塔河油田底水砂岩油藏属辫状河平原相沉积,以"相控砂体"理论为指导,结合夹层展布及其与轨迹在微相中不同的位置关系,开展河道与心滩砂体连通性研究,并利用数值模拟手段,明确砂体叠置结构特征对水驱方式和剩余油分布的影响,有效指导高含水期剩余油的挖潜工作。

The sandstone reservoirs with bottom water in the Tahe Oil Field belong to plains of braided river facies. We studied the connectivity between channel and channel bar sand body based on the "sedimentary facies controlled sand body" theory and combined with intercalation distribution and its relationship with micro facies. By using numerical simulation, we analyzed the influence of sand body superimposition on water flooding mode and remaining oil distribution, which could guide remaining oil potential tapping during high water-cut stages.
