Abstract
A heat insulation box for a pressure gauge of a steam injection oil well is applied to steam injection manifolds for petroleum heavy oil exploitation. A front half box body and a rear half box body are oppositely combined into a cuboid box body, the edges of the front half box and the rear half box are respectively fixed together by fixing lugs and bolts, heat insulation foam layers are disposed on the inner walls of the front half box body and the rear half box body, two semi-annular hoops are respectively fixed to the lower edges of the front half box body and the rear half box body and symmetric to each other, the semi-annular hoops fixed to the lower edges of the front half box are opposite to those fixed to the lower edges of the rear box body so as to form circular hoops, and pipeline holes are disposed on the box bodies and at the positions of the heat insulation foam layers which are opposite to the circular hoops. The heat insulation box has the advantages that the heat insulation box realizes heat insulation of the pressure gauge and an oil well sampling device by means of sufficiently using the temperature of an oil well pipeline, is fine in heat insulation effect and convenient in assembly and disassembly, can effectively prevent the pressure gauge and the oil well sampling device from being frozen and blocked in winter, and is applicable to steam pipelines of heavy oil wells or oil wells.
Description
Technical field
The utility model relates to heavy crude petroleum production technique field, and particularly thick oil filling steam manifold is the pressure meter incubator on the steam manifold.
Background technology
Because viscosity of thickened oil is big, to improve reservoir temperature to the oil reservoir steam in jection during exploitation, reduce viscosity of thickened oil.Superheated steam is injected in the oil reservoir from ground; pipeline and well head will bear high temperature and high pressure; high temperature can impact manometric certainty of measurement and application life; therefore viscous crude all installs condensate pipe additional with pressure meter device; crude oil or steam to high temperature play certain thermolysis; to reduce pressure meter temperature protection pressure meter, guarantee the accuracy of institute's measuring pressure.Installing condensate pipe additional causes the pressure meter device height to raise, exceed setting height(from bottom) in the common well head incubator, therefore thick oil well only wraps up wellhead assembly with the oil well muff, and pressure meter device is wrapped up with glass fibre thermal insulation material, reaches heat preservation effect.Have to pressure meter is exposed to the outside fully in order to observe the pressure variation, the pressure meter that is exposed to the outside will increase the heat waste of oil well.Use glass fibre thermal insulation material, operating personnel's health is had certain infringement, and be easy to be stained with greasy dirt and be difficult to clean, can't reuse after when workover treatment, removing, pollute the environment.In addition, in the winter of cold, the sampler of this muff and pressure meter device are exposed to the muff outside, when the oil temperature descends, will freeze stifled phenomenon, freezing pressure meter, or it is stifled to cause sampler to freeze, and can not get sample.
The utility model content
The purpose of this utility model is: a kind of steam-injected well pressure meter incubator is provided; can utilize the pipeline heat radiation that pressure meter is incubated, protection pressure meter and sampler do not freeze stifled phenomenon, reduce the oil well heat waste; reduce energy waste, reduce the influence of cold snap oil well production.
The technical solution adopted in the utility model is: steam-injected well pressure meter incubator, and mainly by later half casing, preceding half chests body, fixedly ear, bolt, semicircular clip, plastic-steel glass window and foam heat-insulation layer are formed.Before cuboid casing of the relative composition of half chests body with later half casing, at preceding half chests body and later half casing edge fixedly ear is arranged respectively, bolt passes fixedly that the ear fixing hole is fixed together preceding half chests body and later half casing; Inwall at preceding half chests body and later half casing is fixed with foam heat-insulation layer, and it is convenient observe pressure and operations such as replacing pressure meter, oil well sampling that a plastic-steel glass window, the effect of plastic-steel glass window are arranged on the preceding half chests body.It is characterized in that: the lower edge at preceding half chests body and later half casing is fixed with two semicircular clips respectively, and the semicircular clip is symmetrical; The semicircular clip that preceding half chests body lower edge is fixed is relative with the semicircular clip that later half lower box edge is fixed, and forms circular clip; There is the pipeline hole at casing and the foam heat-insulation layer position relative with circular clip.Manometric pipeline is installed is fixed in the circular clip, pressure meter is just in time aimed at the plastic-steel glass window, and the pipeline heat radiation of pressure meter both sides improves the temperature in the casing, can be incubated pressure meter.
Described plastic-steel glass window adopts folding to be fixed on the preceding half chests body.
What described foam heat-insulation layer adopted is polyurethane rigid foam plastic.
In order to improve the sealing between later half casing and the preceding half chests body, between later half casing and preceding half chests body opposite face, the sponge weather strip is arranged.
The beneficial effects of the utility model: the utility model steam-injected well pressure meter incubator, making full use of the oil pipeline temperature is incubated pressure meter and oil well sampler, have high insulating effect, mounting or dismounting convenient, can prevent effectively that pressure meter and oil well sampler from freezing stifled phenomenon winter, be specially adapted to use on the heavy oil wells of northern cold district or the oil well steam pipe line.

The specific embodiment
Embodiment 1: with a steam-injected well pressure meter incubator is example, and the utility model is described in further detail.
Consult Fig. 1 and Fig. 2.The utility model steam-injected well pressure meter incubator is mainly by later half casing 4, preceding half chests body 5, fixedly ear 1, bolt 3, semicircular clip 6, plastic-steel glass window 2 and foam heat-insulation layer 7 are formed.Before half chests body 5 and cuboid casing of later half casing 4 relative compositions, at preceding half chests body 5 and later half casing 4 edges six fixedly ears 1 are arranged respectively, bolt 3 passes fixedly that ear 2 fixing holes are fixed together preceding half chests body 5 and later half casing 4.Between later half casing 4 and preceding half chests body 5 opposite faces, the sponge weather strip is arranged.Be fixed with the foam heat-insulation layer 7 of 15 millimeters thick at the inwall of preceding half chests body 5 and later half casing 4, what foam heat-insulation layer 7 adopted is polyurethane rigid foam plastic.On the preceding half chests body 5 a plastic-steel glass window 2 is arranged, plastic-steel glass window 2 adopts foldings to be fixed on the preceding half chests body 5.
