Description
Technical field:
The utility model relates to a kind of oil pipe, particularly a kind of oil pipe with hydraulic control lines.
Background technology:
The flow string of the flow string of the high-pressure oil-gas well of oil gas field and all Oil/gas Wells of offshore oil and gas field is all provided with storm valve when certain depth by land, the hydraulic control lines of storm valve upwards extends to ground or christmas platform from down-hole along the outer wall of production of hydrocarbons tubing string, be connected with hydraulic control system, be used in case of emergency high-speed switch storm valve manually or automatically, ensure the safety of Oil/gas Well and christmas platform.The external diameter of the hydraulic control lines of storm valve is less (being generally less than 1/8 ＂), its installment state is such: hydraulic control lines one end is connected with storm valve, the other end is connected with the hydraulic control system on ground or christmas platform, mid portion is close to the outer wall of OIH gas flow string, with production of hydrocarbons tubing string parallel arranged, be fixed on OIH gas flow string at interval of 3 ~ 4 meters with dedicated pipeline clamp.This installment state plays lower tubular column operation bring following difficulty and risk to repairing completion: because the production of hydrocarbons tubing string in well and hydraulic control lines independently install side by side, middle also have pipeline clamp, cause and rising in lower tubular column operation process, the seal of the preventer of well head cannot with tubing string fitted seal in well, effectively cannot control well head by preventer when there is overflow or blowout in well.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of oil pipe with hydraulic control lines, the arrangement achieves and has ensured blowout preventer seal and tubular column main body effective sealing between lower tubular column operational period, has been conducive to the construction of lower tubular column job safety.The hydraulic control lines overcoming existing storm valve is arranged on outside oil pipe, cause wellhead blowout preventor seal cannot with the deficiency of tubing string effective sealing in well.
Technical solution adopted in the utility model is: a kind of oil pipe with hydraulic control lines, comprises oil pipe body; Oil pipe body one end is provided with oil pipe male joint, the oil pipe body other end is provided with oil pipe neck, oil pipe neck connected pipes box cupling, the external diameter of oil pipe body is greater than the external diameter of oil pipe neck and oil pipe male joint, be provided with embedded type hydraulic in the sidewall of oil pipe body and control pipeline, embedded type hydraulic controls pipeline two ends and is all connected with hydraulic control lines joint.
Hydraulic control lines joint adopts steel ferrule-type compression joint.
The beneficial effects of the utility model are: hydraulic control lines is embedded in the mode of oil pipe base side pars intramuralis by the utility model owing to have employed, oil pipe body outer wall is column type, thus ensure that blowout preventer seal and tubular column main body effective sealing between lower tubular column operational period, be conducive to the construction of lower tubular column job safety.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of oil pipe with hydraulic control lines, comprises oil pipe body 1; Oil pipe body 1 one end is provided with oil pipe male joint 2, oil pipe body 1 other end is provided with oil pipe neck 3, oil pipe neck 3 connected pipes box cupling 4, the external diameter of oil pipe body 1 is greater than the external diameter of oil pipe neck 3 and oil pipe male joint 2, be provided with embedded type hydraulic in the sidewall of oil pipe body 1 and control pipeline 5, embedded type hydraulic controls pipeline 5 two ends and is all connected with hydraulic control lines joint 6.Hydraulic control lines joint 6 adopts steel ferrule-type compression joint.Steel ferrule-type compression joint is made up of cutting ferrule, fittings body, nut.Cutting ferrule is with the metal ring with cutting edge inside the conical surface, leading portion outside a front and back end; Fittings body is equivalent to extrude grinding tool; The effect of nut promotes cutting ferrule, and outside the leading portion making cutting ferrule under the effect of fittings body inner conical surface, arch upward in middle part, the shrinkage strain of cutting ferrule front inner diameter, causes cutting ferrule leading inside cutting edge to block pipe.If continuation tightening nut, be fastened in deformation process and cutting edge will be forced to cut steel pipe formation sealing.And form conical surface seal with the inner conical surface of fittings body, nut respectively outside cutting ferrule front and back end.Steel ferrule-type compression joint is connected firmly, good airproof performance, withstand voltage height.Steel collar joint fitting operation is easy, uses extensively.
The profile of oil pipe body 1 is identical with conventional this body profile of oil pipe, in column type, surface smoothing, can with the seal fitted seal of the wellhead blowout preventor matched.Oil pipe neck 3 for using pipe elevator to suspend oil pipe in midair in lower tubular column operation process.Embedded type hydraulic controls pipeline 5 and is embedded in oil pipe body 1, and the external diameter of embedded type hydraulic control pipeline 5 is less than the wall thickness of oil pipe body 1.
During use, oil pipe male joint 2 of the present utility model is docked with the tubing coupling of another root oil pipe by lower tubular column method routinely, above buckle.Connection between hydraulic control lines joint 6 is according to the distance between adjacent two hydraulic control lines joints 6, intercept one section of supporting stainless steel high pressure line, two adjacent hydraulic control lines joints 6 are connected to stainless steel high pressure line two ends, after pressure testing is qualified, then enter under the oil pipe carrying out next root band hydraulic control lines and connection between hydraulic control lines joint.In the operation process playing lower tubular column, when tubing coupling 5 of the present utility model and oil pipe male joint 2 are by preventer, the mode that two groups of open flow devices can be adopted to switch ensures that tubing coupling 5 and oil pipe male joint 2 are passed through smoothly.
Lift pipe string method of the present utility model is as follows: with working rig, the oil pipe of band hydraulic control lines is proposed well head, first to dismantle hydraulic control lines joint and stainless steel hydraulic pressure high pressure line, lift pipe string method routinely dismantles oil pipe thread again, trips out the single oil tube of band hydraulic control lines.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
