In the process of performing the above-mentioned sectional type multiple sampling, an operator adjusts the rotation frequency of the first conduit 401 according to the actual pressure in the conveying pipe 101, so as to control the single sucking of the gas samples with different volumes, improve the applicability of the device, and improve the reliability of the sampled product, so that the sampled product provides more accurate and representative data.
Referring to fig. 2 and 3, the air conditioner further comprises a second fixing frame 8 fixedly connected to the first fixing shell 105 and slidably connected with the conveying pipe 101, wherein the second fixing frame 8 is provided with a plurality of limiting holes, a second limiting rod 801 is slidably arranged on the conveying pipe 101, a tension spring is arranged between the second limiting rod 801 and the conveying pipe 101, the second limiting rod 801 is in limiting fit with the adjacent limiting holes on the second fixing frame 8 and is used for limiting the limiting positions of the second fixing frame 8 and the conveying pipe 101, and the central line of the first guide pipe 401 is inclined relative to the central line of the conveying pipe 101 and is used for guiding air to flow obliquely.
In the above scheme, the length of the second guide tube 402 inserted into the conveying tube 101 is controlled by controlling the limiting holes of the second limiting rod 801 inserted into different positions on the second fixing frame 8 by an operator, so that the sampling of gas media in different areas is realized, the comprehensiveness of the sampled product of the device is improved, the comprehensiveness of the subsequent test result is improved, the central line of the first guide tube 401 is inclined relative to the central line of the conveying tube 101, the gas flow is conveniently guided, and the residue and stagnation of the gas in the first guide tube 401 in the sampling process are reduced.
Embodiment 4 the present invention further provides a method for efficient sampling of an oil and gas field development gas phase tracer, based on the above-mentioned efficient sampling device for an oil and gas field development gas phase tracer, based on the basis of embodiment 3, as shown in fig. 1 to 7, comprising the following steps:
S1, before sampling, adjusting the position of a limiting hole inserted into a second fixing frame 8 by a second limiting rod 801 according to a sampling area, namely adjusting the length of a second guide pipe 402 in a conveying pipe 101;
s2, after the position of the second guide pipe 402 is adjusted, the first limiting rod 601 is pulled to control the second sliding column 5 to move, so that the second sliding column 5 slides out of the second through hole of the sliding plug 107, namely the limiting of the sliding plug 107 is released;
S3, after the second sliding column 5 is moved, the tank 108 is installed on the second fixed shell 106 in a threaded manner, after the tank 108 is installed, the second fixed shell 106 moves the sliding frame 3 through the sliding rod 301, the sliding frame 3 moves to release the limit of a blind hole on the first sliding column 2, and then the first sliding column 2 moves and presses the sliding plug 107 to move until a communication hole on the first sliding column 2 is communicated with the second fixed tube 4;
S4, when the second guide pipe 402 does not contact the fixed seat 7, the gas medium flowing in the conveying pipe 101 enters the tank 108 through the first guide pipe 401, the second fixed pipe 4 and the first through hole on the second fixed shell 106 and the communication hole of the first sliding column 2 along with the installation of the tank 108;
S5, when the second guide pipe 402 contacts the fixed seat 7, the gas medium flowing in the conveying pipe 101 can only enter the tank 108 through the first gas guide hole 701, the second gas guide hole 702, the first guide pipe 401, the second fixed pipe 4 and the first through hole on the second fixed shell 106 and the communication hole of the first sliding column 2 along with the installation of the tank 108;
S6, in the S5 step of the gaseous medium, the power piece 703 is controlled to work, the power piece 703 is controlled to rotate through the rotating shaft 704 and the gear set, and the gaseous medium is controlled to intermittently flow into the tank 108;
S7, after the step S4 or the step S5 is carried out for a period of time, the tank 108 is filled with a gas medium, then the sliding plug 107 is pressed and the first sliding column 2 is pulled to reset, then the second sliding column 5 is controlled to reversely move and insert into the second through hole of the sliding plug 107, the second fixed pipe 4 and the first guide pipe 401, then the tank 108 is reversely rotated, the tank 108 is removed from the second fixed shell 106, and meanwhile, the sliding frame 3 is reinserted into the blind hole of the first sliding column 2;
s8, marking the sampling time on the tank 108 after the quantitative gas medium is taken out from the tank 108.
The above description is merely illustrative of the embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope provided by the present invention, and the invention should be covered.
