Abstract
The utility model discloses equipment for using waste steam in thickened oil thermal recovery. The equipment is formed by connecting a steam jetting pump, a steam mixing chamber, a steam heat pump and a pressure sensing controller. High-temperature steam generates sucking force by the steam jetting pump; the waste steam in the thickened oil thermal recovery is automatically sucked to be mixed with the high-temperature steam in the steam mixing chamber to form medium-temperature steam; the medium-temperature steam is injected into a collecting and conveying system after being pressurized by the steam heat pump. The equipment is simple and low in cost, solves the problem of environment pollution caused by the emission of the waste steam, recovers the light oil component contained in the waste steam, and is good in energy-saving and environment-friendly effect, and the use amount of the high-temperature tracing steam in the thickened oil collecting and conveying process is reduced.
Description
Technical field
The utility model relates to exhaust steam in a kind of exhaust steam recycling equipment, particularly heavy crude heat extraction and utilizes equipment.
Background technology
In heavy crude heat extraction process, exhaust steam derives from steam injection well and oil reservoir is invaded bubble, condensed after heat diffusion, the oil returning out with viscous crude Produced Liquid, water, the gas of liquid mixture after surge tank produces the separation of liquid gas, not only there are composition, formation water, the formation rock mineral matter of steam injection, the composition of steam condensate, also have in viscous crude the toxic and harmful compositions such as light composition and hydrogen sulfide, sulfur dioxide, carbon dioxide, mercaptan, may also contain our temporary transient unmeasured composition.Off-gas flows amount is unstable, it is large to change between temperature 80-160 ℃, and lease tank is many, has caused serious environment pollution, threaten surrounding population and animal health safety, under the present situation of in-situ processing lack of water, conventional steam condensation method difficult treatment, air setting cost is high, deficiency in economic performance; And on the other hand, the temperature that the defeated needs of the collection of viscous crude are certain, adopts 300-350 ℃, mass dryness fraction 70% left and right high-temperature steam pipeline companion heat conventionally, larger to high-temperature steam waste like this; Therefore exhaust steam is mixed with high-temperature steam on a small quantity, directly enter gathering system, not only reduced the environment pollution of exhaust steam, the heat in exhaust steam of having gone back maximum using, has reclaimed the light oil composition in exhaust steam, has good recovery and utilizes effect.
Summary of the invention
The utility model object is to provide exhaust gas utilization equipment in a kind of simple and practical, heavy crude heat extraction process that recovery utilization rate is high.
The utility model solves its technical problem and is achieved through the following technical solutions:
In heavy crude heat extraction, exhaust steam utilizes an equipment, comprises that steam jet pump, steam chamber, steam heat pump, pressure sensing controller connect to form; Water jet pump is connected with high-temperature steam pipeline, steam chamber, exhaust steam gathering line respectively, and steam chamber is connected with steam heat pump, middle temperature steam pipe line.
In above-mentioned a kind of heavy crude heat extraction, exhaust steam utilizes equipment, on its high-temperature steam pipeline and exhaust steam gathering line, pressure sensor has all been installed.
In above-mentioned a kind of heavy crude heat extraction, exhaust steam utilizes equipment, and its steam chamber is closed container.
During a small amount of high-temperature steam process of the utility model utilization steam jet pump, produce suction force, exhaust steam in heavy crude heat extraction is pumped to steam chamber from storage tank, warm steam in formation, directly pump into gathering line, in its heat and exhaust steam, lightweight oil content peak discharge is recovered, and closed-loop operation has solved in exhaust steam the toxic and harmful emission problems such as hydrogen sulfide, i.e. energy-conservation environmental protection again, has also evaded wellblock and around personnel and other animals and plants security risks.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
The specific embodiment providing below in conjunction with accompanying drawing 1 is described further the utility model:
In a kind of heavy crude heat extraction, exhaust steam utilizes equipment, comprise that steam jet pump 1, steam chamber 2, steam heat pump 3, pressure sensing controller 4 connect to form, water jet pump 1 is connected with high-temperature steam pipeline 5, steam chamber 2, exhaust steam gathering line 6 respectively, and steam chamber 2 is connected with steam heat pump 3, middle temperature steam pipe line 7; On high-temperature steam pipeline 5 and exhaust steam gathering line 6, pressure sensor 4 has all been installed; When in high-temperature steam pipeline 5, high-temperature steam is through steam jet pump 1, aspiration end at steam jet pump 1 produces suction force, exhaust steam in suction exhaust steam gathering line 6, enter steam chamber 2 form in after warm steam, by steam heat pump 3, inject warm steam pipe line 7; When steam jet pump or equipment break down, high-temperature steam pipeline 5 and exhaust steam gathering line 6 can build the pressure, and pressure sensing controller 4 startups, close high-temperature steam and start gas sampling pipeline liberation port, guarantee device security.
