A3M联测技术在岩芯分析中的研究及应用

STUDY AND APPLCATION OF A3M ASSOCIATION MEASURING TECHNOLOGY IN CORE ANALYSIS

总结国内外岩芯分析技术，综合应用现代控制论、信息论、系统工程论的基本原理，提出A3M理论性认识和联测技术的新概念，研制出一套具有多学科、多目的（任务）、多项目（参数）的岩芯综合分析技术，即岩性、物性、岩石电性、声波等联测的技术．完成了一套与联测技术流程相配套的实用软件包，这套技术提供了系统的、有代表性的、可对比的岩芯分析资料，可直接用于油田现场与实验室岩芯分析生产、科研和管理及油田的开发中，有利于认识非均质储层岩石地质、物理特征以及各种信息之间的内在规律．

Based on wordwide technology of core analysis, integratively combined with basic principles of modern cybernatics, information theory and system engineering, A3M theory and association measuring technology is proposed in this study. The association measuring technology for core analysis of multiple disciplines, mu1ti-objectives, multi-items for one sample under same condition is created' For example, technic for the simultaneous measurement of the resistivity parameters (m. n) and the water -oil relative permeability, tecboc for the simultaneous measurement of capillary pressure curve (by send-permeable membarane method) and the resistivity paramters; technic for the simultaneos measurement of elastic moduli of acoustic dynamics and statics, acoustic wave and porosity under high pressure; technic for the simultaneos measurment of lithology, physical properties, and electrical properties and acoustic wavel technic for the simultaneous measurment of cation exchange caPacity (CEC) of arglllaceous sandstone samples and lithology, physical properties, and nature Y energy spectrum. The technology engineering provides a set of comparable, ecnomical and practical core analysis dada, flowchart and comput software for production and research of exploration and development of oil field. lt can be used directly for important sighficant for cost effective exploration and development of hydrocarbon resorces.
