Abstract
A kind of high tolerance Samper for oil well, including：Oil inlet pipe（0）, elbow（1）, central tube（2）, housing（3）, flowline（4）；It is characterized in that：The oil inlet pipe（0）, elbow（1）, central tube（2）It is welded as a whole successively, central tube（2）Insert housing（3）Centre and sealed attachment, housing（3）Lower end be provided with flowline（4）.The utility model is applied to the oil well oil sample admission work of the high tolerance in oil field, reduces well water Error and Assay, enrolls correct aqueous data, is easy to examine oil well output and oil well analysis, this is significant for oil field development.
Description
Technical field
The sub-sampling utensil of the high tolerance oil well in oil field is the utility model is related to, belongs to wellhead hardware, specifically one
The high tolerance Samper for oil well of kind.
Background technology
The aqueous chemical examination data of rod-pumped well is the primary data of oil well, and its aqueous data is to calculate the weight of oil well output
Want index.But the air content of some oil wells is larger, a large amount of natural gases therein can be impacted in sample cylinder during sampling liquid makes splash
The crude oil risen sprays sample bucket, influences the degree of accuracy of aqueous data, and worker is afraid of that crude oil sprays during sampling, and by sampling gate open compared with
Small, this will cause the oil sample water heavy wool of acquirement few, cause the aqueous higher of oil well, influence crude output.
The content of the invention
The purpose of this utility model reduces gas aiming at drawbacks described above existing for prior art, during in order to draw oil sample
Influence, improve the degree of accuracy of well water laboratory values, devise a kind of high tolerance Samper for oil well.
The utility model is realized by following technical proposals：
The utility model includes：Oil inlet pipe, elbow, central tube, housing, flowline；It is characterized in that：It is the oil inlet pipe, curved
Head, central tube are welded as a whole successively, and the centre of central tube insertion housing and sealed attachment, the lower end of housing is provided with fuel-displaced
Pipe.
Oil inlet pipe in a kind of above-mentioned high tolerance Samper for oil well is provided with external screw thread.
Central tube in a kind of above-mentioned high tolerance Samper for oil well, which is located at enclosure interior and point is laid with 3~5mm of Φ, to be gone out
Stomata.
Diameter of the housing in a kind of above-mentioned high tolerance Samper for oil well is more than twice of central tube, and bottom is provided with buffering
Plate, buffer board are provided with four Φ 8~12mm flowing holes, and enclosure interior is divided into top air storing cavity and lower buffer chamber by buffer board.
The diameter of flowline in a kind of above-mentioned high tolerance Samper for oil well is identical with center pipe diameter.
Operation principle：Sample cock is opened, oil gas water mixed liquid enters housing Inner by oil inlet pipe, elbow, central tube,
Gas in oil gas water mixed liquid enters air storing cavity by venthole, alleviates oil gas water mixed liquid largely injection pressure, liquid
Being fallen under body on buffer board, gas separates again, and oil-water mixture enters cushion chamber by flowing hole under gravity,
Sample bucket is entered by flowline.
The beneficial effects of the utility model are：Work is enrolled suitable for the oil well oil sample of the high tolerance in oil field, oil well is reduced and contains
Water Error and Assay, correct aqueous data is enrolled, be easy to examine oil well output and oil well analysis, this has important for oil field development
Meaning.
Brief description of the drawings
Fig. 1-the utility model scene main view complete section structural representation
In figure, 0. oil inlet pipe, 1. elbows, 2. central tubes, 3. housings, 3-1. buffer boards, 4. flowlines；Q. venthole, C.
