摘要
安塞油田属于典型的特低渗透油藏，王窑是开发最早的区块，已进入中后期开发阶段，含水高，采出程度高，为提高原油采收率，先后开展NOD分子驱、化学膜驱、聚合物驱机理及影响因素的研究和室内模拟实验．并进行了矿场试验，取得了一定的认识及成果。
Ansai oilfield is typical of ultra-low permeability reservoir, Wang kiln is the development of the first block has entered the mid-and late stages of development, high water, picking out a high degree in order to enhance oil recovely, has to carry out molecular drive NOD , chemical fihn flooding, polymer flooding mechanism and influence factors and indoor simulation experiments, and conducted pilot test achieved a certain degree of knowledge and results.
