摘　　要：针对二连油田A区低孔隙度低渗透率储层解释结论低而压裂试油高产的现象,经过岩石孔隙分析,对于与压裂后产液量有关的参数进行精选、简化,最终确定了由次生孔隙度、孔隙结构系数、总孔隙度等重要储层参数进行统计分析及低孔隙度低渗透率储层产能预测,归纳出适合A区的压裂后产能预测方程;首次对该类储层进行储层压裂后产液量预测,在二连油田应用中见到了较好的效果。In block A in Erlian oilfield the interpretation result indicates that some reservoirs with low porosity and low permeability have poor oil ＆ gas reserve, but have high production capability after being fractured. Based on analyzing pore structures and we come to the conclusion that secondary porosity plays an important part in the productivity forecast of this kind of reservoir. Three important parameters such as secondary porosity, pore structure coefficient and total porosity are used to forecast the reservoir productivity. The obtained forecast equation is adaptable to productivity forecast of the reservoir with low porosity and low permeability.
