【摘要】：大庆油田2003年开始对二类油层区块陆续进行注聚合物开发,截止到2013年底,大庆油田二类油层注聚层位已达到24个,含油面积197.24km2,地质储量2.4257亿吨,共有油水井8946口,累积增油2077.35万吨。虽然二类油层聚合物驱油技术逐渐趋于成熟,但在开发过程中,聚合物驱开发指标的预测一直困扰着油田技术人员。二类油层与一类油层地质特征的差异决定了它们的聚合物驱动态反映有着很大的不同,本文基于二类油层地质特征和聚合物驱的开采特点,对大庆喇嘛甸油田三个二类油层注聚区块的动态开发指标变化进行了研究与分析,得出了注入压力、注采压差、含水率、产液量等开发指标在聚合物驱过程中的变化规律,通过与主力油层开发指标变化规律的对比,研究分析适合二类油层聚合物驱开发指标的预测方法,实现了二类油层聚驱开发指标的预测,为大庆油田二类油层聚合物驱有效开采提供了理论依据和技术参考。
[Abstract]:By the end of 2013, the oil-bearing area of the second-class oil-bearing zone has reached 24, with the oil-bearing area of 197.24 km2 and the geological reserve of 2.47 billion tons, and the total oil-bearing well 8946 and the cumulative oil-increasing amount of 2077.35 million tons. Although the second-class oil-bearing polymer flooding technology is gradually mature, the prediction of the development index of polymer flooding has been a problem in the development process. The difference between the two-class oil layer and the geological characteristics of a class of oil layers determines that the dynamic reflection of the polymer flooding is very different, based on the geological characteristics of the second-class oil layer and the mining characteristics of the polymer flooding, The change of dynamic development index of three-class oil-injection block in Daqing Lamadian oil field is studied and analyzed, and the rule of development of injection pressure, pressure difference, water content, liquid yield and so on in the process of polymer flooding is obtained. Through the comparison between the development index of the main oil layer and the development index of the main oil layer, the prediction method of the development index of the second-class oil-layer polymer flooding is analyzed, and the prediction of the development index of the second-class oil-layer polymer flooding is realized, and the theoretical basis and the technical reference are provided for the effective exploitation of the second-class oil-layer polymer flooding in the Daqing oil field.
