| titleOfInvention | Method for measuring carbon dioxide in aeration zone |
| abstract | The invention discloses a method for measuring carbon dioxide in an aeration zone, which comprises the following steps: (1) according to the research purpose, the research range is determined, and the aeration zone CO is completed 2 Arranging concentration measuring points; (2) assembling a carbon dioxide measuring device of an aeration zone, selecting a certain measuring point, controlling a drill rod and a drill bit to rotate clockwise by operating a rotating handle, enabling the drill bit to drill downwards, plugging an air intake port by the movable plug, controlling the drill bit to rotate anticlockwise by a certain angle by reversely operating the rotating handle when the drill bit drills to the measuring position, opening the air intake port, and starting the carbon dioxide measuring device to pump out carbon dioxide in the aeration zone through the air intake port, a carbon dioxide air intake channel and a carbon dioxide conveying gas pipe and measure the concentration; (3) and (4) sequentially completing the carbon dioxide gas concentration measurement of each measurement point according to the designed sequence of the measurement points. The invention can measure the concentration of carbon dioxide in the process of drilling, is suitable for flexible measurement of the area aeration zone with indefinite points and indefinite depths, and has small measurement error. |
