Abstract

Abstract

The development and application of shale gas mud logging technology has enhanced constantly with technology research for more than ten years. Based on the evaluation demand of geological engineering integration technology， the paper has summarized a characteristic series of shale gas logging technology， namely，hydrocarbon source rock property evaluation by combination of the rock pyrolysis mud logging method and the natural gamma ray spectrometry mud logging method， shale lithology and brittleness evaluation by combination of element mud logging and natural gamma ray spectrometry mud logging， shale gas-bearing evaluation by combination of gas mud logging and carbon isotope mud logging， and shale physical property evaluation mainly by nuclear magnetic mud logging. Meanwhile， the paper predicts the development of shale gas mud logging technology. Nowadays，it faces the technical problems of complex horizontal shale gas well exploration targets， higher temperature of deep shale gas formation and lower pressure of normal pressure shale gas formation； thus， it is necessary to constantly improve the resolution of logging instruments， to strengthen innovation of multi-dimensional nuclear magnetic mud logging methods and other new technologies. In order to realize the three-dimensional portrayal and precise evaluation of shale gas formation， the big data resources should be used to develop intelligent mud logging technology so as to provide comprehensive technical support for efficient and high-quality shale gas exploration and development.
