| 摘 要： | 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。

| Abstract: | The Lianhua sandstones 5、6 in areas 2、3 of Gaosheng oilfield in the western Liaohe depression were discussed in this paper. On the basis of study of cores, various geneticcriteria and the quantitative logging information, using method of sedimentary microfaciesfor reservoir development, a braided channel model of gravity flows in deep lacustrine environment was built and the spatial distribution and evolution of the sand-conglomeratebodies were clarified. It was pointed out that reservoir properties were controlled by sedimentaty factes. In addition, the relationship among the formation of the sand-conglomerate bodies of the braided gravity flow channel in the deep water, fault structures, palaeoclimate and palaeotopography was disscussed. |
