FAST MUD GAS LOGGING USING TANDEM MASS SPECTROSCOPY |
摘要 |
Systems and methods for high speed mud gas logging are described. A general workflow of mud gas logging uses tandem mass spectroscopy. The workflow involves first separating the volatile components of the hydrocarbons (typically C8 and below) from the drilling fluid using a fluid extractor (or degaser). Extracted gases are then diluted in air and transported to an analyzer, which measures the concentration of each of those gases in air. A tandem mass spectroscopy-based analyzer is used that is able to quantify each of those hydrocarbon components, including resolving isomeric species, while tolerating the presence of the non-hydrocarbons. According to some embodiments, triple quadrapole mass spectroscopy is used. |
