Abstract
The utility model relates to a gas-liquid separating device for oil well casing associated gas and specifically relates to a backflow type casing associated gas separator. The backflow type casing associated gas separator is characterized in that a pipe body is an upright steel pipe and includes an upper end sealed by an inner blind plate and a lower end connected with a clamp via an elbow and a gas inlet pipe and is integrally L-shaped; the top of the pipe body is provided with a gas outlet pipe; the upper portion of the pipe body is provided with a valve and a pressure gage; the middle-upper portion in the pipe body is longitudinally provided with three separating umbrellas; and the vertical distance between the two adjacent separating umbrellas ranges from 200 to 300 mm. The backflow type casing associated gas separator has following beneficial effects: condensed liquid of oil well casing associated gas is well separated to satisfy the demand for processing associated gas; externally-discharged pollutants are not produced and condensed liquid is guided to flow back to a wellhole; external emission is avoided and environmental pollution is further prevented; an oil-gas separator is prevented from stealing gas condensate and natural gas; and burglar resistance and safety performance is improved.
Description
Technical field
The utility model relates to a kind of gas-liquid separation equipment of oil well casing associated gas.
Background technology
Heating furnace for oil well is generally to adopt oil well casing associated gas combustion heating to heat up, and winter temperature is low, and casing associated gas very easily condensation forms condensed liquid.On oil field at home casing associated gas flow process pipeline, there is gs-oil separator, the eliminator that generally adopts specialized factory to produce, this eliminator is mostly the above cylinder of φ 300mm, volume is more than 100 liters, design pressure 2.5MP, is provided with the safety attachments such as safety valve, belongs to pressure vessel.Must be by the professional production manufacturer production with corresponding qualification according to national regulation pressure vessel, in use, must regularly test, every year safety attachment is carried out to verification, by have pressure vessel operate card staff operate, increased management of safe operation amount and work difficulty.
Discharge opeing atmospheric valve is arranged at the bottom of existing eliminator, and isolated condensed liquid need to discharge sky outward by artificial timing, easily causes environment pollution, and lawless person also can steal gas, stolen by atmospheric valve, has major safety risks.If flow process pipeline is easily stopped up in emptying in winter not in time condensed liquid.Existing separator volume is bigger than normal, and pressure rating is high, is not suitable with low permeability oil field associated gas oil-air pressure low, the present situation that associated gas quantity is few.
Summary of the invention
The purpose of this utility model is to provide a kind of reverse-flow type casing associated gas eliminator, the problem existing to solve prior art.
The utility model is mainly made up of body, air inlet pipe, escape pipe, valve and pressure meter, the technical scheme that solves its technical problem employing is that the utility model is made up of clip, air inlet pipe, body, interior blind plate, elbow, separation umbrella, escape pipe, valve and pressure meter, this reverse-flow type casing associated gas eliminator body is upright steel pipe, upper end has interior blind plate to bind, lower end is by elbow, air inlet pipe and clamp connection, and entirety is L-type.Body welded top has escape pipe, and body top is provided with valve and pressure meter.In body, middle and upper part longitudinally arranges several and separates umbrella, separate umbrella top end and have 8-12mm circular hole, separate full skirt portion diameter and be less than internal diameter of tube body 8-10mm, be connected with inboard wall of tube body by several solder joints, making to separate full skirt portion and inboard wall of tube body has a circle 3-5mm gap.Adjacent two separate umbrella vertical distance between 200-300mm, can increase and decrease and separate umbrella number according to the oil well casing situation of giving vent to anger, and meet the needs that separate associated gas condensed liquid.
Adopt good effect of the present utility model to be:
1, this device can be good at the condensed liquid of separating oil casing associated gas, meets associated gas processing demands.
2, reverse-flow type casing associated gas eliminator can not produce outer pollution discharging, condensed liquid guiding can be flowed back in pit shaft, and no longer empty with the outer discharge of artificial timing, not outer row, does not exist environment pollution.
3, stop lawless person and steal condensate, natural gas from gs-oil separator.
4, simple in structure, do not belong to pressure vessel, reduce pressure vessel safety management workload, safe and reliable to operation.
5, guarantee that winter, condensed liquid did not stop up flow process pipeline, ensure the operation of heating furnace for oil well normal combustion, and it is low to adapt to the existing associated gas oil-air pressure of low permeability oil field, the present situation that associated gas quantity is few, overcomes the large problem of existing eliminator safety management difficulty.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model A-A partial enlarged drawing;
In figure, 1 clip, 2 air inlet pipe, 3 bodys, 4 pressure meters, 5 valves, 6 interior blind plates, 7 escape pipes, 8 separate umbrella, 9 elbows.
8-1 circular hole, 8-2 solder joint, 8-3 gap in Fig. 2.
Detailed description of the invention
As shown in the figure; This reverse-flow type casing associated gas eliminator body 3 is upright steel pipe, and upper end has interior blind plate 6 to bind, and lower end is connected with clip 1 by elbow 9, air inlet pipe 2, and entirety is L-type.Body 3 welded top have escape pipe 7, and body 3 tops are provided with valve 5 and pressure meter 4.Several are longitudinally set in the interior middle and upper part of body 3 and separate umbrella 8, separate umbrella 8 top ends and have 10mm circular hole 8-1, separate umbrella 8 skirt section diameters and be less than internal diameter of tube body 8mm, be connected with inboard wall of tube body by 3 solder joint 8-2, making to separate umbrella 8 skirt sections and inboard wall of tube body has a circle 4mm gap 8-3; Adjacent two separate umbrella 8 vertical distances between 200-300mm, can increase and decrease and separate umbrella number according to the oil well casing situation of giving vent to anger, and meet the needs that separate associated gas condensed liquid.
When work, first associated gas enters separator after overflowing from oil well casing, and casing gas, in uphill process, and separates umbrella contact and carries out cold solidifying ﹑ collision and separate, and isolated condensed liquid, because Action of Gravity Field is along tube wall to dirty, finally flows back in oil well casing.Purer associated gas enters heating furnace for oil well burning by the pipeline of giving vent to anger.
