| 摘 要： | 延长油田长6油藏为典型特低渗岩性油藏,油藏主要受陆相三角洲沉积体系控制,储层物性差、产量低、天然能量匮乏,现阶段科学合理的注水开发是延长油田持续发展的关键举措,但由于储层层内和层间非均质性强,若整个油层组笼统注采开发,则采出程度低,经济效益差.笔者综合了岩心、测井曲线、相关实验分析数据及地质录井等基础地质资料,结合区域地质特征,通过细分开发层系、开展精细地层对比、小层沉积微相及砂体展布规律研究,为优化注水开发方案和选用先进注采配套工艺技术措施提供了比笼统注采更为详尽的地质依据.

| Abstract: | Oil-pool of Yanchang formation Chang-6 is the typical lithologic oil-pool, it mainly is controlled delta sedimentary system of continental facies. Reservoir physical property is bad, and the output is low, and natural energy is deficient, now , science reasonable water injection is essential action of Yanchang oilfield continue development, if the whole oil reservoir set generally develop, the producing degree and the economic benefit is poor, because the anisotropism of reservoir is high. The author synthesis the basic geologic data on core, well-logging , experiment and geologic borehole log and so on, and union region geologic characteristic , study on sedimentary microfacies of subzone , accurate stratum contrast, and the distribution rule of the sandstone, by accurate division development reservoir groups, which provides geologic basis better than general injection-production technology to optimize the injection-production development scheme and select advanced matching technology. |
