Description
Technical field
The utility model relates to a kind of heating desorption tank, is be the device carrying out content measurement in the main unconventional oil and gas resource exploration such as coal-seam gas, shale gas for adsorbed gas.Under can ensureing that the desorption process of adsorbed gas in coal-seam gas, shale gas is in design temperature condition by this device, ensureing that desorb stablized by sample, providing condition for accurately calculating its stripping gas content, reserves calculating etc.Belong to unconventionaloil pool experimental technique field.
Background technology
Coal-seam gas, shale gas, as novel natural gas source, are just being subject to increasing attention at home.Coal-seam gas, shale gas are all that main tax deposits mode with ADSORPTION STATE, after pressure is released, and gas progressively desorb from reservoir medium.Stripping gas content is the important component part in air content, is one of the most basic in exploratory development, most important parameter.By what method undertaken measuring and all will first shale samples be carried out sealing and under remaining on uniform temperature condition
The solution cucurbitula used in current stripping gas content measuring process and heating arrangement more, widely used is heating water bath solution cucurbitula and electrical heating solution cucurbitula.But by the impact of field condition, two kinds of desorb pots carry comparatively heavy, affect field trial; There is the problems such as firing rate is slow, temperature is unstable in these two kinds solution cucurbitulas simultaneously, makes desorption process stable not, affect adsorption law, in the calculating of losing gas and air content, easily produce error.
Utility model content
The purpose of this utility model is to provide a kind of heating desorption tank, to solve under existing experiment condition desorption temperature in desorption process unstable, carry the problems such as inconvenient, by the utility model be conducive to realizing stripping gas stable detection, obtain desorption time curve, there is provided parameter for loss gas calculates, improve stripping gas accuracy of measurement, simultaneously for studying coal-seam gas further, shale gas formation mechenism provides condition.
The purpose of this utility model realizes in the following manner, a kind of heating desorption tank, comprise tank body, the cover connected through securing member and the O-ring seal of junction, the centre of cover has gas outlet, it is characterized in that, described tank body is followed successively by inner core, heating collar, heat-insulation layer and urceolus from inside to outside; The tank body at the heat-insulation layer outside heating collar and urceolus place arranges interface, inner core arranged outside temperature sensor, the signal connecting interface of temperature sensor.
Described Inner cylinder and urceolus adopt aluminum alloy materials.
Described heating collar adopts silicon rubber heating collar.
Described heat-insulation layer adopts magnesium oxide powder.
Described cover adopts aluminum alloy materials, and its inner top surface is globoidal structure.
Described tank body urceolus arranges be integrated with it three move close to somebody's ear, cover and respectively move close to somebody's ear through screw nut fastening.
Sample heating, temperature monitoring, temperature maintenance etc. are integrated by the utility model, under the support of peripheral control unit, while ensureing temperature stabilization, can reduce the impact of environment temperature, using electricity wisely.The temperature of separating in cucurbitula is controlled by controller, in experimentation, carry out temperature setting to the corresponding solution cucurbitula on controller, can carry out voluntarily heating, the operation such as constant temperature.Be conducive to realizing the stable detection of stripping gas, obtain desorption time curve, provide parameter for loss gas calculates, improve stripping gas accuracy of measurement, simultaneously for studying coal-seam gas further, shale gas formation mechenism provides effective experimental apparatus.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure, 1 cover, 2 gas outlets, 3 nuts, 4 screws, 5 O-ring seals, 6 move close to somebody's ear, 7 urceolus, 8 heat-insulation layers, 9 heating collars, 10 Inner cylinders, 11 temperature sensors, 12 interfaces.
Embodiment
Further illustrate the utility model with example by reference to the accompanying drawings, as shown in Figure 1, the utility model is primarily of cover 1, tank body composition.Tank body is by provide support and the Inner cylinder 10 of structural stability, urceolus 7 and the heating collar 9 with heat effect, the heat-insulation layer 8 with thermostatic effect form, heating collar 9 and heat-insulation layer 8 are successively set on the outside of Inner cylinder 10, the urceolus 7 upper oral part arranged outside of tank body moves close to somebody's ear 6, maintain the stability of structure, moving close to somebody's ear 6 tops has three fixed screws 4, ensures the tightness with cover 1; Cover 1 central authorities set out gas port 2, are sealed by three screws 4 and tank body, and cover 1 arranges O-ring seal 5, the impermeability of assurance device with the junction of tank body; The tank body at the heat-insulation layer 8 outside heating collar 9 and urceolus 7 place arranges interface 12, inner core 10 arranged outside temperature sensor 11, the signal connecting interface 12 of temperature sensor 11.Controller is connected with temperature sensor 11, heating collar 9 by interface 12, the stability of control device temperature.
In experimentation, after in the Inner cylinder 10 sample being loaded tank body, use screw 4 and nut 3 to seal, then connected the controller of peripheral hardware by interface 12, set corresponding solution cucurbitula temperature by controller.
The utility model incorporates separates cucurbitula and heating arrangement, and what reduce field experiment carries difficulty, ensure that the temperature stability in experimentation simultaneously, has good using value.
