, solid piece of material with the through-going main conduit; in the solid piece of material, forming said at least one side pocket by machining a bore, displaying an external entrance opening, into a laterally offset section of the solid piece of material generally parallel to the main conduit such that an internal wall section of the solid piece of material is brought to separate the main conduit from the machined bore; plugging the entrance opening of the machined bore with a fluid-tight plug; providing at least one opening from an outside of the mandrel body into the at least one side pocket; providing at least one opening in the wall section; and providing the solid piece of material with the first and the second connection arrangements, thereby rendering the mandrel body connectable to the up-hole and down-hole sections of the production tubing.

摘要： A wellhead port plug assembly includes a first plug body including connection elements allowing the first plug body to be sealingly and removably mounted in a port of a wellhead of a hydrocarbon well. The plug assembly includes a spool unit displaying an axial through-channel extending between a first end and a second end of the spool unit, which spool unit includes a first flange section arranged at the first end for sealingly mounting the spool unit to the wellhead aligning the through-channel with the port, and a second flange section arranged at the second end; a second plug body including connection elements allowing the second plug body to be sealingly and removably mounted in the through-channel; and a blind flange which is sealingly and removably mounted to the second flange section allowing the second plug body and the first plug body to be removed from the wellhead via the through-channel.

摘要： The present invention relates to a valve system for use in a wellbore, the system comprising a side pocket mandrel and one or more well tools, where the side pocket mandrel (6) comprises an elongated body section (7) provided with connection means (8) at its ends, the elongated body section (7) being provided with a substantially fully open main bore (9) for alignment with the well tubing (3) and an offset side pocket bore (10). At least one through opening (12) is provided in the side pocket mandrel (6), leading into the side pocket bore (10), and at least one through opening (13) is provided in the internal wall (11), leading into the main bore (9), where the at least two openings (12, 13) are in fluid communication through the side pocket bore (10), in which side pocket bore (10) at least two valves (100, 101) are arranged in series to form a double fluid barrier between the main bore (9) and an outside of the pocket mandrel (6), the at least two valves (100, 101) being independently retrievable through at least one installation opening arranged in the internal wall (11) of the side pocket mandrel (6).

摘要： The present invention regards a device designed for injection of fluids in a well bore, typically an offshore well bore for petroleum production and gas injection / gas lift system for fluid injection. The device comprises a outer hollow housing (1) with an internal body (3) moveable within the outer housing (1) which in a first closed position is closed with a metal to metal seal system between the outer housing (1) and the internal body (3), which internal body (3) is operated by pressure differential across the internal body (3). The internal movable body (3) is connected to the outer hollow housing (1) by means of a retainer key (6). The retainer key (6) comprises a shear arrangement and is arranged to keep the valve in a fixed closed position, where fluid pressure is to overcome the pretension of the retainer key (6) in order to open the device. When the device is shear opened, it can be kept in this open position as the retainer key (6) is locked to the outer hollow housing (1).

摘要： The present invention regards a surface controlled device designed for injection of fluids in a well bore, typically an offshore well bore for petroleum production and gas injection / gas lift system for fluid injection. The device comprises a outer hollow housing (1) with at least one inlet and outlet and an internal body (2) moveable in a longitudinal direction within the outer housing (1). An inlet, in form of a variable orifice, is connected, through a mainly longitudinal bore of the internal body, with at least one slot. The present invention will give a fluid exiting the device with a minimal amount of energy or pressure loss over the device.

摘要： The present invention relates to a valve device comprising an external structure with a longitudinal axis and a valve seat, and a valve body mounted movably inside the external structure. The valve device comprises a first bellows device permitted to be moved in a substantially radial direction, in fluid connection with a first fluid, and hydraulically connected to a second bellows device permitted to be moved in a substantially axial direction. The second bellows device is connected to a first part piston cooperating with a second part piston, thereby giving the second part piston an oppositely directed movement relative to the first part piston, which thereby moves the valve body relative to the valve seat. The invention also relates to a method for operation of a valve device and the use thereof.
