Description
Technical field
The utility model relates to the coal seam, the shale reservoir gas-bearing measures examination assessment technique field, particularly relates to the experimental facilities of air content tests such as a kind of shale, coal bed gas, a kind of nested knockdown hermetically sealed can.
Background technology
Coal bed gas, shale gas are to compose to deposit a kind of in coal seam or the shale and be absorption, dissociate or the natural gas of dissolved state.In the conventional gas reservoir, generally be mainly free gas and solution gas, substantially there is not adsorbed gas, and in unconventional natural gas reservoirs such as coal seam and shale, adsorbed gas content is higher, adsorbed gas and free gas content are generally greater than 90% in coal seam and the shale, the size of absorption and free gas absorption air content is directly connected to the enrichment degree and the development technique of natural gas, particularly concerning unconventional natural gases such as coal bed gas, shale gas, adsorbed gas and free gas assay are the key factors of evaluating reservoir, reserve estimate and development and Design.Therefore, the test experiments of natural gas adsorbed gas and free gas content in the gassiness sample has been widely used in shale gas, the cbm exploration exploitation.In addition, in fields such as mining and gas detection, environmental protection and monitoring, also be widely used.
At present, also be not used in the special-purpose experimental facilities that adsorbed gas and free content are accurately measured.When utilizing Routine Test Lab equipment to carry out the experiment of adsorbed gas and free gas content measuring, the single isolated hermetically sealed can of gassiness coal petrography and shale sample need being packed into, hermetically sealed can is placed in the water bath of constant temperature.The coal petrography or the shale that are placed in the hermetically sealed can begin to carry out the nature desorb, by wireway, plastic lined piping and a hermetically sealed can internal communication that terminates on the hermetically sealed can, the other end stretches into U type buret upper opening, be placed with in the buret and dye coloured liquid, by U type connecting pipe principle the amount of gas is carried out reading and measure.The experimental system of utilizing above-mentioned laboratory conventional equipment to assemble can satisfy the requirement of desorb reaction, collection and the assay of coal bed gas, shale gas substantially, and still, we find in actual use, and there is following defective in above-mentioned hermetically sealed can when experiment:
Because the hermetically sealed can tank diameter that adopts in the above-mentioned experiment is fixed, when the rock core at different-diameter uses, when putting into the rock core of minor diameter, because there are the space in rock core and tank diameter, air in the space can't be got rid of and cause in the sealed tank body in the gas of detection and is mixed with a large amount of air, causes the result inaccurate.
The tank body valve port is the employing rubber seal generally, utilizes medical needle to adopt the mode of acupuncture to carry out gas and connects, and rubber pad needs to change once more in case the puncture back just can not be reused once more, and is very inconvenient.
3, in experiment, if there is the light density gas of trace to be positioned at the top of hermetically sealed can in the hermetically sealed can, when using the needle pierces sealing mat to gather the gas sample, the length that syringe needle inserts can not accurately be controlled, the part that needle tip enters hermetically sealed can might occur and just in time be under the gas, can't gather gas.
This shows that above-mentioned existing hermetically sealed can experimental facilities obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.
The utility model content
The purpose of this utility model is: a kind of nested type combination sealing jar is provided, is exclusively used in collection, sealing and the gas sample acquisition of shale, coal petrography gassiness sample, the air in can remover apparatus behind the dress sample is tested more accurately, and tightness is good.
The technical solution adopted in the utility model is: nested type combination sealing jar comprises tank body, jar mouthful outer, bolt, middle cover, interior cover, top cover, wing nut, snap joint and O RunddichtringO.Tank body is the circular metal tube, and tank body one end has the end; It is characterized in that: tank body other end outer wall is welded with a jar mouthful outer, and the last plane vertical welding of jar mouthful outer is connected to bolt, and bolt evenly distributes; In tank body, have in the cylindrical shape and overlap, in middle cover, have in the cylindrical shape and overlap; Top cover is arranged at the top at tank body, at the edge of top cover bolt hole is arranged, and bolt hole is relative with jar bolt of mouthful outer, and bolt passing through bolt hole is fixed with wing nut on bolt; Lower plane at top cover has the protruding ring body, and the external diameter of annular solid is identical with the tank body internal diameter, is with the O RunddichtringO on the outer wall of annular solid; The cylinder connector of the oriented outer lug in center on plane on top cover, the cylinder connector has centre bore, and cylinder connector centre bore has internal thread, and snap joint has been threaded on the cylinder connector.
Tank body, middle cover, interior cover and top cover adopt stainless steel or aluminium to make.
The cover external diameter is identical with the tank body internal diameter in described; Interior cover external diameter is identical with middle cover internal diameter.Middle cover in tank body and interior cover can be according to the big freedom in minor affairs assemblings of laboratory sample specification.
The beneficial effects of the utility model: the utility model nested type combination sealing jar is exclusively used in collection, sealing and the gas sample acquisition of gassiness rock samples such as coal petrography, shale; The top adopts snap joint external, and tightness is good, and is easy to connect, reduced the gas loss, can be at any time and external connection, and gas in can collecting tank; Be convenient to the collection of small volumes of gas; Can be fit to the different-diameter rock core, the air in the ring-type cylinder emptying tank body make experimental result more accurate, and mobility is strong.
