综合利用岩心、测井、分析化验、三维地震等资料，对莺歌海盆地LD15-1气田分气组建立了高分辨率等时地层格架，识别出一种沉积相(无障壁海岸相)、两种亚相(临滨亚相、滨外亚相)、三种微相(临滨坝、滨外滩、滨外泥)，建立了垂向沉积演化模式。参考三维地震资料，绘出了主力气组的沉积微相平面图。

Based on the data of core analysis and logging and 3D seismics, a high- resolution isochronal stratigraphic framework is set up for each gas pay bed in LD15-1 Gas Field in Yinggehai Basin. One sedimentary facies (non- barrier coast facies), two subfacies (shoreface and offshore subfacies) and three microfacies (shoreface bar, offshore beach and offshore mud microfacies) are identified. As a result, a model of vertical sedimentary evolution is proposed and the distribution maps of sedimentary microfacies for main gas pay beds are described.
