Abstract
The pressure maintaining sealed tank for coal rock and shale samples is applied to the gas content test of coal beds and shales. The tank body is a circular metal cylinder, and one end of the tank body is provided with a bottom; the other end of the tank body is provided with external threads, the other end of the tank body is in threaded connection with a tank top cover, a cylindrical connector which protrudes outwards is arranged in the center of the tank top cover, the cylindrical connector is provided with a central hole, the central hole of the cylindrical connector is provided with internal threads, and a quick connector is in threaded connection with the cylindrical connector; a regular hexagonal body is fixed at the center of the outer side of the bottom of the tank body. A rubber O-shaped sealing ring is arranged between the tank body and the tank top cover. The effect is as follows: the quick connecting buckle is adopted to be connected with other experimental instruments, the operation is simple and quick, the connection can be disconnected at any time, the sealing time after sample loading is short, and the gas escape is avoided, so that the gas quantity measurement precision is improved; the utility model discloses the gas tightness is better, can remove wantonly during the use, overturn, is suitable for extensive popularization.
Description
Technical field
The utility model relates to the coal seam, the shale reservoir gas-bearing measures examination assessment technique field, particularly relates to a kind of gassiness coal petrography and shale sample pressurize jar, is a kind of special-purpose pressurize vapor tight tank that stores the shale sample.
Background technology
Coal-seam gas, shale gas are to compose to deposit a kind of in coal seam or the shale and be absorption, dissociate or the rock 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 gas reservoir 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 rock gas, particularly concerning unconventional rock gases such as coal-seam 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 rock gas adsorbed gas and free gas content is a important process in the non-conventional gas exploratory development in the gassiness sample.
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 vapor tight tank of gassiness coal petrography and shale sample need being packed into, vapor tight tank is placed in the water bath of constant temperature.The coal petrography or the shale that are placed in the sealable tank begin to carry out the nature desorb, by wireway, plastic lined piping and a sealable tank internal communication that terminates on the vapor tight tank, 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.Use through on-the-spot, find that there is following defective in above-mentioned experimental system:
1, sealable tank is undersized, is not suitable for coal-seam gas, shale gas well institute cut-off and directly is the 68mm rock core, need will reinstall in the tank body after coal petrography and the shale pulverizing, and gas scattered and disappeared in a large number after sample was ground into particle, caused test inaccurate;
2, after sample is packed into, the bottom outside lacks the hexa-prism boss, and spanner or hand vice clamping difficulty cause top cover airtight not tight, and gas leaks, and measures inaccurate.
The utility model content
The purpose of this utility model is: a kind of coal petrography and shale sample pressurize sealable tank are provided, be used to collect the gassiness sample, coal petrography and shale sample are deposited in sealing, and impermeability is better, easy to use, dress can be tightened behind the sample airtight rapidly, improves test accurately, overcome existing sealable tank gas and leak, measure inaccurate deficiency.
The technical solution adopted in the utility model is: coal petrography and shale sample pressurize sealable tank comprise tank body, top ends of cans, rapid-acting coupling, O-ring seal and positive hexahedron.Tank body is the circular metal tube, and tank body one end has the end; It is characterized in that: the tank body other end has external thread, the tank body other end top ends of cans that is threaded, at the right cylinder connector of the oriented outer lug in the center of top ends of cans, the right cylinder connector has center pit, right cylinder connector center pit has internal thread, and rapid-acting coupling has been threaded on the right cylinder connector.Be fixed with positive hexahedron in the tank base outer side center.Positive hexahedron is convenient to spanner or hand vice clamping.
In order to improve sealing, the RUBBER O RunddichtringO is arranged between tank body and top ends of cans.
Tank body and top ends of cans adopt stainless steel or aluminium to make.
The beneficial effects of the utility model: the utility model coal petrography and shale sample pressurize sealable tank, adopt quick junction button to be connected with other experimental apparatuss, good airproof performance, simple to operate, rapid, at any time can utilize rapid-acting coupling disconnection or associated line, the dress sample operation time is short, has avoided the loss of gas, thereby has improved the tolerance measuring accuracy; Can move arbitrarily during use, overturn.
Description of drawings
Fig. 1 is the utility model coal petrography and shale sample pressurize sealable tank structural profile synoptic diagram.
Among the figure, 1-tank body, 2-top ends of cans, 3-rapid-acting coupling, 4-O-ring seal, the positive hexahedron of 5-.
Embodiment
Embodiment 1: with a coal petrography and shale sample pressurize sealable tank is example, and the utility model is described in further detail.
Consult Fig. 1, the utility model coal petrography and shale sample pressurize sealable tank, coal petrography and shale sample pressurize sealable tank comprise tank body 1, top ends of cans 2, rapid-acting coupling 3, O-ring seal 4 and positive hexahedron 5.Tank body 1 is circular stainless steel cylinder, and tank body 1 one ends have the end.Tank body 1 other end has external thread, tank body 1 other end top ends of cans 2 that is threaded, and top ends of cans 2 adopts stainless steels to make.At the right cylinder connector of the oriented outer lug in the center of top ends of cans 2, the right cylinder connector has center pit, and right cylinder connector center pit has internal thread, an end of the rapid-acting coupling 3 that is threaded on the right cylinder connector.Be welded with a positive hexahedron 5 at tank body 1 bottom outside center.Between tank body 1 and top ends of cans 2, RUBBER O RunddichtringO 4 is arranged.
During experiment, coal petrography and shale sample pressurize sealable tank are positioned in the thermostatic box, top ends of cans 2 up, and the buret that will have scale docks with rapid-acting coupling 3 of the present utility model by pipeline, pipeline connects gas collecting device, thereby is measured the air content of coal seam in coal petrography and the shale sample pressurize sealable tank or shale.
