By means of lots of information about mud logging technology in hand, through research for reservoir type in home and abroad and phase state prediction theory, analyzed the present states and problems in deep-seated hydrocarbon exploration & development in Qiaobai Area, studied on formation fluid component characteristic, temperature-pressure characteristic, mud logging response characteristic etc. in deep-seated reservoir in Qiaobai Area, analyzed the geological evaluation meanings of logging data from cuttings logging, fluorescence logging, drilling fluid logging, gas logging, pyrolysis gas chromatographic logging, lighter hydrocarbons logging according to well testing result, optimized seeking characteristic parameter, formed mud logging evaluation method for deep-seated reservoir types and hydrocarbon property in Qiaobai Area, formulated a quantitative evaluation standard, This result realized a rapid & exact evaluation for deep-seated hydrocarbon property in Qiaobai Area ,offered technical assist for the deep-seated hydrocarbon exploration and development in detail design. it is improved by application in site in return.
