Abstract
The utility model relates to a surficial movable steam injection tube used for conveying steam for a steam injection well when thick oil is mined by steam injection. The movable steam injection tube is composed of a steam injection tube and a spherical joint. Steam injection pipelines and consumption of steel product can be decreased with the movable steam injection tube. The utility model has the advantages of low cost, light weight, convenient construction, safety, etc. The movable steam injection tube can be prefabricated by factories.
Description
The utility model is used for when relating to a kind of exploitation via steam injection viscous crude annotating steam pipe to the land operations of annotating vapour well delivering vapor.
Steam soak is a kind of main method of heavy crude producing, at home and abroad is applied more and more widely in recent years.When implementing this technology, need lay the steam injection pipeline of carrying high temperature and high pressure steam to annotating the vapour well from steam generator, this kind steam injection pipeline is by main line and form to the branch line of individual well notes vapour respectively.At present, no matter annotating the vapour main line still annotates the vapour branch line and all adopts the fixed pipelines that is made of welded connection.The vapour well notes vapour time is shorter because single port is annotated, and gap periods is longer, thereby the utilization rate of notes vapour branch line is lower.Annotating that vapour well number is many, under the situation of employing fixed pipelines, need lay a large amount of notes vapour branch lines.Like this, not only increase the construction working amount and expend steel material, cost is improved, and cause serious waste.
Task of the present utility model provides a kind of movable steam pipe of annotating, and utilizes it can significantly reduce the length of laying the line, and reaches the purpose that reduces construction investment and annotate the vapour cost for oil production.
The utility model is achieved in that the movable steam pipe of annotating of this kind comprises notes steam pipe and globe joint two large divisions.Wherein, annotating steam pipe is made up of end plate 5, shell 6, fine groove glass wool cloth 7, super glass wool skin 8, super glass wool internal layer 9, iron wire 10, interior pipe 11, end pipe 12a, 12b, FlexbleJoint 13; Globe joint is made up of protecting cover 1, bulb 2, pressure ring 3, gland 4 and fittings body 14, baffle ring 15a, 15b, sealing ring 16a, 16b, protecting cover 17.The whole movable steam pipe of annotating can be in the following order by prefabrication: in earlier FlexbleJoint 13 being welded on the pipe 11; 9 claddings of super glass wool internal layer on interior pipe 11, are tightened with iron wire 10; Clad super glass wool skin 8 again, tightly wrap with fine groove glass wool cloth 7; Suit end pipe 12b, high-density polyethylene plastics pipe shell 6 and end are managed 12a successively; Welded end plate 5 again; At last, interior pipe 11 two ends are welded as a whole with the globe joint two ends respectively; The joint two ends put protecting cover 1,17 respectively and can dispatch from the factory for on-the-spot use.The number of assembling steps of globe joint is: in the fittings body 14 of earlier baffle ring 15b and sealing ring 16b being packed into; Pack into behind the bulb 2, load onto sealing ring 16a, baffle ring 15a and pressure ring 3 more successively; At last, the eyelet rotation of inserting on the pressure cap 4 with special-purpose wrench tightens pressure cap 4 and fittings body 14 by screw thread.
This activity annotate steam pipe can be made into full-length (6.5~7.5m), when individual well need be annotated vapour, after some annotated steam pipes and put by broken line, be connected to by globe joint again and annotate the vapour well head, can annotate vapour.After annotating vapour and finishing, its dismounting come just can be used further to other wells and annotate vapour.The movable spherical active joint of annotating steam pipe of this kind adopts the sphere combination, can be movable in 30 ° of garden cone angle scopes, rotation displacement is flexible, thereby except that being used as on the whole the steam injection pipeline, the deviation that occurs on the angle in the time of also can separately active joint being used to adjust thermal production well mouth, piping erection can adapt to the random inverter tube line position of different angles; Be used for pipeline is connected with chamber fixture apparatus such as well head, basins.In addition, this active joint also can be to the dilatation redeeming of pipeline under the thermal stress effect.
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 annotates the structural representation of steam pipe globe joint for this.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
It is the garden shape A3 steel plate of 3mm that the utility model is annotated steam pipe part end plate 5 employing thickness, and shell 6 adopts the black jacket tube of ∮ 250 high density polyethylene (HDPE)s, and its wall thickness is 6mm; Interior pipe 11 adopts the boiler steel high pressure seamless pipe of ∮ 76 * 8; FlexbleJoint 13 is a stainless steel welded type bellows, an end band edge plate; Seal glass silk cloth 7, ectonexine super glass wool 8,9 are all standard specification, and iron wire 10 adopts 16# standard iron wire.The material of globe joint part bulb 2, fittings body 14, gland 4 is the 20CrMo steel, and pressure ring 3, baffle ring 15 materials are the 2Cr13 steel, all carry out modifier treatment, sphere contact portion hard chrome plating; Sealing ring 16 usefulness soft graphites are made.Bulb 2 is ∮ 76 * 8 pipe fittings of a long 132.5mm, can rotate in 30 ° of garden cone angles, and it is 100mm that the distolateral surface of one is spherical its external diameter in garden; Gland 4 is the garden dish of a back side band groove, is evenly distributed with 4 ∮ 16 driving holes on it, and the T shape screw thread of T140 * 4 is worn in the garden in the groove; Pressure ring 3 is a common garden annular, and baffle ring 15, sealing ring 16 are the garden ring that inner surface is a sphere; Fittings body 14 two ends in a tubular form, to take over end identical for external diameter and bulb 2 in the end, the centre is toroidal, front end garden face outward has the T shape screw thread that cooperates with garden face in gland 4 grooves.
The utility model adopts spherical movable joint, thermal insulation material and black jacket protective layer, can make things convenient for, effectively be used for steam injection process, greatly reduces steam injection pipeline and steel consumption, reduces cost for oil production. This kind annotated steam pipe can be by prefabrication, thereby, reduce the work on the spot amount, have also that weight is light, an easy construction, the advantage such as safe and reliable.
