Abstract
The invention relates to a portable closed sampling bucket. When the sampling is carried out on an oil well in an oilfield or the tank field of a chemical plant, in order to avoid injuring sampling operators due to the overflow of harmful gases such as hydrogen sulfide, the portable closed sampling bucket realizes closed sampling. The portable closed sampling bucket consists of a switch 1, a piston 1, a sealing ring 3, a cylinder sleeve 4, a gland 5, a pull rod 6 and a handle 7. During use of the portable closed sampling bucket, the piston 2 is pushed by a sampled liquid-gas mixture to discharge air in the cylinder sleeve through a vent hole 8 in the gland 5, so that air enters the cylinder sleeve 4, the switch 1 is turned off, and a closed cavity is formed at the moment; and then a wellhead sampling valve is switched off, the portable closed sampling bucket is separated from the wellhead sampling valve, the sampled liquid-gas mixture is closed in the portable closed sampling bucket at the moment to realize closed sampling. The hurt to sampling workers due to the overflow of harmful gases such as hydrogen sulfide is avoided.
Description
Technical field:
When the invention relates to oilfield sampling or the sampling of tank field, chemical plant, overflow to sampling operation person's injury for avoiding harmful gases such as sulfuretted hydrogen.And realize airtight sampling, especially: light airtight sample bucket.
Prior art:
The crude oil sampling that oil well is carried out in present oil field all is open hand sampling, because the oil field can produce a large amount of secondary sulfuretted hydrogen when technological measures such as enforcement steam flood, chemical flooding, cause security incident to making the workman easily cause hydrogen sulfide poisoning when the oil well that contains sulfuretted hydrogen is taken a sample.The way of taking now is the time all to be that the workman carries air respiratorresuscitator and goes operation in the well sampling that contains hydrogen sulfide gas, because the well of sampling is many and air respiratorresuscitator is quite heavy, causes working strength of workers to increase.And the workman is the sampling operation inconvenience under the situation of bearing a heavy burden, and is dangerous, cause the workman to be reluctant to wear air respiratorresuscitator when sampling, and the instrument that addresses this problem also never occurs.
Summary of the invention:
The invention purpose is: designed light airtight sample bucket, enable to solve the problem that the hydrogen sulfide containing oil well in oil field is easily caused danger when sampling.1, it is light: be easy to carry, and simple and quick, solved the oil field workman does not like to wear very heavy air respiratorresuscitator when the oil well sampling of sulfuretted hydrogen problem.2, it can realize airtight sampling: become present airtight sampling by original open sampling, hydrogen sulfide gas is placed in the airtight sample bucket can not leak outside, the problem that hydrogen sulfide gas is overflowed and hurted sb.'s feelings when having solved sampling.For achieving the above object the invention be achieved in that light airtight sample bucket by: switch, piston, O-ring seal, cylinder sleeve, gland, pull bar and handle are formed.It is characterized in that: the O-ring seal of light airtight sample bucket is enclosed within on the piston, and piston is in cylinder sleeve, and pull bar is connected in piston, and the gland that has air hole is screwed in an end of cylinder sleeve, and switch is screwed in the other end of cylinder sleeve, the handle cylinder lever connecting rod.When using the light airtight sample bucket of the invention, place the top (near a side of switch) of cylinder sleeve because the O-ring seal sealing is arranged between piston and the cylinder sleeve in piston by the handle pushing drawing rod earlier, piston is discharged the air in the cylinder sleeve, then light airtight sample bucket is connected with the wellhead sampling valve, open the switch on the light airtight sample bucket earlier, open the wellhead sampling valve again, the interior liquid vapour mixture of well this moment is being applied under the effect of pressure on the piston of light airtight sample bucket, promote descent of piston, piston is discharged the air in the cylinder sleeve by the air hole on the gland, when walking to the gland place, piston stops, this moment, the liquid vapour mixture in the well entered in the cylinder sleeve of light airtight sample bucket (if it is very little to open behind the wellhead sampling valve fluid pressure in the well, be not enough to promote piston, this moment, the available fixed handle that pulls brought to the gland place by pull bar with piston, liquid vapour mixture in the well enters in the cylinder sleeve of light airtight sample bucket under the effect of external force), close the switch of light airtight sample bucket, close the well head sample valve again, light airtight sample bucket is separated with the wellhead sampling valve, and airtight sampling is finished.
Description of drawings:
Accompanying drawing is: the semisectional view of light airtight sample bucket
Embodiment:
Below with reference to the accompanying drawings (as shown in the figure) the invention is described further: light airtight sample bucket comprises: a two ends band screw thread (or end band screw thread, one end band rapid-acting coupling) switch 1 is screwed on the cylinder sleeve 4, O-ring seal 3 is contained on the seal groove of piston 2, pull bar 6 is screwed on (or hanging over) piston 2, then piston 2 is put in the cylinder sleeve 4, the gland 5 that will have an air hole 8 is enclosed within pull bar 6 and is screwed on the cylinder sleeve 4, and handle 7 is fixed on the pull bar 6.When piston 2 at the gland of arrival bottom 5 places of cylinder sleeve 4 and when closing switch 1, form an airtight cavity this moment between O-ring seal 3 and piston 2 cylinder sleeves 4 switches 1, this cavity be exactly will sampled liquid closed chamber, when switch 1 is opened, by handle 7 pushing drawing rods 6 piston 2 is placed the top (near a side of switch) of cylinder sleeve 4 earlier, owing between piston 2 and the cylinder sleeve 4 O-ring seal 3 is arranged, air in the closed cavity is discharged from, switch 1 with light airtight sample bucket is connected with the wellhead sampling valve again, open the wellhead sampling valve, owing on the piston 2 O-ring seal 3 is arranged, and form sealing between the cylinder sleeve 4, the interior liquid vapour mixture of well this moment is being applied under the effect of pressure on the piston 2, it is descending to promote piston 2, piston 2 is discharged the air in the cylinder sleeve 4 by the air hole 8 on the gland 5, after walking to gland 5 places, piston 2 stops, this moment, the liquid vapour mixture in the well entered in the cylinder sleeve 4 (if it is very little to open behind the wellhead sampling valve liquid vapour mixture pressure in the well, be not enough to promote piston 2, this moment, the available fixed handle 7 that pulls brought to gland 5 places by pull bar 6 with piston 3, liquid vapour mixture in the well enters in the cylinder sleeve 4 under the effect of external force), close switch 1, close the well head sample valve again, light airtight sample bucket is separated with the wellhead sampling valve, sampled liquid vapour mixture is closed in the light airtight sample bucket, can not leak, finally realize airtight sampling.
Above-described only is the preferred embodiments of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some distortion and improvement, also should be considered as belonging to protection scope of the present invention.
