摘要/Abstract

摘要： 为明确渤海湾盆地莱州湾凹陷垦利L油田古近系沙三上段储层物性特征及影响因素，综合利用铸体薄片、扫描电镜、X衍射、孔渗测试、地层测试等多种分析测试手段，结合区域构造背景、沉积体系等相关研究成果，探讨了沙三上段储层物性控制因素，并在油田注水开发中开展了应用。研究结果表明：沙三上段储层平均孔隙度为28.9%，平均渗透率为762.7×10^-3 μm²，属于高孔高渗储层，储集空间以原生粒间孔为主，可见次生粒间孔和铸模孔，微裂缝发育；微裂缝平均宽度为180 μm，微裂缝的存在提供了高效渗流通道，使地层孔渗测试结果明显优于岩心测试数据；优质储层的分布主要受体系域、断裂活动和埋藏作用的影响，水进体系域厚层净砂岩是形成优质储层的物质基础，微裂缝发育提高了渗流能力，快速埋藏减缓了储层孔隙水的排出和储层物性的降低。根据优质储层发育特征及生产动态资料，优化水井分层配注，降低平面及纵向上水驱不均，实现了油田均衡驱替。

Abstract: The physical characteristics and genesis of the upper part of the 3rd member of Eocene Shahejie Formation (E₂s₃^u) in Kenli L oilfield of Laizhou Bay sag in Bohai Bay basin were clarified by using a variety of analyses and testing methods, such as casting thin sections, SEM, X diffraction, pore permeability test and drilling test, combined with the related research results of regional tectonic setting and sedimentary system, the physical properties control factors of E₂s₃^u were discussed, and applied in oilfield water injection development. The results show that:the reservoir of E₂s₃^u with the average porosity of 28.9% and the average permeability of 762.7×10^-3μm² belongs to "high porosity-permeability" reservoir,the reservoir space is mainly primary intergranular pores with secondary intergranular pores, mold holes, and micro-fractures; the average width of the micro-fractures is 180 μm, the existence of the micro-fractures provided a highly efficient seepage channels, which makes drilling test pore permeability is obviously better than that through core test. The physical properties of high quality reservoirs are mainly affected by system tract, fault activity and burial, the thick net sandstone under transgressive system tract is the material basis of forming high-quality reservoirs; the developed micro-fractures improved seepage capacity; rapid burial slowed the drainage of reservoir pore water and the decline of reservoir physical properties. Based on high-quality reservoir development characteristics and production dynamic data, optimizing layered allocation of water wells, reducing uneven water flooding in the horizontal and vertical directions, and then Kenli L oilfield achieved balanced displacement.

Key words: high quality reservoir, micro-fracture, control factors, E₂s₃^u, Kenli L oilfield
