中文摘要：
葡北油田已进入高含水、高采出程度的开发阶段,受到砂体展布特征的影响,剩余油分布复杂而零散,因此,在剩余油饱和度富集区寻找高效井及对控制高效井的因素进行分析与研究是挖潜这些剩余油的有效途径。通过研究葡北油田已有高效井的形成条件及分布特点,利用已定量的各类储层参数和开发参数,建立了高效井成因模式。经实际验证,方法可行、可靠,为下一步剩余油挖潜提供技术及理论支持。
英文摘要：
It came into the development stage of the high water cut and high degree of reserve recovery in Pu-bei oilfield. The distribution of remaining oil was complicate and scattered , which was affected through-going characteristic of sand body, as a result, it was an active method of tap the latent power remaining oil that looking for high efficient wells and controlling factors of high efficient wells were studied and analyzed in concentration area of remainder oil saturation. Through studying the conditions for the formation and distributed trait Of high efficient wells in Pu -bei oil.field, and making use of all sorts of reservoir parameters and operational parameters which were applied, the genetic model of high efficient wells was established. The method is feasible and reliable through practical verification. It provides technique and theory support for further tapping the latent power remaining oil.
