Description
Affiliated technical field
The utility model relates to the well mouth of oil well insulation protective cover of a kind of oil exploitation ground fuel delivery device, is applicable to the insulation protection of well mouth of oil well ground " production tree " device.
Background technology
Ground, oil field " production tree " device is interconnected to constitute with clip and clip head by sleeve pipe, oil pipe, petroleum pipeline, valve member, big or small four-way, wellhead sealing device etc., because of the outer appearance tree, is commonly called as " production tree " device.
The insulation of well mouth of oil well ground " production tree " device that extensively adopts at present is with felt exposed part to be wrapped up twining glass fabric again, for preventing rain erosion, the brushing paint repeatedly on the glass fabric surface, in wrapping glass fabric process, often cause workman's hand, arm, facial fine hair hole is penetrated by glass fiber, cause workman's skin trauma and severe anaphylactic reaction, at workover, the inspection pump, during operations such as well-flushing, these binders influence operation again, these binders are all cut dismounting, after finishing, wraps up construction operation brushing paint more again.This traditional heat preserving method heat insulation effect is poor, and promptly cost of idleness is not easy to operation again, also causes workman's skin trauma, and the discarded back of the binder of dismounting is without any recovery value and be difficult for degraded, becomes industrial refuse, causes environment pollution.In the oil extraction process, ground " production tree " device is taked suitable insulation measure, its objective is in order to keep crude oil after ground, not reduce its flow behavior from the depths, stratum, if temperature reduces viscosity of crude and increases thereupon, the downhole pump draw resistance increases, the oil well pump pump efficiency decreases, the also corresponding reduction of oil yield.Deficiency at the prior art existence, the purpose of this utility model provides a kind of well mouth of oil well insulation protective cover, this well mouth of oil well insulation protective cover has adopted heat insulating material and complex heat-preservation measure, have high insulating effect, easy accessibility, and can reuse, reduce cost, alleviate labor strength, non-environmental-pollution, there is sleety weather to prevent the barrier propterty of seepage.So winter is taked effectively to well mouth of oil well " production tree " device that heater by service is even more important in northern oil field.
Summary of the invention
The deficiency that traditional well head insulation protector security performance is low, heat insulation effect is poor in order to overcome, environment pollution can not be reused, easily be caused to complicated operation, cost height, the utility model provides a kind of well mouth of oil well insulation protective cover, this well mouth of oil well insulation protective cover not only has high insulating effect, safe in utilization, non-environmental-pollution, and easy accessibility, reusable, any surface finish, cleaning is convenient, beautifies the well site environment.
The technical scheme that its technical problem that solves the utility model adopts is: constitute three layers of complex heat-preservation measure by high strength glass outer steel shell, thermal insulation material liner, insulated fire coating, effectively contained the thermal loss that conduction of heat, heat radiation, thermal convection current cause.Cavity shape and well head " production tree " the device profile of thermal insulation material liner that scribbles the insulated fire coating is consistent.Structurally adopt two parts combination up and down, every part is two lobe formula structures.Joint between the upper and lower inserts top compactness edge cover combination by bolt by the bottom, the purpose that adopts this structure be for dismounting when the construction operation easily, easy for installation.On well mouth of oil well insulation protective cover, be shaped on oil pipe control valve bore, sleeve pipe control valve bore, middle total valve opening in advance, its aperture and position and well head " production tree " device valve consistent size.The joint portion that oil transportation pore, sleeve pipe oil gas pore, the end send out the hole blue, wellhead sealing device connecter hole, casing pressure detect the hole, oil pipe metrology and measurement hole is located at per two lobes insulation protective cover respectively, establish half hole on every lobe, pitch-row and position and " production tree " device are consistent.Well mouth of oil well is incubated protective cover is installed on well head " production tree " device, not only have good heat insulation effect, and have the barrier propterty of sleety weather leakproof with after the bolt.The well head that has " production tree " device does not have middle main valve, therefore, can adjust size H as required, is that well head " production tree " device of various height dimensions all can be supporting with it.Case surface is bright and clean, and cleaning is convenient, and case surface has the antiultraviolet material in case outdoor sunlight corrodes to prolong the persistence on surface.
The beneficial effects of the utility model are: have high insulating effect, mounting or dismounting convenient, sturdy and durable, reduce cost, alleviate that labor strength, safety well also can be reused, non-environmental-pollution, have the barrier propterty of sleety weather leakproof.
