摘要(Abstract):

为了计算交替注入聚合物溶液对残余油的作用力,进一步从水动力学角度探索交替注入聚合物溶液提高原油采收率的机理,运用上随体Maxwell本构方程建立了具有黏弹性的聚合物溶液在微孔道中的流动方程,运用数值方法对流场进行了求解,获得了驱替液作用在残余油膜上的应力分布,分析了聚合物溶液的黏弹性和压力梯度与水平驱替力这一表征驱替效果的关系,最终分析了交替注入聚合物段塞可以提高原油采收率的机理。
In order to calculate the force of alternately injecting polymer solution on the residual oil and further explore the mechanism of the solution to enhance oil recovery from the viewpoint of the hydrodynamics,the flowing equation of the viscoelastic polymer solution in the micro pores and channels is established by means of upper-convected Maxwell constitutive equations,the solutions are seeked and solved by the numerical method for the flow field,and then the stress distribution of the residual oil on the oil film is obtained for the displacing solution action,the relations of characterizing displaced effects between the viscoelasticity and pressure gradient of the polymer solution and the horizontal flooding force are analyzed,finally the EOR mechanism of alternating injected polymer slug is also figured out.
