Description
Technical field
The utility model belongs to gas sampling and analytical equipment, relates in particular to the gas on-site sampling in the oil drilling technology, the petroleum gas drilling well sampling analysis device of analyzing.
Background technology
A large amount of gas drilling new technologies that adopt in oil drilling at present, the maximum difficult point of this drilling technology is safety guarantee monitoring method and equipment, promptly toxic and harmful returns out the method and apparatus on the face of land under the monitor well.The landwaste dust that present domestic employing gas monitoring method all needed water filtering drilling well to return out, and guide the gas in the drilling well into the ground collection and detect, and when crossing water filter dirt, the gas that thereupon returns out also will partly or entirely be dissolved in the water, especially gas in the well such as hydrogen sulfide, must filter water-soluble the separating of dirt by the time just separates out after saturated, and the saturated solution of gases such as dissolved hydrogen sulfide has extremely strong corrosivity, force and in observation process, constantly change water, make it to form vicious circle, do not reach the purpose of pernicious gas and fuel gas under the monitor well at all, be difficult to guarantee drilling safety.
Its shortcoming is: adopted water filter dirt mode to detect, and both influenced the accuracy of detection of gas, and caused environment pollution again easily, and can't accomplish the real-time online safety detection, and can't detect gas temperature/humidity index.
The utility model content
The purpose of this utility model provides a kind of petroleum gas drilling well sampling analysis device, does not need water filter dirt mode to detect, and can improve the real-time accuracy of detection of gas, avoids environment pollution, can also detect gas temperature/humidity index.
For achieving the above object, a kind of petroleum gas drilling well sampling analysis device described in the utility model, its key is: comprise Dust filter box, this Dust filter box upper end is respectively arranged with seal cover board, described seal cover board lower surface is equipped with the cloth bag bracket, be covered with cloth bag on this cloth bag bracket, this cloth bag is divided into inner chamber and exocoel with the chamber of Dust filter box; Described seal cover board is provided with out the sample pipe, and this goes out the sample pipe and inserts from the top down in the inner chamber, and described inner chamber is communicated with the external world; The laterally inserted probe tube of the sidewall of described Dust filter box, this probe tube make described exocoel communicate with the external world.
Described Dust filter box cross section is circular, and described probe tube stretches into described exocoel along Dust filter box sidewall tangential direction.
This uses entad sand setting principle of novel employing air whirl.Mine gas enters exocoel along Dust filter box through probe tube by tangential direction, forms eddy current in exocoel, and with the landwaste powder that the carries precipitation that descends naturally in whirlwind, the dustproof cloth bag on the cloth bag bracket intercepts dust outside inner chamber, protects out the cleaning of sample pipe.The cotton antistatic cloth that dustproof cloth bag adopts the wire embedding to knit adheres to reduce dust to greatest extent.
Also be provided with the dust discharge air inlet pipe on the described seal cover board, this dust discharge air inlet pipe makes described inner chamber communicate with the external world, and described Dust filter box lower end is provided with dust outlet tube.
On the described dust discharge air inlet pipe dust discharge admission valve is installed, the dirt valve is installed out on the described dust outlet tube, on the described probe tube sample valve is installed.
The dust overheap is closed sample valve in Dust filter box, opens the dust discharge admission valve and goes out the dirt valve, and the dust discharge air inlet pipe is introduced cleaned air dust is blown into dust outlet tube, by dust outlet tube dust is got rid of.
Also have up big and down small bellmouth on the described seal cover board, be installed with handle in this bellmouth, this handle wall and taper hole wall suit, and handle end hangs described cloth bag bracket.
Be piston-like between handle and bellmouth and cooperate, can manually extract cloth bag bracket and dustproof cloth bag that the handle shake is hung, to shake out the accompanying dust of cloth bag external surface.
On the described probe tube pressure sensor is installed.
Utilize the laying dust in two kinds of dust removing funnels of pressure sensor signal control eliminating.When the termination of pumping of sample gas drilling well intermittently, pressure sensor provides and stops boring signal, when probe tube upward pressure signal is lower than 5KPa, dust discharge admission valve and go out the dirt valve and open, sample valve cuts out, and forms the dust discharge passage.At this moment, compressed air is blown into Dust filter box by the dust discharge air inlet pipe, and drains through the dust outlet tube of Dust filter box bottom.When probe tube upward pressure signal during more than or equal to 5KPa, pressure sensor provides and stops boring signal, dust discharge admission valve and go out the dirt valve and close, and sample valve is opened, the device sampling work.
Remarkable result of the present utility model is: adopt dry type air blowing mode to filter dirt, avoid pollution to sample gas, can improve the accuracy of detection of gas, avoid environment pollution, can be for the down-hole: parameters such as gas pressure, gas flow, gas temperature, gas humidity, hydrogen sulfide relative amount, hydrocarbon gas relative amount, oxygen relative amount, carbon monoxide relative amount, carbon dioxide relative amount, hydrocarbon gas concentration are carried out online in real time and are detected.
