Description
Technical field
The present invention relates to a kind of surge tank, particularly relate to a kind of modified Oil-gas Separation surge tank.
Background technology
Produce at present natural gas tolerance adjustable range little.In actual production, in some oil recovery in initial oilfield exploitation or the high oil field of oil-gas ratio, the isolated tolerance of Oil-gas Separation surge tank on supercharging point or block station is larger, is far longer than website and produces and gas for domestic use needs.Unnecessary gas is due to the restriction of existing mixed transportation process, after cannot again mixing again with crude oil, carry, and most of website is not laid the pipeline of transport gas, unnecessary natural gas almost all adopts to ignite the torch and burns, and causes a large amount of wastes of fuel and environment pollution.Meanwhile, because a large amount of gases in upstream stations crude oil separate, cause the crude oil of downstream website can not isolate enough casing-head gas and meet heating and other need of productions.In isolated natural gas, contain in addition a large amount of steam and high-carbon light hydrocarbon component.Carry with pipeline, along with temperature reduces, easily become mutually liquid phase from gaseous state in the winter time, blocking pipeline, impact is normally produced.In the time processing frozen block pipeline, because light hydrocarbon component burning-point is low, easily make Light hydrocarbon burner, cause burn employee's accident.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of simple in structurely, can regulate gas production, reduce the component of steam and high-carbon lighter hydrocarbons in the natural gas of separating, improve the modified Oil-gas Separation surge tank of natural gas quality.
In order to address the above problem, the technical solution used in the present invention is:
A kind of modified Oil-gas Separation surge tank, comprise tank body, acceptor of energy, upper buffer board, demister and gasotron, on tank wall, be provided with main oil-in, auxiliary oil-in, gas outlet and oil export, it is characterized in that: also comprise three way cock and lower buffer board, in tank body, be provided with acceptor of energy, upper buffer board, lower buffer board, demister and gasotron, described three way cock one port is for oil-feed, two other port of described three way cock is connected with auxiliary oil-in with main oil-in by pipeline respectively, described main oil-in rear end is provided with acceptor of energy, buffer board on being provided with below acceptor of energy, rear end at upper buffer board is provided with demister, described demister rear end is provided with gasotron, on the tank body of gasotron rear end, be provided with gas outlet and oil export, be provided with lower buffer board in auxiliary oil-in rear end, the medium that described lower buffer board flows out leads to oil export, upper end in gas outlet is provided with condensation separator, described condensation separator is connected with tank body by return duct.
Aforesaid a kind of modified Oil-gas Separation surge tank, is characterized in that: be provided with mist eliminator in gasotron rear end.
Aforesaid a kind of modified Oil-gas Separation surge tank, is characterized in that: before tank body, side roof part is provided with main oil-in, is provided with auxiliary oil-in in bottom, tank body front side.
Aforesaid a kind of modified Oil-gas Separation surge tank, is characterized in that: be provided with gas outlet at rear portion, tank body top side, be provided with oil export in tank body bottom rear, described gas outlet bottom is connected with mist eliminator.

Brief description of the drawings
Fig. 1 is modified Oil-gas Separation surge tank structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of modified Oil-gas Separation surge tank, comprise tank body 1, acceptor of energy 2, upper buffer board 3, demister 4, gasotron 5, mist eliminator 6, three way cock 7, lower buffer board 8 and condensation separator 9, be provided with main oil-in 10 at the front side roof part of tank body 1, be provided with auxiliary oil-in 11 in bottom, tank body front side.Be provided with gas outlet 12 at tank body 1 rear portion, top side, be provided with oil export 13 in tank body bottom rear.In tank body 1, be provided with acceptor of energy 2, on buffer board 3, lower buffer board 8, demister 4, gasotron 5 and mist eliminator 6.
Described three way cock 7 one ports are for oil-feed, described three way cock 7 two other ports are connected with auxiliary oil-in 11 with main oil-in 10 by pipeline respectively, described main oil-in 10 rear ends are provided with acceptor of energy 2, below acceptor of energy 2, be provided with buffer board 3, be provided with demister 4 in the rear end of upper buffer board 3, described demister 5 rear ends are provided with gasotron 5, on the tank body 1 of gasotron 5 rear ends, be provided with gas outlet 12 and oil export 13, be provided with lower buffer board 8 in auxiliary oil-in 11 rear ends, the medium that described lower buffer board 8 flows out leads to oil export 13, upper end in gas outlet 12 is provided with condensation separator 9, described condensation separator 9 is connected with tank body 1 by return duct.Described gas exports 12 bottoms and is connected with mist eliminator 6.In tank body 1, be provided with the heat(ing) coil for heated air.On tank body 1, be provided with safety valve 14.On tank body 1, be provided with the manhole 15 that convenient operation personnel enter.
On the surge tank of original structure, increase a three way cock 7 and an auxiliary oil-in 11, utilized three way cock 7 spool positions, regulated the oil mass of main oil-in 10 and auxiliary oil-in 11.Auxiliary oil-in 11 directly with surge tank 1 bottom UNICOM, the oil of main oil-in 10 passes through acceptor of energy 2, upper buffer board 3 etc., realizes Oil-gas Separation; The oil of auxiliary oil-in 11 enters after tank body 1, and the little a part of natural gas of a natural separation, by regulating three-way valve 7 spool positions, realizes the adjustment of surge tank gas production.
Increase a condensation separator 9 at surge tank gas outlet, Main Function is: the natural gas that condensation contains steam and high-carbon light hydrocarbon component, after condensation, part steam liquefy water, high-carbon light hydrocarbon component liquefy lighter hydrocarbons, these liquid parts rely on Action of Gravity Field, flow back in tank body 1.After simple like this its processed, the steam that natural gas contains and high-carbon light hydrocarbon component major part can be removed, thereby the component of the liquefy phase of easily condensing in minimizing natural gas improves its quality.
At one group of heated by natural gas coil pipe of the interior increase of tank body 1, when winter operation, after the natural gas of condensation after separating can being heated again, carry and arrive at a station in interior natural gas line, need for the production of heating.
In sum, modified Oil-gas Separation surge tank of the present invention, in the time of summer operation, regulating three-way valve 7, makes crude oil part enter surge tank by auxiliary oil-in, and gas production reduces, and the unnecessary natural gas of burning does not so just need to ignite the torch.Winter operation, due to condensation separator 9 being installed on surge tank, the steam in natural gas separates after being condensed with high-carbon light hydrocarbon component major part, needs everyday pressure cylinder to put the mixture of water and lighter hydrocarbons in the past, only needs weekly regular discharge once now.By the improvement to Oil-gas Separation surge tank, realize the adjusting of gas production, unnecessary natural gas is dissolved in crude oil, is not separated, and is transported to the website in downstream with pump, and then separates, for heating, generating and production liquefied gas.In addition by the improvement to surge tank gas flow process, reduce the component of steam and high-carbon lighter hydrocarbons in the natural gas of separating, improve the quality of natural gas.
