Description
Technical field
The present invention relates to a kind of device and method of measuring adsorbed gas coefficient of diffusion in danks.Belong to gas development technique field in danks.
Background technology
Coal-seam gas (or shale gas), refer to compose exist in coal (page) rock take methane as principal ingredient, take be adsorbed on the matrix granule surface as main, partly be free in hole or be dissolved in the hydrocarbon gas in the water of rock stratum.
Coal-seam gas (or shale gas) has following characteristics: 1., substantially not containing the heavy hydrocarbon more than C2, there is no inorganic impurity during output; If 2., in Main Underground is present in danks with the adsorbed state of macromolecular mass, possess production capacity basis preferably; 3. coal-bed gas exploitation is to reduce reservoir pressure by draining, makes coal-seam gas desorb-diffusion in the coal seam-extraction of flowing, and conventional gas is the pressure output by self; 4. the coal-seam gas initial production yields poorly, but the cycle is long, can reach many decades, and the rock gas initial potential is high, and the production cycle often is less than 10 years; 4. coal-seam gas claims again coal-mine gas, is the chief threat of coal mine production safety, and the greenhouse effect of its generation simultaneously are than CO
2by force.
Therefore, exploiting coal bed methane is conducive to: at first, reduce mine safety accidents; Secondly, can play environmental protection effect; Again, can produce good economic benefit.
Before coal-seam gas (or shale gas) is exploited, need to first see clearly its migration rule in danks, diffusion is the link that must experience in the coal bed gas product process.The output of coal-seam gas certainly will be through the process of desorb-diffusion-seepage flow, and the height of methane output is subject to the co-controlling of these three links.After reservoir pressure drops to critical desorption pressures, coal-seam gas just desorbs from the coal internal pore surface.Because microporosity that diameter is less than 10nm be take as main in the matrix of coal mesoporosity, permeability is extremely low, and at first coal-seam gas is diffused into could the seepage flow output in perviousness crack or hugger.Gas is deferred to Darcy's law seepage flow after entering the perviousness crack, and gas yield is the function of pressure and permeability.As can be seen here, diffusion plays important linking effect in the desorb output process of coal-seam gas.The motion that the essence of diffusion is gas from macromolecule density region (matrix of coal) to low molecular density district (perviousness crack), rate of propagation and gas molecule diffusion length are the inverse ratio that square is of fracture spacing.The early yield of diffusion major effect coal bed gas well and the stable production period in later stage thereof.
