摘 要: 针对N国A地区储层复杂、泥质含量高、水性变化大等因素引起的低阻油藏评价难题,在对其常规测井资料响应差异深入分析的基础上,总结并提取出量化表征岩性、物性和含油性的敏感参数系列。通过对参数系列的归一化、界限响应确定及界限刻度对齐,集成并构建出储层特征的直观描述谱,从而形成了一种快速直观的测井解释技术。对A地区的油气藏进行处理解释应用,符合率高达86%,为复杂地区测井快速直观解释提供了新的思路。
关 键 词: 固体地球物理学;属性谱;快速直观解释;低阻油层

Abstract: Regarding the evaluation problems of low resistivity reservoirs caused by complex reservoir, high clay content, and large water change in area A, state N, based on the in-depth analysis of the response differences of conventional logging data, series of sensitive parameters of lithology, physical property and oil bearing are summarized and extracted in the paper. Through the normalization of the parameter series, the determination of the threshold response and the re-calibration of the threshold scale, the direct description spectrum of reservoir characteristics is integrated and constructed, thereby forming an efficient and intuitive logging interpretation technique. The hydrocarbon reservoirs in area A are processed and interpreted with the method above mentioned with a coincidence rate of 86%, which provides a new way for the fast and intuitive logging interpretation of the complex area.
Key words: solid earth geophysics; attribute spectrum; efficient and intuitive interpretation; low resistivity oil layer
