本文以辽河西部凹陷高升油田二、三区莲花油层５、６砂岩组为例，在岩心观察基础上，收集储集砂砾岩体成因标志，结合测井定量信息，应用开发储层小层细分沉积微相研究方法，建立了断陷湖泊深水环境中重力流辫状水道沉积模式，阐明了砂砾岩体在空间上的分布规律及其演化特征，指出了沉积相带对储层性质的控制作用。本文还探讨了深水辫状重力流水道砂砾岩体的形成与断裂构造、古气候和古地理条件的关系。
Taking the No.5 and No.5 sandstone reservoirs in the second and third districts of Gaosheng Oilfield in the western Liaohe Sag as an example, based on the core observation, the genetic markers of reservoir glutenite bodies are collected. Based on the logging quantitative information, Sedimentary microfacies research methods, established gravity flow braided channel sedimentary model in deep water environment of rifted lakes, elucidated the spatiotemporal distribution rules and evolution characteristics of glutenite bodies, and pointed out the controlling function of sedimentary facies on reservoir properties. The paper also discusses the relationship between the formation of deep-water braided gravity flow channel glutenite body and the fault structure, palaeoclimate and palaeogeographic conditions.
