摘　　要：薄互层稠油油藏蒸汽吞吐后剩余油预测是稠油油藏挖潜的基础。采用单井采出程度、波及体积系数和驱油效率三者的关系,计算井间汽窜和未汽窜单井的泄油半径,据二者泄油半径内面积之差确定汽窜带的宽度,从而达到预测吞吐后剩余油分布的目的。Prediction of remaining Oil in viscous crude Oil reservoir with thin interbeds is foundation of taping potentials. This paper through using relationship of degree of reseave recovery, sweep volume efficiency and displacement efficiency to Single wells calculated the drainage radius and drainage area under conditions of steamchanneling and no steamchanneling. According to difference of two area determined width of steamchanneling zone, thus attaining the purpose for predicting remaining Oil.
