摘要
砂砾岩储层测井研究的难点之一是储层有效性评价。基于岩石样品的物性分析、岩石薄片、压汞实验、核磁实验和相渗实验,综合利用岩性、泥质含量、孔隙度、渗透率、束缚水饱和度和孔喉结构等参数,构建了反映储层有效性的分类综合指标,对储层有效性进行测井评价。应用到梨树断陷的双龙地区,结果表明该方法能够对研究区砂砾岩储层进行有效性评价。该方法也可以用于指导其它地区的砂砾岩储层有效性评价。
Reservoir effectiveness evaluation is one of the difficulties in glutenite reservoir evaluation by logging. According to physical property analysis,petrographic thin section,capillary pressure curve,NMR and relative permeability curve,a comprehensive index of classification reflecting reservoir effectiveness are built by comprehensively using parameters of lithology,shale content,porosity,permeability,irreducible water saturation and pore-throat structure. This method was applied to glutenite reservoirs of Shuanglong area in Lishu Fault Depression. The results indicated that this method is appropriate to evaluate the glutenite reservoir effectiveness of the research area and also provides a guide for the glutenite reservoir effectiveness in other areas.
