The invention relates to a spectrum continuous gas logging device and a method. The spectrum continuous gas logging device comprises an air extracting pump, a gas distribution module, an alkane component gas detection module, a carbon dioxide gas detection module, a carbon monoxide gas detection module, a hydrogen sulfide gas detection module, and a computer control system. Base data of a standard gas is measured and stored in the computer control system at first by utilizing the spectrum continuous gas logging device. Sample gases in drilled formation fluid brought by circulating drilling fluid are continuously sampled by an electric degasser. Every gas component in the sample gases is continuously detected through spectroscopy by the spectrum continuous gas logging device. A spectrum logging software of the spectrum continuous gas logging device uses the standard gas base data for realtime detection of alkane, carbon monoxide, carbon dioxide, and hydrogen sulfide gas content information in drilling formation liquid, formation liquid properties are rapidly explained by the spectrum logging software, and spectrum continuous gas logging is realized.
Description
technical field [0001] The invention relates to a continuous gas logging device and method in the process of petroleum exploration and development, and belongs to the technical field of mud logging in the process of petroleum exploration and development. Background technique [0002] Gas logging is an important means to detect and judge the properties of formation fluids encountered during oil exploration and development. The traditional gas logging device and method is to use gas chromatography technology, and a gas chromatography logging device has been developed to detect the content information of methane, ethane, propane, butane, pentane and other alkane components in the formation fluid encountered; using TCD The thermal conductivity detection device detects the content information of carbon dioxide in the formation fluid encountered, and uses the electrochemical method to detect the content information of hydrogen sulfide gas. [0003] Traditional gas logging and mud...
