摘要
提出一种基于色彩交会图将致密砂岩四孔隙组分计算值变化映射为色彩变化的测井信息表征方法。该方法通过在HSV色彩空间建立色调、亮度与孔隙组分相吻合的色彩交会图,克服经典着色信息理论的缺陷。利用映射后的丰富色彩表征致密砂岩孔隙度的岩石物性信息,保留原始测井曲线的深度信息,改善测井信息表征方式的直观性和易读性,有效增加测井资料的应用性。在D-T地区的致密砂岩四孔隙组分计算中的应用说明了该方法的可行性和有效性。建立了该地区测井解释标准及油层类别细分模型。
A new representation method of four-porosity components in tight sand is proposed based on colorful crossplot which transforms value of curves into colors. The method overcomes the fault of traditional color information theory by establishing colorful crossplot in which the hue and value correspond to porosity values in HSV color space. The method displays porosity by abundant colors and retains depth of raw curves. The looking directness and understandability are improved and the burden of interpreters is relieved by this method. The application of method in D-T area proves the feasibility and effectiveness of the method. Interpretation standard and oil zone finely classifying model are also established in this paper.
