Description
Technical field
The present invention relates to a kind of device for collecting sample in Oil And Gas Geochemical Exploration technical field, being specially a kind of device collected for gas sample, shift and preserve.
Background technology
In oil and gas geochemical exploration Specimen Determination, gas sample and lighter hydrocarbons hydro carbons calibrating gas are all inject with drainage the airtight container filling with supersaturation sodium chloride solution, for mensuration.Extensively adopt in the bucket filling water (or supersaturation sodium chloride solution) or basin at present, put into vaccine bottle or saline bottle, after draining air, collect gas with drainage, then seal with rubber stopper.During test, then get gas analysis from vaccine bottle or saline bottle.
Adopt above-mentioned vaccine bottle or saline bottle to collect, preserve the operation in water (or supersaturation sodium chloride solution) of gas needs, easily cause gas sample to lose, efficiency is not high; And reuse due to water (or supersaturation sodium chloride solution), the gas group branch in high-load sample pollutes low content gaseous sample; If each gas sample just changes water (or supersaturation sodium chloride solution) after collecting, waste can be caused again; And this vaccine bottle or saline bottle are collected, when preserving small size gaseous sample, operating difficulties; Meanwhile, small size gas sample collection after preserving comparatively hard-pumped get gaseous sample and carry out instrumental analysis.
Summary of the invention
For the problems referred to above existing in prior art, propose a kind of device for collecting sample.This device for collecting sample avoids collects gas in water (or supersaturation sodium chloride solution), makes operation simpler.
According to the invention provides a kind of device for collecting sample, it comprises the container for depositing sample, the container cover be connected with seal of vessel, be arranged in container cover with the first opening of reservoir and the second opening, and for the first gland bonnet of sealing the first opening and the second opening respectively and the second gland bonnet, first gland bonnet and the second gland bonnet all arrange through hole, between the first opening and the first gland bonnet and between the second opening and the second gland bonnet, sealing gasket is set respectively, wherein, second opening is liquid discharge entrance, first opening is gas inlet-outlet, the communicating pipe be communicated with the second opening enclosure-type is set at the second opening part.When collecting gas sample, after making the full liquid (liquid is herein water or supersaturation sodium chloride solution) of container content, open the second gland bonnet again, then the sealing gasket of the first opening part can be pierced through to injecting gas sample in container with hollow needle, now, under the pressure of the gas, water (or supersaturation sodium chloride solution) is discharged by communicating pipe and the second outward opening.Thus completing the collection of gas, this process does not need to collect gas sample in the bucket or basin of filled with water (or supersaturation sodium chloride solution), simple to operate.When tightening the first gland bonnet and the second gland bonnet, gas sample can store in a reservoir, can be used for storage and the transport of gas.When needing to carry out instrumental analysis to the gas sample preserved, Available trace injector or syringe gather gas from the first opening.Make container content full water (or supersaturation sodium chloride solution), container cover can be opened, container and container cover are put into the bucket or basin of filling water (or supersaturation sodium chloride solution), seal by container cover after draining air.The first gland bonnet can also be opened, inject water (or supersaturation sodium chloride solution) from the second opening, drain air from the first opening, make in device, to be full of water (or supersaturation sodium chloride solution).Thus, this device is suitable for gas sample and collects, and is applicable to transfer and the preservation of gas sample simultaneously, is particularly useful for adopting drainage Collection and conservation gas.And this device is not restricted to the volume of Collection and conservation gas sample, be applicable to collect, preserve all kinds of different volumes gaseous sample, avoid the problem such as operating difficulties when prior art preserves small size gaseous sample.
In one embodiment, the height of the second opening is higher than the height of the first opening.When adopting drainage Collection and conservation gas, the gas of energy assurance device inside is barotropic state, thus the gaseous sample be convenient to microsyringe or syringe are preserved from the first opening collection is analyzed.
Preferably, the first end of communicating pipe is fixedly connected with the second opening, and second end of communicating pipe and the diapire of container close on.When drainage collects gas, second end of communicating pipe and the diapire of container close on and are conducive to water (or supersaturation sodium chloride solution) to displace container, make container store up more gas, thus take full advantage of container.
Preferably, the diapire of container arranges the recess being beneficial to liquid accumulation, and second end of communicating pipe is arranged in recess.When drainage collects gas, the water (or supersaturation sodium chloride solution) contributed in container displaces container more fully.
Preferably, the high 0.2 ~ 5cm of height of aspect ratio first opening of the second opening.While this set gas met in container is barotropic state, make gas pressure suitable.
Preferably, the first end of communicating pipe and the second opening bond.This arrangement ensure that being communicated with of communicating pipe and the second opening.Meanwhile, its structure is simple, convenient manufacture.
Preferably, second end of communicating pipe is set to the end face with inclination.This set is conducive to water (or supersaturation sodium chloride solution) and more easily enters or flow out communicating pipe.
Preferably, communicating pipe is manufactured by polycarbonate.
Compared with prior art, the invention has the advantages that, this this body structure of device is simple, and cost is low; When drainage collects gas, avoid operation in the bucket or basin of filled with water (or supersaturation sodium chloride solution) and collect gas, the good work environment of operating personnel, reducing running cost; Use this device to collect, preserve gas-operated is simple, be applicable to gaseous sample in enormous quantities collection, preservation; Be applicable to collect, preserve different volumes gaseous sample; Be easy to the storage and transport of gaseous sample simultaneously, and can Reusability.
