根据层序地层学及动力沉积学原理，结合开发层系需要，将齐１０８块莲花油层分为３个油层组１０个砂岩组，该油层可识别出Ｇｍ，Ｓｓ，Ｓｍ，Ｓｍｇ，Ｓｐ，Ｓｗ，Ｓｈ，Ｓｒ，Ｆｍ，Ｆｆ和Ｆｄｓ等１１种岩石（性）相，它们构成了二级扇三角洲沉积模型，细分出水下分流河道、前缘砂坝等７种沉积微相，利用古河道趋势分析法，编绘了不同时期砂体的分布网络及沉积微相图，砂体分布明显受控于水下分流河道的展布趋势，不同级别水下分流河道砂体构成了研究区的主要储集层，控制了储层的非均质性，并讨论了沉积微相研究在油田开发中的作用。
According to the theory of sequence stratigraphy and dynamic sedimentation, combining with the needs of the development strata, Qi 108 block oil reservoirs are divided into 10 sandstone groups of 3 oil layer groups. Gm, Ss, Sm, Smg, Sp, Sw , Sh, Sr, Fm, Ff and Fds. They constitute the second-level fan delta sedimentary model, and subdivide seven sedimentary microfacies, such as underwater distributary channel and frontal sand bar, Trend analysis method, the distribution network and sedimentary microfacies map of sand bodies are compiled in different periods. The distribution of sand bodies is obviously controlled by the distribution trend of underwater distributary channels. The different grades of distributary channel sand body make up the main The reservoir controls the reservoir heterogeneity and discusses the role of sedimentary microfacies in oilfield development.
