The analysis result shows that the remaining oil of this area is characterized as: Remaining oil is mainly distributed in thin tabulated beds and untabulated beds with low permeability. Remaining oil scatters widely. Complexity exists in the contact between remaining oil and water flooded layers and zones. Vertically, the remaining oil layers in adjusting area alternates with water breakthrough layers, between them the barrier beds is thin. Horizontally, because of the plane heterogeneity, the relatively good intervals are flooded, so that the remaining oil only exists in margin oil layer owing to faultiness of injection-production; remaining oil is enclosed by waterflooded zone, therefore, it is so complex relationships between remaining oil and waterflooded layers and zones that high requirements are made in the choice of completion optimization.

通过研究分析，研究区二类油层剩余油具有以下特点：(1)剩余油以表内薄差层和表外层为主，渗透能力低；(2)剩余油比较零散；(3)剩余油与水淹层和水淹带的接触具有复杂性；调整区剩余油从纵向上看，剩余油层与见水层相间分布，隔层小；从平面上看，由于油层平面的非均质性，相对较好部位已水淹，只在油层的边边角角部位由于注采不完善等因素存在剩余油，剩余油被水淹带包围，所以目前剩余油与水淹层和水淹带的接触相当复杂，这对完井方式的选择提出更高的要求。
