Technical field
The utility model relates to the cbm development technical field, particularly relates to coal bed gas, shale gas air content testing equipment, a kind of various product experimental box that is used for coal bed gas, the test of shale gas air content.
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 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 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 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, lack portable, special-purpose experimental box and experiment porch, buret is broken easily, and warming-in-water is slow, and stability is bad;
2, because vapor tight tank does not make up well, be not easy to a plurality of vapor tight tanks tests and carry out simultaneously;
3, owing to the near-bottom temperature that water-bath need be set to the sample place when testing, and existing water-bath experimental system can't accurate, stable control reach corresponding experimental temperature.
The utility model content
The purpose of this utility model is: provide a kind of coal seam, shale air content to test various product experimental box, both held the stainless steel vapor tight tank, can be used for vapor tight tank evenly heating and insulation again, be convenient to simultaneously move and carry, be fit to field condition and use.
The technical solution adopted in the utility model is: coal seam, shale air content are tested various product experimental box, comprise casing, lid, top board, temperature controller, power interface, base plate and heating element.Casing and lid are cuboid, and lid is relative with casing and be hinged by folding, form a cuboid case.Casing and lid adopt polyvinyl (PVC) plate of material to make.It is characterized in that: top board and base plate are arranged in casing, and top board is parallel with base plate, and top board has a jar putting hole.Base plate is fixed in the casing.When the jar putting hole insertion of vapor tight tank from top board, the lower end of vapor tight tank is on base plate, and vapor tight tank can be erected in the casing.Between the top heating element is being arranged at the bottom of the bottom of base plate and the casing, lead is connected between heating element and the temperature controller, has lead to be connected between temperature controller and the power interface, and temperature controller and power interface are fixed on the top board.
Between top board and base plate, be filled with heat insulating material.
Power interface can be by lead and city 220V, and the alternating current of 50-60Hz links to each other.
On the inwall of casing, heating element can also be arranged.
Described temperature controller is digital adjustable temperature controller, and control range is at 0～100 ℃.
The long 600mm of described cabinet exterior, wide 550mm, high 500mm, the long 600mm of lid outer wall, wide 550mm, high 100mm.
The beneficial effects of the utility model: the utility model coal seam, shale air content are tested various product experimental box, have both held the stainless steel vapor tight tank, can be used for again vapor tight tank evenly, Fast Heating and insulation, be convenient to simultaneously move and carry, be fit to field condition and use.
