摘要
利用镇泾油田37口井的岩心资料和EMI微电阻率成像测井资料来确定岩性相标志特征,系统地对长81段储层进行划分和对比,建立了地质-测井的沉积微相模式,在单井沉积微相分析、对比和多井连井剖面对比图的基础上,通过沉积相相标志物的层次结构分析法和沉积体系分析法,结合测井相分析等多学科综合研究方法,确定了研究区沉积相及砂体的空间展布规律,绘制了延长组长81段油层组沉积微相平面分布图,从而划分出有利的油气富集区,为油田合理开发提供了技术支持。
Use coring data of 37 wells in Zhenjing oilfield and EMI logging data to determine lithologic facies features,divide and compare Chang 81 member systematically,set up geology-logging sedimentary facies mode.Based on analyzing and comparing single well sedimentary micro facies and multi connecting well profile,according to spectra feature analysis and sedimentary systematic analysis of sedimentary facies marker,combined with logging facies analysis,the space distribution of sedimentary facies of study area has been determined,extension formation Chang 81 member oil layer sedimentary micro facies plan distribution have been drew up.Which divided the advantageous oil gas enrichment region,and provided the technical support for the oil field reasonable development.
