Abstract

The traditional logging FID technology, which achieves a 30 second cycle detection of methane to pentane can no longer fully meet the identification and discovery of thin layers, fractures, etc. under fast drilling conditions. We have conducted research on intelligent optical spectroscopy logging technology, developed a mixed gas quantification algorithm based on calibration curves, proposed net spectrum extraction technology and nonlinear spectrum reconstruction technology, successfully solved two problems including absorption spectrum cross interference and nonlinearity, and achieved overlapping peak decomposition and accurate quantification. It can detect methane, ethane, propane, i-butane, n-butane, i-pentane, n-pentane, carbon monoxide, and carbon dioxide with a minimum detection of 0.0010%. The detection cycle for methane to pentane is only 10 seconds, making it more suitable for oil and gas identification under rapid drilling conditions.
