摘　　要：用动态分析法，对已整体报废、蒸汽吞吐后采收率小于２０％的河南油区井楼油田零区剩余油分布进行了研究，认为蒸汽波及半径平均为３１．２ｍ，汽窜通道宽度平均为１５ｍ。利用井网加密，进行二次蒸汽吞吐，可使其采出程度提高１５％。Through dynamic analysis, this paper studies remaining oil distribution of block zero,Jinglou oil field, Henan oil province, which has been completely abandoned and whose recovery factor is less than 20% after steam soak. It is believed that the average steam swept radius is 31. 2 m,the average width of steam channeling is 15 m. The recovery percent of reserves can be enhanced 15 % by infill pattern and secondary steam soak.

关 键 词：蒸汽吞吐 剩余油分布 泄油半径 油田 提高采收率
