DETECTION AND ANALYSIS OF METHANE IN THE FORMATIONS OF METHANE COAL STRAYS |
| abstract |
A measuring system is presented for measuring in well 1 using a spectrometer 4. Spectrometer 4 includes a radiation source 5 and a detector 6. Sensor 15 has an optical connection with spectrometer 4 and includes an optical waveguide 7 for transmitting radiation from the radiation source 5 and at least the second optical a waveguide for transmitting the characteristic radiation from the sample to the detector 6. A positioning device is provided for positioning the sensor 15 near the lateral surface 11 of the bore 3 of the well and for the optical connection The optical waveguides 7 have a side surface 11, while the sensor 15 can move up and down the borehole 1 using a guide having a movable connection with the sensor 15 and a fixed position at the wellhead. The use of the device and method according to the invention makes it possible to determine the concentration of methane or another substance of interest, and thus the potential reserves of the methane formation in the coal seam.
