摘　　要：针对复杂小断块砂岩油藏取心资料较少、测井评价困难的问题,提出了建立有效孔隙度、原始含油饱和度的理论测井解释图版。该方法以苏北盆地区域资料为基础,统计有效孔隙度、含油饱和度与岩心骨架成份、粒度、渗透率、油藏埋深等之间的关系,利用上述关系建立了有效孔隙度、原始含油饱和度的理论测井解释图版,并在未参与上述研究的苏北盆地A油田进行验证,取得了良好的应用效果。该方法对小断块油田勘探具有较大的指导意义。In consideration of the problems of less coring data and difficulty of logging evaluation in complex and small fault block sandstone reservoirs,it was proposed that a chart board was established for theoretical interpretation of effective porosity and original oil saturation.Based on the regional data of Subei Basin,statistics was made on the relationship among the effective porosity,oil saturation,components of core framework,grain grade,permeability and reservoir buried depth.It is used for establishing a chart board for a theoretical interpretation of effective porosity and original oil saturation,and it is proven in A Oilfield of Subei Basin(which is not involved in the above study),and good result is obtained in application.It is of great significance for guiding the exploration of small fault block oilfields.
