朝阳沟油田朝5-朝45区块剩余油分布特征

朝5－朝45区块油层自下而上随着沉积环境的变迁，砂体发育规模逐渐减小，单一河道砂体发育数目增多，砂体平面分布越来越复杂，导致油层水淹状况和动用程度极不均匀，造成了剩余油分布分散而复杂，应用密井网测井资料开展储层精细地质描述，依据注，采井网对单砂体的控制状况和加密井水淹层解释及开发动态资料，具体研究油层剩余油富集区的分布状况，依据该研究成果，在区块综合调整过程中，取得了较好的措施增油效果。

The Study of Distribution Characteristic of the Remaining Oil in Chao5-Chao45 of Chaoyanggou Oilfield

With the changing of the deposite environment of the reservoir from down to up in Chao5 Chao45,the scale of sand bodies get smaller and smaller,the numbers of the single sand body of river channel get more and more,and plane distribution of sand bodies get more and more complicated,leading to the heterogeneity of the waterflooded and employed degrees,and the dispersed and complicated distribution of remaining oil.researching of refined geology reservoir by the log data of the dense well pattern,researching the distribution of remaining oil of reservoir by means of the single sand body being controlled by the well pattern and the analysis of waterflooded reservoir of the dense well,and development data of the oilfield.According to the result of refined geology, the better effect of increasing oil production has been gotten.
