Rear oil well there will be the situation that oil well interval is fuel-displaced, and it is the most fuel-displaced that staff is frequently encountered oil well when going oil well to be sampled
Situation, sampling operation just cannot be carried out, and makes staff futile.
Seeing shown in Fig. 1 to Fig. 3, this utility model provides a kind of producing well sampler, and this producing well sampler includes
Storage sampling mechanism 10, storage sampling mechanism 10 is connected for fixing with external pipe, specifically, stores sampling mechanism 10
Including storage organization 12 and the sampling structure 11 that is connected with storage organization 12, storage organization 12 is used for storing material to be sampled, takes
Spline structure 11 is for opening to be sampled by storage organization 12.
During work, material to be sampled in external pipe is stored by storage organization 12 at any time, when staff needs exterior tube
When material to be sampled in road is sampled, open storage organization 12 by sampling structure 11, by storage in storage organization 12
Material to be sampled is released and is sampled.
Even if during external pipe is in gap conveying material to be sampled, producing well sampler of the present utility model can be external
The material to be sampled that in portion's pipeline, interval flows out stores, as long as staff went depositing in this utility model every a period of time
Storage structure 12 is sampled, and efficiently avoid the problem that the sample time of existing sampler is difficult to control.
As in figure 2 it is shown, be sequentially connected with according to fuel-displaced direction on the external pipe that connected of producing well sampler of the present utility model
There is oil well pump 30, produce valve port 40, resistance oil nozzle sleeve 50, Pressure gauge 60, multifunction valve 70 and back-pressure valve 80, certainly, this reality
Being connected to other kinds of external pipe with novel producing well sampler can also.
Producing well sampler in this utility model also includes that interconnecting part 20, interconnecting part 20 are used for connecting external pipe and storage knot
Structure 12.During work, by interconnecting part 20, the material to be sampled in external pipe is incorporated in storage organization 12, and by unnecessary
Material to be sampled be reintroduced in external pipe.
Specifically, the storage organization in this utility model is bucket.
Controlling opening and closing of storage organization 12 for convenience, the sampling structure 11 in this utility model includes probe tube 111
With sampling valve 112, probe tube 111 is arranged on the bottom of bucket, and sampling valve 112 is arranged on probe tube 111.
During producing well works, sampling valve 112 is closed, thus ensures that the storage organization 12 in this utility model is right
Material to be sampled stores, and when needs are sampled operation, open sampling valve 112, will be stored in storage organization 12
Fluid takes out, thus completes sampling operation.
Specifically, the interconnecting part 20 in this utility model includes inflow pipeline 21 and flowline 22, the of inflow pipeline 21
One end is connected with external pipe, and the second end of inflow pipeline 21 is connected with bucket, the first end of flowline 22 and exterior tube
Road is connected, and the second end of inflow pipeline 21 is connected with bucket.
During work, the material in external pipe, the material in oil pipe flows into storage organization 12 from inflow pipeline 21 specifically,
When the material to be detected in storage organization 12 is too much, the most unnecessary material to be detected passes through flowline 22 from storage organization 12
It flow back in external pipe, thus prevent storage organization 12 too much and swollen bad due to material to be detected.
In order to the material making sampling is more accurate, it is preferable that the second end of inflow pipeline 21 stretches to the bottom of bucket.Due to
The fluid of external pipe has a lot of impurity, after opening sampling valve 112, in order to make these impurity near sampling pipe as far as possible, is
Impurity can be discharged from sampling pipe thus be extracted by staff, and the second end of the inflow pipeline 21 in this utility model is stretched
Enter the bottom to bucket.
In the course of the work, no matter storing how many material to be sampled in storage organization 12, the fluid with impurity can arrive first always
Reach the bottom of the storage organization 12 mutually close with probe tube 111, to keep accuracy during sampling as much as possible.
In order to make storage organization 12 can try one's best many storage materials to be sampled, the second end of the flowline 22 in this utility model
It is connected to the one end at the close bucket top of bucket sidewall.During work, the material to be sampled in storage organization 12 arrives storage
Bucket top just can flow back into external pipe from flowline 22.In the case of the size constancy of storage organization 12, to greatest extent
Add the storage volume of storage organization 12.
In order to make producing well sampler of the present utility model sampling sample more accurate, it is possible to different from external pipe as far as possible
The material to be sampled contact of aspect, it is preferable that the first end of inflow pipeline 21 stretches to inside external pipe, inflow pipeline 21
The first end be provided with and meet liquid structure 211.
During work, contact with the different fluidized beds of the material to be sampled in inflow pipeline 21 by meeting liquid structure 211, thus ensure
The accuracy of sampling.
Preferably, the liquid structure 211 of meeting in this utility model is the oblique section 214 on inflow pipeline 21, this oblique section 214
The flow direction of incline direction material to be sampled with in external pipe is relative.During work, oblique section 214 is in face of in external pipe
Material to be sampled is introduced in storage organization 12.
Preferably, the inflow pipeline 21 in this utility model is provided with oil-feed control valve 212, flowline 22 is provided with out
Oil control valve 213.When storage organization 12 breaks down or needs cleaning, close oil-feed control valve 212 and go out oil control valve 213,
Storage organization 12 is repaired or changed, after completing, oil-feed control valve 212 is opened with going out oil control valve 213.In like manner,
Be sampled operation time, it is also desirable to oil-feed control valve 212 is closed with going out oil control valve 213, open again after having sampled into
Oil control valve 212 with go out oil control valve 213, the storage organization 12 in this utility model works on.
Producing well sampler of the present utility model can at any time the material to be sampled in external pipe be collected storage,
Have a rest the fuel-displaced phase, as long as the fuel-displaced producing well sampler of the present utility model of external pipe will be collected storage, thus keep away
Exempt to run into when staff samples external pipe and do not go out oil condition and the problem that cannot be carried out sampling work.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this area
For technical staff, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, institute
Any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
