摘要
为了促进涠西南凹陷涠洲10-3油田及围区流三段油藏的滚动勘探开发,开展了油区沉积相精细研究。利用岩芯、录井、测井和地震等资料,在识别不同级别层序界面和湖泛面的基础上,将涠洲10-3油田及围区流三段划分为2个长期基准面旋回和8个中期基准面旋回,建立了高分辨率层序地层对比格架。在岩芯描述基础上,进行单井沉积相、连井沉积相、平面沉积相分析,认为研究区流三段发育冲积扇、扇三角洲和湖泊3种沉积相,并系统划分了沉积微相类型。探讨了碎屑流沉积的相带归属,将发育在河道中的碎屑流沉积划分为河道型碎屑流沉积,将单独产出的碎屑流沉积根据沉积环境不同划分为水上非河道化碎屑流沉积和水下非河道化碎屑流沉积。最后对各中期基准面旋回的沉积相展布特征和演化规律进行了探讨,并建立了符合研究区的沉积相模式。
In order to promote progressive exploration and development in WZ10-3 Oilfield and surrounding area,the fine sedimentary facies study in oil region was carried out.Guided by the high resolution sequence stratigraphy theory,in combination with core,logging,log and seismic data,on the basis of recognition of different levels sequence interfaces and the types of maximum lake flooding surface,the Member 3 of Liushagang Formation can be divided into two long-term base level cyclical sequence and eight middle-term base level cyclical sequence.By analyses of individual well sedimentary facies,section sedimentary facies and plane sedimentary facies,3 sedimentary facies of alluvial fan,fan delta and lacustine were identified in the Member 3 of Liushagang Formation,and microfacies were divided,facies belt ownership of debris flow deposit was discussed systematically.Debris flow deposits developing in channels were divided into 3 types,i.e.,channels,distribution channels and subaqueous distribution channels microfacies.While individual developmental debris flow deposits were divided into 2 types,i.e.,subaerial non-channelized and subaqueous non-channelized debris flows microfacies.On the basis of these,sedimentary facies distribution and sedimentary evolution rule of MSC1 to MSC8 of the Member 3 of Liushagang Formation were discussed,and sedimentary models were established finally.
