Abstract
The splash-proof well head sampler is used in oil extraction well head sample collection in oil field. Is characterized in that: the sampling tube is sleeved with a three-way sleeve, the three-way sleeve is welded with the tube joint, the outer wall of the three-way sleeve is welded with an annular baffle, the outer wall of the three-way sleeve is sleeved with a conical rubber sealing cover, and the conical rubber sealing cover is arranged at the lower part of the annular baffle. The conical rubber sealing cover is covered on the bottle mouth of the sampling bottle. The effect is as follows: can prevent the pollution caused by the fact that crude oil is splashed out of the sampling bottle in the sampling process of the oil well. The natural gas that can produce in the sampling process draws out the sampling bottle and arranges outdoor side by side, has improved operational environment, reduces the injury of natural gas to the person, prevents to cause the emergence of catching fire, the explosion accident that the natural gas gathering produced in the insulation can because of the sample.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of special tool of producing well well head sampling is a kind of antispray well mouth of oil well sampler.
Background technology
For oil well produced liquid is chemically examined, carry out timing sampling to well mouth of oil well extraction liquid.Timing sampling is oil recovery worker's routine work, also is that the oil recovery worker feels the work of " headache ".
At present, oil well wellhead sampling device is mainly simple and easy sampler on the oil field, and its structure is made up of a sampling bottle, union and a probe tube (thin copper pipe), and union and probe tube weld together.This kind sampler mostly is respectively that the unit of oil recovery processes voluntarily, and is simple in structure, because the simple and easy sampler structure of this kind is simple, easy to process, thereby uses in a large number on the oil field.Also has the wellhead sampling device of antifreeze function at cold district, the oil well of being announced as the Chinese patent ZL 200520018471.1 wellhead sampling device that sampler, ZL93216227.4 are announced winter, the antifreeze sampler of production wellhead that the patent No. 87216480.2 is announced.These three kinds of samplers all are to be made of the sample cock with antifreeze function and a sampling pipe nipple.
The problem that at present known well mouth of oil well sampler exists is: the outlet of sampler all is to be made of the sampling pipe nipple, does not have the sampling bottle sealing means of bottleneck, does not possess the antispray function.In the sampling process, oil gas impacts the crude oil in the sampling bottle and produces splash, and the natural gas of separating in the crude oil can carry the crude oil ejection sampling bottle that splash rises.Perhaps when oil well is taken a sample,, make oil sample overflow sampling bottle and pollute when the sampler flow increases suddenly and has little time to close sample cock.And existing sampler all is installed in the oil well incubator mostly, the natural gas of separating in the crude oil during sampling can spray from the bottleneck of sampling bottle and accumulate in the incubator, because incubator is a space of sealing, natural gas is not easy diffusion, the potential safety hazard of just exist blast when natural gas is accumulated to certain concentration, catch fire, personnel poisoning.In the winter of northern area, the staff will enter the interior sampling of incubator of flowing well, and natural gas that sprays during sampling and mist of oil spread in the interior certain threat of healthy and safe formation to the staff of incubator.Existing oil well sampler structure is unreasonable, can produce splash during sampling, and particularly when the big oil well of gas production was taken a sample, the splash phenomenon was particularly serious.
The utility model content
The purpose of this utility model is: a kind of antispray wellhead sampling device is provided, and the natural gas of ejection is drawn incubator during with sampling, eliminates safe hidden trouble.Overcome existing well mouth of oil well sampler and can not prevent the crude oil splash, can cause the pollution problems of equipment and environment.
The technical solution adopted in the utility model is: antispray wellhead sampling device, mainly to form by union, probe tube, ring baffle, cone rubber seal cover, threeway sleeve pipe and sampling bottle, and union and probe tube weld together.It is characterized in that: be with a threeway sleeve pipe in the outside of probe tube, threeway sleeve pipe and union weld together, and the threeway sleeve pipe is parallel with probe tube, between threeway sleeve pipe and the probe tube annular space is arranged.Probe tube is than 5～45 millimeters of threeway cover pipe ranges.Be welded with ring baffle on the outer wall of threeway sleeve pipe, be with a cone rubber seal cover on the outer wall of threeway sleeve pipe, the cone rubber seal cover is in the bottom of ring baffle.The cone rubber seal cover covers on the bottleneck of sampling bottle.During sampling, union top is connected with the sampling control valve, opens the sampling control valve, and the extraction liquid that contains natural gas enters from the union centre bore, by probe tube, enters in the probe tube, and the natural gas in the extraction liquid is separated.Natural gas is overflowed through annular space is arranged between threeway sleeve pipe and the probe tube, from the gas outlet outflow of threeway sleeve pipe; Crude oil is stayed in the sampling bottle.Natural gas has had a passage, can not cause extraction liquid sample splash phenomenon.
For the natural conductance that flows out from the gas outlet of threeway sleeve pipe is walked, on the gas outlet of threeway sleeve pipe, be connected with the air guide sebific duct.
The minimum angle of the center line of the outlet section of probe tube and probe tube center line is between 30～60 degree.
The beneficial effects of the utility model: the antispray wellhead sampling device of the utility model, the sampling bottleneck is sealed, can prevent from that the crude oil splash goes out sampling bottle in the oil well sampling process to pollute.The natural gas that produces in the sampling process can be drawn sampling bottle, and enter in the blowdown bucket, improve working environment, reduce the injury of natural gas, prevent generation because of sampling catching fire of causing that gas accumulation produces in incubator, explosion accident to the person.
