| 摘 要： | 胜利油区五号桩油田桩74块为湖底扇沉积,根据岩心、粒度分析及测井等资料详细描述开发井集中的中扇辫状水道微相、中扇水道侧缘微相、中扇朵叶体微相的沉积特征.在对处于不同沉积微相的生产井定量分析的基础上,总结出特低渗透条件下湖底扇不同沉积微相的开发特征,通过实验认识到不同沉积微相所表现出迥异不同的开发特征根本原因是不同微相带启动压力梯度差异的体现,动静态资料结合进一步阐明了湖底扇特低渗透油藏不同沉积微相带剩余油分布规律,认为中扇辫状水道微相是剩余油富集主要微相带.

| Abstract: | Zhuang 74 fault block of WuHaoZhuang oilfield in Sheng Li oil region is the sublacustrine fan deposition.Based on core and well logging data,sedimentary characters of braided channel,channel edge and lobe,where most production wells are concentrated,are described in detail.Based on quantitatively analyzing the production well in the different sedimentary microfacies,development characters of different sedimentary microfacies in sublacustrine fan is summed up in the condition of extra low permeability.Differ... |
