Abstract
The splash-proof closed sampler for oil well is used for sampling the produced liquid from oil well in oil field. Comprises a crude oil inlet pipe, a first sampling bottle, a connecting pipe, a second sampling bottle and a gas outlet pipe; a first bottle cap is fixed on the first sampling bottle, and a second bottle cap is fixed on the second sampling bottle; the two ends of the connecting pipe are respectively inserted into a first bottle cap and a second bottle cap, and the first sampling bottle is communicated with the second sampling bottle; a crude oil inlet pipe is inserted into the first bottle cap; a gas delivery pipe is inserted on the second bottle cap. The effect is as follows: because the double sampling bottles are used for sampling, the accuracy of oil sampling data of the oil well is improved, the phenomenon that the crude oil pollutes the environment in the sampling process is effectively prevented, and the defect of potential safety hazard generated in the sampling process is overcome.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of oil well produced liquid oil thief is the airtight ST of a kind of oil well protected against splashing water.
Background technology
In oil pipeline, gathering oil sample, detect the water percentage in the oil sample, is the routine work in oil recovery post.Get accurate oil sample, could accurately measure water ratio in oil well, sampling work directly influences the analysis of geologist to the underground situation of oil well.In daily sampling process, use uncovered mineral water bottle directly to take a sample, under the effect of oil well pressure, the associated gas that oil well produces often carries oil-water mixture and sputters sampling jar.Not only had influence on the accuracy but also the contaminated environment of moisture chemical examination, simultaneously, a large amount of oil gas spreads in the air; When particularly the paraffin control with inhibitor well is taken a sample; Chemical agent has certain toxicity, directly has influence on employee's physical and mental health, becomes a potential safety hazard in the safety in production.
The utility model content
The purpose of the utility model is: provide a kind of oil well protected against splashing water airtight ST, accomplish the oil well crude oil sampling, oil-water mixture sputters sampling jar, crude oil pollution on the environment phenomenon when overcoming sampling; It is big to solve the oil well moisture fluctuation of taking a sample, the inaccurate deficiency of oil sample data.
The technical scheme that the utility model adopts is: the airtight ST of oil well protected against splashing water comprises crude oil ingress pipe, first sampling jar, connecting pipe, second sampling jar and gas eduction tube.It is characterized in that: be fixed with first bottle cap on first sampling jar, be fixed with second bottle cap on second sampling jar; The two ends of connecting pipe are inserted first bottle cap and second bottle cap respectively, make between first sampling jar and second sampling jar to be communicated with; On first bottle cap, be inserted with the crude oil ingress pipe, oil sample can get in first sampling jar through the crude oil ingress pipe; On second bottle cap, be inserted with gas eduction tube, the gas in second sampling jar can be discharged through gas eduction tube.
In order to make the liquid in first sampling jar can not get into connecting pipe, there is filter screen the connecting pipe end in second sampling jar, and filter screen can stop liquid to get in the connecting pipe.
The beneficial effect of the utility model: the airtight ST of the utility model oil well protected against splashing water; Because two sampling jars are taken a sample; Improved the draw oil sample precision of data of oil well; Effectively prevent the phenomenon of crude oil pollution environment in the sampling process, overcome the deficiency of the potential safety hazard that produces in the sampling process.
Description of drawings
Fig. 1 is the airtight sampler structure diagrammatic cross-section of the utility model oil well protected against splashing water.
Among the figure, 1-first sampling jar, 2-first bottle cap, 3-crude oil ingress pipe, 4-filter screen, 5-connecting pipe, 6-second sampling jar, 7-second bottle cap, 8-gas eduction tube.
Embodiment
Embodiment 1: with an airtight ST of oil well protected against splashing water is example, and the utility model is done further explain.
Consult Fig. 1.The airtight ST of the utility model oil well protected against splashing water comprises crude oil ingress pipe 3, first sampling jar 1, connecting pipe 5, second sampling jar 6 and gas eduction tube 8.Be fixed with on first sampling jar 1 on first bottle cap, 2, the second sampling jars 6 and be fixed with second bottle cap 7.
The two ends of connecting pipe 5 are inserted first bottle cap 2 and second bottle cap 7 respectively, make between first sampling jar 1 and second sampling jar 6 to be communicated with, and what connecting pipe 5 adopted is 8 millimeters copper pipes.Be inserted with crude oil ingress pipe 3 at first bottle cap 2 on also, it is 40 centimetres plastic tube that crude oil ingress pipe 3 adopts diameters.On second bottle cap 7, also be inserted with gas eduction tube 8, gas eduction tube 8 employing diameters are 40 centimetres plastic tube.Connecting pipe 5 ends in second sampling jar 6 are surrounded by three metafiltration nets 4.
At the many mouthfuls of airtight STs of the aboveground oil well protected against splashing water on probation of thin oil, the qualification rate of oil sample is increased to 90% by 70%, and is free from environmental pollution.Security also is further enhanced.
Claims (2)
1. the airtight ST of oil well protected against splashing water comprises crude oil ingress pipe (3), first sampling jar (1), connecting pipe (5), second sampling jar (6) and gas eduction tube (8); It is characterized in that: be fixed with first bottle cap (2) on first sampling jar (1), be fixed with second bottle cap (7) on second sampling jar (6); The two ends of connecting pipe (5) are inserted first bottle cap (2) and second bottle cap (7) respectively, are communicated with between first sampling jar (1) and second sampling jar (6); On first bottle cap (2), be inserted with crude oil ingress pipe (3); On second bottle cap (7), be inserted with gas eduction tube (8).
2. the airtight ST of oil well protected against splashing water according to claim 1 is characterized in that: there is filter screen (4) connecting pipe (5) end in first sampling jar (1).
