Abstract
Description
Technical field
The utility model relates to a kind of rock adsorbed gas content proving installation, particularly relates to a kind of visualized air content tester.
Background technology
The ADSORPTION STATE rock gas is prevalent in rock and other preserve in the medium, and for shale gas and coal-seam gas, the air content test is indispensable, and the shale air content can reach 20%-80%, and coal-bed gas content is more up to 80%-99%; For other mines of possibility gassiness, the formation gas bearing amount also can reach more than 20%.No matter be as the useful rock gas of exploiting purpose, still, apparent important to the research and the test day of these adsorbed gas as " being harmful to " rock gas of prevention forecast.
The rock gas desorption experiment is the experiment that is used for testing adsorbed gas content in the gas-bearing reservoir sample.Though rock gas adsorbed gas content test experiments is widely used in the natural gas exploration and development process; But owing to cost an arm and a leg, effects limit such as the directly perceived and measuring accuracy of complicated operating process, desorption process, present air content test can not satisfy still that reality is produced and the demand of teaching and scientific research.
The applicant discloses a kind of adsorbed gas content measuring instrument and experimental technique thereof in No. 201010137275.1 Chinese patents of application on April 1st, 2010; This measuring instrument comprises sealable tank, gas collection graduated cylinder and experimental box; Sealable tank is provided with valve port; The air hole switch valve that the gas collection graduated cylinder is provided with the osculum variable valve and matees with valve port mainly contains heating element and temperature controller in the experimental box.During measurement; In sealable tank, pack into earlier gassiness sample and saturated brine and sealing, dress water and heating in experimental box is put into the experimental box water-bath with sealable tank; The saturated brine of in the gas collection graduated cylinder, packing into; Connected set tolerance tube and sealable tank are also opened the osculum of gas collection graduated cylinder, the liquid level position in the record set tolerance tube, and experiment finishes to break off and is communicated with.This patent equipment compact conformation, volume is little, impermeability good, measurement is accurate, be convenient to move and carry, be fit to that field condition uses, homogeneous heating; And experimental technique is easy to operate simple, can be specifically designed to all gases especially collection and the measurement of small size gas.
But above-mentioned existing adsorbed gas content testing apparatus still exists certain defective and improvements at different aspect, mainly shows as:
1, the device measuring precision is still waited to improve, particularly when the less time error of air content serious, promptly behind stripping gas (principal ingredient is a methane) entering test macro; The desorb space is big because gas desorption quantity is few; Make desorption quantity and gas componant be difficult to accurate mensuration, the equipment that has is owing to have than long duct, and the original air of stripping gas and internal system mixes; When collecting stripping gas; Being easy to cause stripping gas to remain in the system, when gas desorption quantity is small, is zero through the methane composition in the desorption gas of this systematic collection probably at last particularly;
2, equipment volume is bigger, and less stable involves great expense, and operability is not strong in the test at the scene;
3, when testing quantity more simultaneously, be not easy to a plurality of tests and carry out simultaneously, repeated sampling, revision test realize difficulty;
4, the separating cucurbitula and be connected valve port and be opaque material of instrument, so the desorb that in jar, takes place of sample changes and the situation of giving vent to anger can't observe directly.
This shows; Above-mentioned existing adsorbed gas content measuring equipment still has demands improvements urgently; How to found that a kind of measuring accuracy is higher, volume is littler, structure is simpler and the visualized air content tester of the new structure that desorption process is directly perceived, visual, is one of improvement target of current industry.
The utility model content
The technical matters that the utility model will solve provides a kind of visualized air content tester, makes that its measuring accuracy is higher, volume is littler, structure is simpler and desorption process is directly perceived, visual.
For solving the problems of the technologies described above; A kind of visualized air content tester of the utility model comprises that core separates cucurbitula and gas collection graduated cylinder, and wherein: rock core is separated cucurbitula; Comprise top cover that is tightly connected and the transparent tank body that adopts the tempered glass material, and on top cover, be provided with vent port; The gas collection graduated cylinder comprises the transparent cylindrical shell that indicates scale and is provided with air hole and the tube end of osculum; The air hole of gas collection graduated cylinder is communicated with the vent port sealing that rock core is separated cucurbitula.
As a kind of improvement of the utility model, the osculum of described gas collection graduated cylinder is a draining aperture, and on the draining aperture, is provided with switch valve.
The aperture of described draining aperture is 0.5mm-4.5mm.
The aperture of described draining aperture is 2.5mm.
The box and pin sealing of air hole through quick junction button that described rock core is separated vent port and the gas collection graduated cylinder of cucurbitula is communicated with.
The cylindrical shell of described gas collection graduated cylinder was connected through thread seal with the tube end.
The internal diameter that described rock core is separated cucurbitula is 75mm, high 300mm.
The range of capacity of described gas collection graduated cylinder is 0～600ml, and minimum scale is 5ml.
After adopting such structure, the utility model has the following advantages at least:
1, the experiment overall process realizes transparence, has reached observing effect intuitively, and self-checking capability is strong, is convenient to reduce experimental error and improves analysis precision;
2, project organization is optimized, reduced production and manufacturing cost, for producing in batches and wide popularization and application is laid a good foundation;
3, of many uses, can be applied to on-the-spot and indoor production test, the theoretical research in the laboratory and teaching simultaneously and show;
4, volume is littler, is easy to carry, and is suitable for batch testing, intensive sampling test and contrast test under the different condition, is particularly suitable for the high precision measurement of small air content;
5, except methane gas, also applicable to the site desorption and the air content analysis of multiple other types rock gases such as coal-seam gas, chalk gas, compact sandstone gas, hydrate;
6, except that rock gas research, in other field, also can have a wide range of applications, mainly comprise mine safety, methane explosion prevention, environmental monitoring, ecological Studies and food security etc.;
7, it is that first is used for test of rock core adsorbed gas content and omnidistance transparent visual professional measuring equipment at present.
