摘　　要：目前萨南油田南四区适合聚合物驱油的一类油层剩余油储量逐年减少,聚合物驱产量不断递减,该区二类油层不发育,三类油层大面积发育,因此三类油层注聚是实现产量接替的有效途径。结合萨南油田南四区东部三类油层聚合物驱现场试验进行了井壁取心和分析。通过井壁取心资料研究了剩余油分布特征,为该区剩余油分布研究提供了新的评价手段。At present, the reserves of the remaining oil of Class 1 reservoirs which is suitable for polymer flooding in Nan IV area in Sanan Oilfield decreases year by year. Polymer flooded production also decreases. Class 2 reservoirs do not develop much in this area, while Class 3 reservoirs develop in a large area. So polymer flooding in Class 3 reservoirs is an effective way for production replacement. This paper performs sidewall coring and analysis on the pilot test of polymer flooding in Class 3 reservoirs in eastern Nan IV area in Sanan Oilfield, and studies the remaining oil distribution using sidewall coring data, providing a new method for remaining oil distribution study of this area.
