| 摘 要： | 通过对下寺湾油田长6段已知油藏沉积相、沉积微相的研究分析,认识到低孔、低渗油田有利储层分布主要受沉积相带的控制,本地区三角洲前缘亚相的分流河道和河口坝微相是主要的储集层,同时油气富集也受局部微幅度构造的影响。本区生、储、盖组合关系良好,具备形成大规模油藏的条件,在勘探方向上以已知油藏为中心,向东、西两侧进行勘探,将会有更大发现。

| Abstract: | Study on sedimentary facies and microfacies of the known reservoir of the Chang 6 member of the Yanchang formation in the Xiasiwan Oilfield indicates that the dominant reservoirs are distributary channels and river mouth bar microfacies in the delta frontal surfaces of this region.Also,the accumulation of oil and gas is controlled by gentle structures.And find that source bed,reservoir and cap rocks are in a excellent combination,providing conditions for large-scale hydrocarbon accumulations.The exploration should be planned around the identified pool and then extended to both east and west in direction. |
