摘　　要：为解决李堡油田堡1块开采过程中注采对应关系不好的问题,运用储层构型分析法,将堡1块储层划分为五级层次:段、砂层组、小层、单砂体、成因砂体。运用标志层划分段,用旋回特征划分砂层组,运用较稳定泥岩隔层与岩性-厚度法划分小层,依据不同级别的沉积间断面划分单砂体与成因砂体,最终完成堡1块成因砂体的划分与对比。结果表明,将储层划分与对比精细到了单砂体与成因砂体,对研究区储层非均质性研究及注采对应关系分析有重要意义。To solve the problem of poor corresponding relation in the development of Block Bao 1 in Libao Oilfield,a method of reservoir types was used to divide the reservoirs in Block Bao 1 into 5 stages including interval,sand group,subzone,single sandbody and genetic sandbody.By means of marking zone division,the cyclic characters were used for sandbody division,a method of stable mudstone barrier and lithology-thickness was used for subzone division.Based on different sedimentary discontinuity planes,single and genetic sandbodies were divided for eventual sandbody classification and comparison .The result indicates that it is of great significance for studying heterogeneity and the corresponding relation of injection and production.
