Hang on discharging tube hook, close sample cock, open draining valve, in the crude oil sample of sampler cavity, through discharging tube stream
Enter sample bucket, the oil-well sampling device realizes Oil-gas Separation, solves natural gas and assembles in heapstead, and security risk is high to ask
Topic.But the oil-well sampling device is complicated, parts are more, to be grasped during crude oil sample is collected with sample bucket
Two valves of sample cock and draining valve are controlled, sampling procedure is more, and operation is not easy.
Utility model content
The purpose of the utility model separate type Samper for oil well is to provide a kind of separate type Samper for oil well solve
Existing oil-well sampling device is complicated, and manipulation valve quantity is more, and the operating procedure that crude oil sample is collected is more, operation is not easy asks
Topic.
To achieve the above object, the technical scheme of the utility model separate type Samper for oil well is：A kind of oil well sampling
Device includes shuttle and gas-oil separation joint, and gas-oil separation joint is provided with feed tube and blast pipe, the shuttle
The sampling bottle that opening is provided with by top is formed, and sampling bottle and gas-oil separation joint is are detachably connected, sampling bottle and Oil-gas Separation
The junction of both joints is provided with sealing structure.
The gas-oil separation joint is the cavity cylinder of lower ending opening, and the oil gas with stomata is provided with the middle part of cavity cylinder
Gas-oil separation joint is separated into two chambers by separation dividing plate.
The gas-oil separation joint lower port is provided with connection screw thread, and the sampling bottle is connect by connection screw thread and Oil-gas Separation
Head is detachably connected.
The Samper for oil well also includes being used for the bottle cap that closure is located in sampling bottle opening.
The L-shaped bending in feed tube top, bottom reach in sampling bottle but do not contact sampling bottle bottom of bottle.
The feed tube mouth of pipe has the screw thread with the supporting connection of sample cock.
The blast pipe is inclined on gas-oil separation joint.
The blast pipe is connected with for the guide pipeline outside gas export heapstead.
The beneficial effects of the utility model are：Because sampling bottle and gas-oil separation joint are dismountable connection, by this
Samper for oil well reduces the step of crude oil sample is collected, decreases and sampled while realizing that oil gas is automatically separated
The quantity of valve is manipulated in journey, only need to control production tree sample cock, it is possible to realize sampling process, simple in construction, operation side
Just.

Embodiment
The embodiment of the utility model separate type Samper for oil well is described further below in conjunction with the accompanying drawings.
The specific embodiment of the utility model separate type Samper for oil well, as shown in Figure 1 to Figure 2, by sampling bottle 4 and oil
Gas separating joint 3 is formed, and sampling bottle 4 forms shuttle, and gas-oil separation joint is the cavity cylinder of lower ending opening, and oil gas divides
It is tightly connected from the lower port of joint 3 with the bottleneck of sampling bottle 4 by screw thread, there is feed tube 5 and blast pipe 2 on gas-oil separation joint 3,
There is the Oil-gas Separation dividing plate 8 with stomata at middle part in gas-oil separation joint 3, naturally it is also possible to and it is hydrocarbon filter net, the top of feed tube 5
L-shaped bending, bottom are reached in sampling bottle 4 through Oil-gas Separation dividing plate 8, and oil and gas import 6 is machined with and production tree sample cock
The screw thread of supporting connection, blast pipe 2 are inclined on gas-oil separation joint 3, and exhaust outlet 1 machined to fall with tapered sealing
Angle connects plastic flexible pipe（It is not drawn into figure）.
When carrying out oil well sampling operation, oil and gas import 6 is connected by screw thread with production tree sample cock, sampling bottle 4 with
Gas-oil separation joint 3 is tightened with screwed connection, opens sample cock, and oil gas enters sampling by the oil and gas import 6 of sampler
Bottle 4, under gravity, liquid sinks are gathered in the bottom of sampling bottle 4, because gas density is small, into sample sampling bottle 4 after upwards
Motion, gas carry droplet by gather stomata Oil-gas Separation dividing plate 8 when, part droplet hit Oil-gas Separation every
Plate 8 is simultaneously separated, and completes to separate for the first time, the gas for carrying part droplet passes through the stomata on Oil-gas Separation dividing plate 8
Into secondary separation room 7, the droplet that gas carries collides with the inwall of gas-oil separation joint 3 again, small under effect of inertia
Drop is separated from gas again, and droplet is gathered into larger oil droplet, passes through bottom Oil-gas Separation dividing plate 8 under gravity
Stomata enter sampling bottle 4 and complete second of oil gas separation, the natural gas after separation passes through exhaust outlet 1 and plastic flexible pipe（Figure
In be not drawn into）It is discharged into the air outside heapstead.After sampling, sampling bottle 4, sampling bottle 4 are laid down after closing sampling gate
With original supporting bottle cap sealing, sampling operation is completed.Because sampling bottle 4 and gas-oil separation joint 3 are dismountable, sampling bottles
After 4 dismountings, a new sampling bottle can be installed, do not influence sub-sampling again, operate high-efficient simple.
In other embodiments, the connection of sampling bottle and gas-oil separation joint can also other dismountable connected modes,
Such as flange connection.In addition, sampling bottle can also be transparent container with a scale, can intuitively recognize in sampling process
The collection situation of original sample, according to the amount required for chemical examination detection, realize the quantitative collection to crude oil sample.
Using the utility model Samper for oil well, the natural gas in crude oil is separated, natural gas is through plastic flexible pipe
It is discharged to outside heapstead, the natural gas separated is discharged heapstead, the aggregation of natural gas will not be caused；Sampling bottle is directly collected
Crude oil sample, reduce the operating procedure that crude oil sample is transferred to sample bucket during sample collection, decrease and sampled
The quantity of valve is manipulated in journey, structure is simpler, and operation is more convenient.
