Description
Technical field
The utility model belongs to petroleum gas, CBM exploration and development field, particularly a kind of shale gas gauging instrument.
Background technology
Shale gas gauge is for shale gas, cbm exploration scene, measure shale gas and coal-seam gas adsorbance, in shale gas exploratory development process, shale gas content is that shale evaluating reservoir, reserves calculate, the key parameter of development plan design, needs a kind of special shale gas gauge; Existing gauge test speed is slow, it is large-minded to lose, accuracy of detection is low, carry inconvenience, the frangible lamp shortcoming of glass cylinder.
Utility model content
In order to solve the defect of existence of above-mentioned gauge, the utility model provides a kind of shale gas gas content.
The utility model comprises aqua storage tank, gas collection measuring cylinder, between described aqua storage tank and described gas collection measuring cylinder, suction hose is set, one end of described suction hose is arranged under the liquid level of described aqua storage tank, the other end of described suction hose is arranged on the cylinder end of the interior and close described gas collection measuring cylinder of described gas collection measuring cylinder, described gas collection measuring cylinder is provided with end cover, above described gas collection measuring cylinder, weighing device is set, described gas collection measuring cylinder is lifted on described weighing device, a tracheae is tightly connected on described end cover, described tracheae is communicated with described gas collection measuring cylinder inner chamber, on described tracheae, connect shale gas air intake branch, suction branch, on described shale gas air intake branch, air inlet electromagnetic valve is set, the solenoid valve of bleeding is set on described suction branch, free end at suction branch connects self-priming pump.
The utility model also comprises resolves sample storage tank, and described parsing sample storage tank is connected to the inlet end of described air inlet electromagnetic valve by connecting pipe, and the gas outlet of described parsing sample storage tank connects hand valve.
When the utility model uses, first close air inlet electromagnetic valve, open the solenoid valve of bleeding, self-priming pump is air-breathing, make to form negative pressure in gas collection measuring cylinder, by suction hose by the salt solution inspiration gas collection measuring cylinder in aqua storage tank, when being drawn onto after a certain amount of salt solution, close the solenoid valve of bleeding, close self-priming pump, record the now reading of weighing device, the reading of weighing device can be calculated brine volume by cubature formula; The inlet end of air inlet electromagnetic valve connects shale gas storage tank by pipeline, air inlet electromagnetic valve is opened, shale gas enters gas collection measuring cylinder, shale gas is discharged salt solution, when the stable reading on weighing device is behind an interval, close gas admittance valve, record now reading, finally pass through cubature formula: V=m/ ρ calculates the volume of shale gas, this gauge is simple to operate, test period is short, measuring accuracy is high, reproducible.
