Definitions
- the present invention relates to a production tube with integrated hydraulic line.
- safety standards stipulate that the well head must be equipped with a subsurface safety valve placed in the well at a depth of about 30 m below the surface (salt or seabed) . This valve is intended to close the well in the event of an incident, it is in most installations hydraulically actuated.
- the safety valve disposed deep is designed to have a closed rest position, the valve being held in an open position under the effect of the hydraulic pressure sent from the surface. In the event of an incident, the hydraulic pressure is purged, which causes the valve to close. Thus, if the wellhead is destroyed, the safety valve closes automatically.
- the hydraulic passage is constituted, in a conventional manner, by a small diameter hydraulic conduit - for example 6 mm - which is arranged outside the production tubes between the valve and the well head arranged either on the surface or at the bottom the water.
- the hydraulic line must be put in place on the tubes before installing them in the well. This procedure has many drawbacks.
- the hydraulic conduit arranged between the tubes and the casing, is located in a medium may be or become corrosive, consisting for example of brine, reducing sulphate bacteria, traces of corrosive gas and. , medium which can deteriorate in the more or less long term the hydraulic conduit.
- the present invention therefore aims at a production tube with an integrated hydraulic line which is adapted to overcome these drawbacks, and which is of simple construction and of increased reliability.
- the invention provides a production tube comprising at least one tube element of substantially tubular shape and a hydraulic line characterized in that the tube element is provided with a longitudinal groove in which is disposed the hydraulic line .
- FIG. 1 is a schematic view of an offshore well provided with a known type of completion
- - Figure 2 is a longitudinal sectional view of a well tube according to the invention; and - Figure 3 is a partial section taken along line III-III of Figure 2.
- FIG. 1 is shown, schematically, an eruptive production well of known type formed by a production reservoir 10 and in which is disposed a column of production tues, represented at 12.
- a well head made up of valves 14 and 16 is conventionally mounted on the upper part of the column 12.
- An anti-blowout device or safety valve 18 is mounted on the column 12 at least 30 meters below ground level or from the bottom of the sea 20.
- This safety valve 18, mounted at the end of the casing 12, is intended to be controlled by a hydraulic line 24 which extends along a few tubes 12 and outside thereof.
- the tube shown in Figure 2 has a line. integrated hydraulic.
- the tube 12 is formed of two elements shown partially at 26 and 28 which are connected together by a thread 30.
- An axial passage 32, formed inside the tube 12, is generally sealed by this thread which has a metal / metal bearing 34.
- the element 26 of the tube 12 is formed with a longitudinal groove 38 in its outer surface 40, a groove which has a substantially U-shaped section - see FIG. 3.
- the hydraulic line 24 formed of a metal tube having an external diameter of approximately 6 mm is disposed along the groove 38. As shown in FIG.
- the groove 38 is filled with solder 42 which serves to retain the hydraulic line 24 in place and to restore a continuous external surface to the element 26.
- the thickness -D- of the element 26 or 28 which is delimited by the bottom of the groove 37 or 38 corresponds to the thickness of a production tube of the classic type. So that the axial passage 32 keeps a constant cross section, the element 26 of the tube 12 has a part 44 of enlarged diameter.
- the groove 38 and the hydraulic line 24 follow the surface of the element 26 until the end 46 of the line 24 enters a longitudinal passage 48 drilled in the wall 50 of the element 26.
- the passage 48 is closed at its end 52 remote from the hydraulic line 24 by a threaded plug 54.
- the end 46 of the line is in hydraulic communication with a hollow chamber 56 formed between the two elements 26 and 28 via a passage 58 formed in element 26.
- the element 28 of the tube 12 is provided with a longitudinal groove 60 which is substantially similar to that 38 of the element 26 and comprises a hydraulic line 62 mounted as indicated below for the hydraulic line 24.
- Two recesses 55 and 57 are made respectively in the elements 26 and 28 to ensure perfect circular welding around the conduit 24 and 62 and to avoid any longitudinal migration under the welding of the grooves 40 and 60.
- a set of "chevron" seals "36 isolates the hydraulic oil from the liquid present in the annular space between the production column and the casing.
- An O-ring 35 doubles the tightness of the thread 30 and prevents any presence of screw-in grease in the hydraulic conduit.
