摘要: R/S分析是一种描述及评价一维时间序列复杂性的分形方法,文中通过理论分析及实际实验,讨论了R/S分析对储层垂向非均质性和裂缝发育程度的描述能力,并从不同的测井参数序列所反映的储层地质特征不同出发,论证了运用声波时差与自然伽马两种参数序列的分维差值进行层段裂缝发育程度评价的可行性。该方法可以有效地排除岩性的影响而突出裂缝的特征,较之单序列分析理论上更新颖,实际评价效果更好。Abstract: R/S analysis is a kind of fractal method to describe and evaluate the complexity of 1-dimension parameter series,based on research of theoretical analysis and practical experiment,this paper discussed about the capability of R/S analysis in describing vertical reservoir heterogeneity and fracture development,and through discussing the difference of reservoir geologic characteristics embodied by different log curves,this paper demonstrated the feasibility of using the fractal dimension difference between AC and GR log curves to evaluate fracture development quantitatively. This method can effectively eliminate the lithological influence but highlight the characteristics of fracture, it has a novel pattern theoretically and shows much better evaluating effects than that of single series analysis.
