本文对濮城油田南区沙二上 2 +3储层的非均质性从四个方面作了系统研究 ,本区储层储集空间以粒间孔 ,粒内容蚀孔为主。孔吼组合以中孔隙 ,中细吼道为主。层内非均质性较强。层内夹层多 ,层间渗透非均质性较弱 ,层间隔层分布较为稳定 ,在油田开发生产中反映以层内矛盾为主 ,所以研究层内非均质特征及剩余油分布是今后工作的重点 In this paper, we systematically studied the heterogeneity of 2 + 3 reservoir in the Upper Sha 2 Upper Pucheng Oilfield from four aspects. The main reservoirs in this area are intergranular pores and intragranular pores. Hole roar combination in the pore, in the main roar. In-layer heterogeneity is strong. There are many interlayers in the layers, and the inter-layer interpenetrating heterogeneity is weak, and the interbedded layers are relatively stable. In the development and production of the oilfield, the intra-layer conflicts are the major ones. Therefore, the heterogeneity of the interbedded layers and the remaining oil distribution are the future work the key of
