摘　　要：储层微型构造是在总的油田构造背景上 ,储层顶底面的微细起伏变化所显示的小构造。应用水动力学方法分析了油田注水开发时在储层微型构造中形成剩余油的原因。指出了储层微型构造存留剩余油是一种水动力圈闭 ,完全可以引用哈伯特势能理论来解释和判断 ,分析认为 ,在储层微型构造中油、水相势的方向和大小不同。当油相势梯度指向储层微型构造的内部时 ,便形成了剩余油。同时也给出了如何动用这些剩余油的一些相关认识。Reservior micro structure is a small subclass on the oilfield structure because of fine distinction of the layers depth. This paper analyzes the cause for residul oil stagnated in the reservior micro stucture that used the hydrodynamic method then oilfield injection water exploration. It pointed out that residual oil stagnated in the reservior micro structure is a hydrodynamic trip, we may use potential energy theory of Hubbert for exploration and jugement. The result analyzed has indicated that residual oil forms when potential energy gradient of oil phase point to inside of reservior micro structure because the direction of potential energy gradient is different from oil and water. The knowledge of exploiting this kind of residul oil is given in the paper also.
