【 摘 要 】

In the Daqing Oilfield, the oil flooding of one type of oil layer was transferred to the subsequent water flooding, and the third oil recovery object gradually transferred to the thinner and worse two or three oil layers. Although the three types of oil layers are thinner and have lower physical properties, their reserves are large, reaching 1.86 billion tons, accounting for 44.6% of the total reserves of the Lamadian Oilfield, Sarto Oilfield, Xingshugang Oilfield. It is the sustainable development potential of the oil fields after the second type of oil layers. Aiming at the characteristics of three types of oil layers, such as thin oil layer, poor physical property and scattered distribution, it is determined that it is suitable for polymer flooding to develop reservoir objects and their utilization limits. It is one of the difficult problems for the three types of oil layers to further improve oil recovery.
