Abstract: This MGIL (Mud gas isotope logging) was a newly emerged well logging technique. The conven-tional isotopic analysis in China was normally offline in the laboratory, and thus it cost much time and money. Though measuring online, Geoisotope used in Sino-France geological isotope logging service could only test methane isotope data, and it was larger in size and susceptible to the influence of external environment. The mud isotope logger, isologger developed by the British CSS (Compact Science System) Company, equipped with Isotope-ratio mass spectrometry (called IRMS), was smaller in size, higher in accuracy, and less susceptible to the influence of external environment, in which a gas chromatogram separation unit was rationally introduced. Thus the Isologger could measure isotope data of C1-C5 online, and it enriched the isotope information to mud log. Based on isotope data of multiple components, hydrocarbon maturity analysis and down hole oil formation analysis can be carried out locally, which greatly enhances the guidance function of mud logging. Isotope logging has bright application prospects in deep sea area, unconventional reservoirs, and high temperature, high pressure and high sulphur content reservoirs.
