Research and application of evaluation hydrocarbon logging technology

To solve the problems of inaccurate oil and gas shows identification and low interpretation consistency rate caused by complex reservoirs, a series of new evaluation logging technologies were introduced, and the related basic theory exploration and application research work were carried out. The problem of inaccurate oil and gas identification under complex working conditions was solved through comprehensive application of quantitative fluorescence and fluorescent microscopic image logging techniques. Comprehensive interpretation consistency rates of complex water/oil bed and complicate layers with oil and gas shows were increased by the research and application of light hydrocarbon component analysis and evaluation techniques. By a comprehensive adoption of light hydrocarbon components, nuclear magnetic resonance, quantitative fluorescence and fluorescence microscopic image logging evaluation techniques, the jobs of reservoir properties evaluation, oil/gas shows and oil-water interface determination have achieved good results in buried hill exploration. In the past three years, research and promotion of evaluation logging ensured the 100% rate of logging oil/gas show recognition and a steady increase in interpretation consistency of the integrated reservoir logging.
