摘要

描述了一种新的算法支持核测井(CNL或SNP, NGRS或NGR, FDL)数据的操作岩石物理解释方法。单个解释的原始模块通过径向灵敏度和不同层位的整体径向几何因子考虑了工具-井-床系统的径向非均质性。对于复杂的解释，采用了自适应岩石物理调整和地质剖面初步分类的分量分析方法。通过确定矿床的矿物组成，并根据评价的动态孔隙度进行岩石物理过滤，获得了可靠的储层提取方法。本文介绍了西西伯利亚秋明套陆相矿床成分分析的一些结果。

Operative Petrophysical Interpretation Of The Nuclear Well Logging Data

A new approach to algorithmical support for operative petrophysical interpretation of nuclear well logging (CNL or SNP, NGRS or NGR, FDL) data is described. Original modules of individual interpretation takes into account radial heterogeneity of a tool-borehole-bed system by radial sensitivity and integral radial geometric factors for different zones. For complex interpretation componential analysis method with adaptive petrophisycal tuning and preliminary clastering of the geological section are used. Reliable extracting of reservoirs is obtained by determining of mineralogical composition of deposits and by petrophysical filtration according to evaluated dynamic porosity. Some results of the componential analysis for terrigeneous deposits of Tyumen Suite (West Siberia) are presented.
