    摘要:

    测井地质学以地质学和测井学的方法理论为指导,综合运用各种测井信息,来解决基础地质和石油地质的地质问题。经过数十年发展,测井地质学在油气勘探开发各个环节得到广泛应用。非常规油气的兴起使得测井地质学正面临多重挑战和全新探索,亟需建立针对非常规油气的测井地质学综合方法理论体系。本文以《测井地质学·第二版》出版为契机,系统归纳了测井地质学的起源及发展历程、主要研究内容和研究方法流程。然后总结了测井资料与地震、地质信息的匹配性,并分析了不同探测特性测井方法纵向分辨率区间特征。在此基础上评述了测井地质学在井旁构造解析、沉积学特征研究、层序地层划分、地应力方向判别及大小计算、井壁裂缝识别与评价、烃源岩评价以及非常规油气“七性关系”综合评价当中的应用。但由于测井资料的负载能力有限性、测井与地质信息属性不对应性以及测井资料本身的多解性,使得测井地质学在测井—地质转换、非常规油气测井评价及其与人工智能融合方面还存在一定的问题。因此加强基础岩石物理研究,挖掘测井曲线中包含的地质信息,并与人工智能相结合,将拓展测井地质学研究的精度和广度,从而使其未来可更好地应用至非常规油气测井评价等实践工作中。

    Abstract:

    Well logging geology is guided by the theories of geology and well logging which comprehensively uses various well log data to solve problems existing in basic geology and petroleum geology.Well logging geology has been widely used in the various aspects of oil and gas exploration and development in the past decades.With the rise of unconventional hydrocarbons,well logging geology is facing multiple challenges and new explorations,and it is urgent to establish a comprehensive method and theoretical system of well logging for unconventional hydrocarbons.This paper takes the publication of “Well Logging Geology: Second Edition” as an opportunity,and systematically generalizes the origin,development,the main research contents and research method flows.Then it summaries the matching relationships of well log data with seismic data and geological information,and the features of the vertical resolution interval of logging methods with different detecting characteristics are analyzed.Then,the applications of well logging geology in the analysis of borehole structure,sedimentary characteristics research,sequence stratigraphic division,in situ stress direction determination and calculation of in situ stress magnitude,identification and evaluation of wellbore fracture, evaluation of source rocks and “seven properties relationships”of unconventional oil and gas resources.However,due to the limited load capacity,the inconsistency of logging and geological information,and the ambiguity of logging data itself,there are still some problems existing in well logging geology conversion and the fusion of unconventional hydrocarbons logging evaluation and artificial intelligence.Therefore,strengthening the basic petrophysical research and mining the geological information in the logging curves integrated with artificial intelligence will definitely expand the accuracy and width of well logging geology,therefore it can be better applied to the unconventional hydrocarbons evaluation.
