摘要
通过钻井岩心、薄片、扫描电镜等资料,对红山嘴油田红浅1井区砂砾岩稠油储层特征及其主控因素进行详细研究。结果表明:该研究区砂砾岩稠油储层主要以粗粒度的砂砾岩为主,发育的孔隙类型主要为原生粒间孔隙,为中高孔、中高渗的孔隙式储层;宏观上,沉积作用控制储层的平面分布,微观上,成岩作用影响储层的纵向内部结构;由储层的含油性显示发现,扇三角洲沉积当中受牵引流改造的砂体,若其钙质胶结作用较弱并伴有局部溶蚀、微裂缝作用,其含油性明显。加强沉积相认识及成岩作用的研究,对后期开发部署井位的优选及开发技术适用性研究都具有一定积极作用。
By using drilling cores,thin slices,SEM and other available data,features and major controlling factors of glutinite heavy oil reservoirs in the HQ- 1 Well Block of the Hongshanzui Oilfield were studied. The results show that such reservoirs are dominated by coarse glutinite,with primary intergranular pores,proving these reservoirs as porous reservoirs with medium to high porosity and permeability. Macroscopically,planar distribution of reservoirs is controlled by sedimentation. Microscopically,lithification may affect internal structure of these reservoirs vertically. Studies on oil potential of the reservoir show that sandstone reconstructed due to drag flows in fan delta sediments may contain favorable oil potential if it has weak calcareous cementation associated with regional dissolution and minor fractures. More researches on sedimentary facies and lithification processes may play an important role in deployment of development wells and determination of applicability of production processes in later stages.
