摘要/Abstract

摘要： 大庆油田二类油层相比一类油层具有渗透率低、非均质性强、砂体发育较差的特点，为了更大程度上发挥聚合物驱油技术在二类油层上的开发效果，基于聚合物驱油墙聚并理论和流度控制理论，提出了变流度聚合物体系的梯次降黏、恒压提速的注入方式，即采用先高黏低速调堵高渗层、后降黏提速启动中低渗层的段塞式注入方式。该方式与交替注入对比实验结果和矿场应用效果表明：变流度聚合物梯次降黏注入的驱替前缘压力梯度大，可聚并形成高饱和度油墙，大幅度降低含水率，明显增加高渗透层流动阻力，后续低黏段塞以提速注入的方式依次匹配进入中低渗透层，明显扩大了中低渗透层的波及体积，改善了高、中、低渗层流度差异，在降低注聚成本的基础上，进一步提高了聚合物驱在非均质油藏的采收率。在梯次注入基础上提出的变流度聚合物驱新设计思路，指出了变流度聚合物驱设计参数关键在驱替段塞的数量和聚合物体系同油层的匹配关系。

Abstract: Compared to the Class-Ⅰ oil layers in Daqing oilfield, Class-Ⅱ oil layers possess lower permeability, stronger heterogeneity and poorer sand-body development. To enhance the development effects of polymer flooding technology better in the Class-Ⅱ oil layers, the theory of oil bank forming and mobility control were adopted to instruct polymer injection pattern, and the echelon visbreaking injection with multiply-mobility polymer solutions was proposed. It was described as high-viscosity slug being injected with low rate and subsequent low-viscosity slugs being injected with higher injection rate. The physical experiment compared with alternative-injection pattern reveal that pressure gradient of displacement front with multiply-mobility polymer solutions could be considerable and highly concentrated oil bank could be formed, which substantially reduces total water cut and obviously improves the flow resistance of high permeability layer. Moreover, subsequent low-viscosity slugs injected with higher rate could evidently boost the absorption amount of mid and low permeability layers, which shrinks the mobility difference among sorts of permeability layers and amplifies the swept volume. Eventually, it could further enhances oil recovery under the condition of reducing polymer dosage cost. Further, the new design idea of adjustable-mobility polymer flooding was proposed on the basis of echelon injection. The conclusion is that the most sensitive parameters are numbers of polymer slugs and the relationships between polymer solutions and oil layers.
