摘要

基于岩心、测井资料划分了P油田深水重力流水道的岩相与岩相组合类型,总结了重力流水道的沉积相序模式。P油田可划分为3大类岩相(泥岩-粉砂质泥岩及过渡类相,细砂-含砾砂岩相,泥石流和滑塌岩相)12小类岩相以及4大类(重力流水道岩相组合、重力流水道-天然堤岩相组合、重力流水道天然堤-半远洋沉积岩相组合、泥石流与滑塌岩相组合)15小类岩相组合,不同类型岩相与岩相组合的沉积特征与成因环境不同。P油田重力流水道沉积相序模式的下部为重力流水道沉积,向上依次过渡为天然堤、远洋-半远洋沉积。
        Based on core observation and well logging, the lithofacies types and lithofacies assemblage types of deep-water gravity flow channel in P oilfield were comprehensively studied and divided, and the sedimentary facies sequence pattern of deep-water gravity flow channel was summarized. It was divided into three major categories lithofacies types including(silty) mudstone and transitional type class,fine-pebbled sandstone class,mud-rock flow and slump lithofacies class, and 12 small categories of lithofacies types. It was divided into four major categories lithofacies assemblage types including gravity flow channel lithofacies assemblage class, gravity flow channel-natural levee lithofacies assemblage class, natural levee-pelagic and semi-pelagic deposit lithofacies assemblage class, mud-rock flow and slump lithofacies assemblage class, and 15 small categories of lithofacies assemblage types. Different lithofacies type and lithofacies assemblage type have different sedimentary characteristics and genetic environment. The sedimentary facies sequence pattern of deep-water gravity flow channel developed gravity flow channel deposit in the bottom, and change to natural levee and pelagic/semi-pelagic deposit gradually in upward.
