针对双河油田二类储量聚合物驱单元递减期制约聚驱效果的“四类井层”:即聚窜井层、封堵井层、见效差井层、堵塞井层,根据递减期的动态变化特征,集成应用动态调整技术,开展综合治理,可减缓后期递减,改善聚驱开发效果,对同类单元的开发可提供经验借鉴。 According to the double-depleted polymer flooding units in the Shuanghe Oilfield, the “four types of well layers” are controlled by the depletion period: the poly-channeling wells, the plugging wells, the poor effective wells and the plugging wells. According to the decreasing period Dynamic integration of the integrated application of dynamic adjustment technology to carry out comprehensive management, can reduce post-decline, improve the development of poly flooding effect, the development of similar units can provide lessons learned.
