摘要
应用丰富的岩心资料、测井资料以及录井资料,通过岩心观察描述以及沉积相分析方法,深入开展鄂尔多斯盆地合水地区长6油层组储层的沉积相类型及相模式等研究。通过岩石类型、沉积结构、构造、古生物以及沉积环境分析,认为长6油层组沉积时期主要发育陆相湖盆深水浊积扇相,并可划分出内扇、中扇和外扇等3个亚相;通过沉积相及测井相等分析方法,以明确沉积相平面展布以及垂向演化规律,最终建立了研究区长6油层浊积扇相模式。
Through core observation and description and sedimentary facies analysis,and with rich core data,logging information and logging data, the sedimentary facies types and facies patterns of the reservoir in the Chang 6 formation are studied in depth. Based on the analysis of rock type,sedimentary structure,sedimentary tectonics,paleontology and sedimentary environment,it is concluded that the sedimentary period of Chang 6 formation mainly developed the terrestrial lacustrine turbidite fan facies in deep water,and could be divided into three subfacies:inner fan,middle fan and outer fan. The turbidite fan facies model of Chang 6 reservoir in the study area was finally established through the analysis of sedimentary facies and logging equivalence to clarify the planar distribution and vertical evolution of sedimentary facies.
