Abstract
The utility model relates to a detachable triple ram preventer heat preservation and heating device, which is a frost protective device of a triple ram used in the workover with pressure for an oil extraction water injection well in a severe cold area in the oil industry. The device is formed by fixing at least two heating units into a whole through a fastening bolt; each heating unit is fixed together to form a hollow cavity in the identical shape as that of the triple ram, so that the triple ram can be buckled therein; each heating unit is a shell body, a heat preservation layer is arranged on the inner wall of the shell body, an electric heating unit is mounted in the shell body, and a connecting member is arranged outside the shell body. The device can be detached conveniently; when an oil extraction water injection well stops work at night, the heat preservation and heating device is buckled and mounted outside the triple ram to heat and preserve the heat of the triple ram and ensure that the triple ram equipment can not occur frost accidents in the winter construction of the three oil fields in the northeast; when the operation is started the next day, the device can be conveniently detached from the triple ram for normal construction, thereby greatly improving the workover construction efficiency.
Description
One, technical field:
The utility model relates to petroleum industry oil-extracting and water-injecting well extremely frigid zones band and press the freezing protector of workover treatment with three flashboards, specifically is detachable three flashboard heat insulation and heating equipments.
Two, background technology:
Press in the workover treatment at petroleum industry oil-extracting and water-injecting well band, three flashboards are main thermal components exposed on the well mouth of oil well.Because northeast three elephants all are in the exploitation middle and later periods, oil-extracting and water-injecting well well-repairing work amount is very big, need proceed construction in season in severe winter.By day in the well workover construction, remove work such as oil pipe and can guarantee that the water in underground water and the ground installation fully circulates, do not cause equipment such as three flashboards freezing.Evening, when stopping to construct, cold weather, ground installation heat radiation is very fast, is easy to make the water in the equipment such as three flashboards to freeze.For preventing that three flashboards from freezing, after workover treatment stops, at first bleed off the liquid that is higher than three flashboard positions, but inevitable residual fraction liquid in this valve member of three flashboards, after these liquid are freezing, still cause three flashboards normally to open and close, make second day and continue constructional difficulties, get rid of freezing fault and need several hrs.Therefore be badly in need of a kind of freezing protector of three flashboards that can heat tracing influence normal workover treatment again of development.
Three, summary of the invention:
The purpose of this utility model provides a kind of detachable three flashboard heat insulation and heating equipments, and this detachable three flashboard heat insulation and heating equipments are used for solving three flashboard equipment constructs in the winter time, and when stopping operation the problem of freezing accident takes place night.
The technical scheme that its technical problem that solves the utility model adopts is: this detachable three flashboard heat insulation and heating equipments are fixed together by fastening bolt by at least two heating monomers and form, it is identical with the profile of three flashboards that each heats the be fixed together shape of the cavity that the back forms of monomer, three flashboards can be fastened on wherein; Described heating monomer is a housing, and inner walls has insulation layer, and electrical heating elements is installed in the housing, and housing has connector outward.
The heating monomer of such scheme be about two.
Electrical heating elements in the such scheme is the infrared radiation heating pipe.
Beneficial effect:
1, the utility model is connected and fixed by dismountable heating monomer and forms, easy accessibility, when night, the well workover of oil-extracting and water-injecting well stopped operation, the utility model fastening is installed in outside three flashboards, can be to three flashboard heat tracings, freezing accident can not take place northeastward in the three elephant winter construction in the three flashboard equipment that guarantee; And when beginning operation in second day, can easily the utility model be disassembled from three flashboards, carry out normal construction, improve the well workover efficiency of construction widely.
2, through the advance copy utility model, continue heat tracing after 14.5 hours at night, 25 ℃ of the corresponding three flashboard measuring point temperature of close three flashboard heat insulation and heating equipments have reached stable state, far above freezing temperature.On second day daytime, three flashboards can normally use, and illustrate that the utility model has reached the heat tracing effect, can satisfy field requirement.

Five, the specific embodiment:
In conjunction with Fig. 1, Fig. 2, shown in Figure 3, in the present embodiment, this detachable three flashboard heat insulation and heating equipments are installed together by fastening bolt 7 make-ups by left and right two heating monomers (1,2), left and right two heating monomers are housing, inner walls has insulation layer 3, electrical heating elements is installed in the housing, and housing all has connector 6 outward.The inwall of left and right heating monomer (1,2) all designs according to the appearance and size of three flashboards, left side heating monomer 1 is buckled together with right 2 pairs of monomers of heating, fastening bolt 7 is by the through hole of connector 6, left and right two heating monomers (1,2) can be fixed together, the shape of the cavity 5 that the two back that is fixed together forms is identical with the profile of three flashboards, three flashboards can be fastened on wherein.Because three flashboards have the turnover pipeline,, be the pipeline slot milling so left and right two heating monomers (1,2) connecting portion is in front reserved one section step-like space.
Electrical heating elements in the present embodiment is an infrared radiation heating pipe 4, and this heating tube 4 is a U type heating tube, and these heating tube 4 terminals stretch out from installing inside, by power input socket 8 that is arranged in two heating monomer tops and cable 9 power supplies.Certainly the electrical heating elements in the utility model is not limited to infrared radiation heating pipe 4, and the electrical heating elements of other kinds can.
The heat insulating material that respectively heats monomer insulation layer 3 in the present embodiment is selected pyroceram fibre for use, but is not limited to this.
Left and right heating monomer (1,2) adopts corrosion resistant plate in the present embodiment in heating tube 4 positions, and the galvanized sheet iron manufacturing is adopted in other position.
The utility model can also be three or four with the heating monolithic design, heats monomer accordingly and snaps together formation by fastening bolt 7.
The utility model is designed to traditional heater dismountable, when night, the well workover of oil-extracting and water-injecting well stopped operation, the utility model fastening is installed in outside three flashboards, fastening with fastening bolt 7, connect then electrical distribution system is installed, start diesel-driven generator,, make three flashboard equipment also freezing accident can not take place at chill night to three flashboard heat tracings; And when beginning operation in second day, can easily the utility model be disassembled from three flashboards, carry out normal construction, improve the well workover efficiency of construction widely.
