Abstract
The utility model relates to a thermal insulation thick oil tank which is applied in oilfield thick oil exploitation and used during the production of thick oil with medium-high viscosity by a temporary put-to-production well. The thermal insulation thick oil tank mainly comprises a square tank body and electric heaters, wherein the square tank body is a cubic container welded by a steel plate, two groups of the electric heaters are fixedly arranged at the bottom in the square tank body, the power supply connection end of the electric heaters penetrates the wall of the square tank body and is fixed on the wall of the square tank body, and seal rings are arranged between the electric heaters and the wall of the square tank body; and pipeline joints are welded at the upper part of the square tank body. The thermal insulation thick oil tank has the effects that the electric heating way is adopted for providing heat for the thick oil in the 30m3 thermal insulation square tank, so that the difficult problems of wellhead back pressure increase, difficult crude oil loading and unloading and the like during the production of the thick oil with the medium-high viscosity by the temporary put-to-production well are solved, and the stable and high-efficient production of the well are ensured.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly viscous crude oil production is a kind of at middle and high viscosity viscous crude interim brought in well production difficulty and design-calculated is suitable for the insulation viscous crude jar that well head is closely put.
Background technology
At present, thermal recovery Pressure Curve in Oil Testing Well such as viscous crude prospect pit, appraisal well, control well owing to there are not production systems such as perfect companion's heat, collection is defeated, often adopt 60m
3Round can faces the production. art production of reborning, and promptly oil well produced crude oil generally enters 60m by flowline
3Round can, entrucking roping then.
Face for the viscous crude of middle and high viscosity and to drown oneself in a well 60m
3Round can faces and faces following difficulty when the production. art of reborning is produced in the winter time:
1, because 60m
3Round can and tank base volume are bigger, for security consideration, generally are arranged in the position far away apart from well head, and the whole piece oil outlet pipe is about 50 meters.Winter, the oil temperature descended in the pipe along with temperature reduces, and viscosity of crude sharply increases, and causes along the journey crushing excessive.For the heavy oil wells of middle and high viscosity, crude oil flows in 50 meters long pipelines, is respectively 2.5MPa, 7.0MPa along the journey crushing.Because excessive along the journey crushing, oil well output sharply descends even stops production---crude oil can't flow in the pipe.
2, jar interior crude oil entrucking in summer is comparatively smooth, but a winter to cold, along with the decline of temperature, viscous crude flowing power variation.Even 60m
3Electric heater is set to the limit (399 ℃) with heating-up temperature in the round can jar, and the oil that flows out from flow line stream temperature can only reach about 40 ℃.Loading-unloading vehicle crude oil need spend 5～6 hours in the time of the most difficult, and efficient is extremely low, has had a strong impact on the shipping work of crude oil.
Owing to face above difficulty, 60m
3Round can faces the production. art of reborning can not be satisfied middle and high viscosity viscous crude and face production in the winter demand of drowning oneself in a well.
For the thermal recovery Pressure Curve in Oil Testing Well of indivedual extra-high-speed viscosity, even in summer, reduce gradually with the oily temperature of the prolongation of production time behind the vapour of showwing loving care for, viscosity of crude increases gradually, and the pipeline internal resistance rises, and enters 60m by long flowline
3Round can production also can encounter difficulties.
The utility model content
The purpose of this utility model is: a kind of insulation viscous crude jar is provided, can realizes the interim brought in well of middle and high viscosity viscous crude (limit prospect pit, appraisal well, the control well) production of recovering the oil under companion heat, the incomplete situation of gathering system.
The technical solution adopted in the utility model is: insulation viscous crude jar, mainly form by square tank and electric heater, side's tank is the cube shaped container of steel plate welding, it is characterized in that: the bottom in square tank is fixed with two groups of electric heaters, on the power connection end side of the passing tank wall of electric heater and the wall of the side's of being fixed on tank, between electric heater and the square tank tank skin seal ring is arranged; Top at square tank is welded with pipe joint, and pipe joint can associated line.Pipeline is connected with christmas tree, can realize the production of recovering the oil under companion heat, the incomplete situation of gathering system of the interim brought in well of middle and high viscosity viscous crude.
For square tank conveniently moving, be fixed with sledge in the bottom of square tank.
For the insulation of square tank, be enclosed with the composition silicate felt at the outside face of square tank, the outside of composition silicate felt is surrounded by galvanized iron and makes protective cover.
The volume of described side's tank is 30m
3
The beneficial effects of the utility model: the utility model insulation viscous crude jar, the employing Electric heating is 30m
3Insulation side's jar interior viscous crude provides heat, efficiently solves middle and high viscosity viscous crude and faces the difficult problems such as wellhead back pressure raises when producing, crude oil loading and unloading difficulty of drowning oneself in a well, and guarantees that this type of well can be stablized, High-efficient Production.
Description of drawings
Fig. 1 is the utility model insulation viscous crude jar structure scheme drawing.
Among the figure, 1. electric heater, 2. square tank, 3. oil line, 4. christmas tree.
The specific embodiment
Embodiment 1: with an insulation viscous crude jar is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model insulation viscous crude jar mainly is made up of square tank 2 and electric heater 1, and square tank 2 is cube shaped containers of steel plate welding.Side's tank 2 outer wall length are 7m, and width is 3m, is 1.45m highly, and volume is about 30m
330m
3Insulation side's jar and oil field 60m commonly used
3Round can is compared, and volume is less, effective volume 30m
3, outside dimension is also small and exquisite relatively, is convenient to the well head low coverage and puts and do not influence remedial work.
