利用岩电参数计算聚合物驱相对渗透率
A new method for calculating relative permeability of polymer flooding based on core-electrical parameters
摘要
Abstract
The precision of relative permeability data is crucial for the study of polymer flooding process.The steady-state and unsteady-state method are mostly used methods for measuring the relative permeability during polymer flooding,in which the viscosity of polymer solutions should be known.For most polymer solutions,their viscosity will vary with the shear rate or flow rate during the flooding process.Many polymer viscosity models have been proposed to correct the viscosity effect in the determination of the relative permeability,while different models can lead to different results and have limitations for field application.In this study,a new method for determining the relative permeability of polymer flooding was introduced based on the resistivity data of rocks saturated with polymer solutions.The new method was verified by the experimental data,and was compared with the traditional methods and the correction methods.The results show that the relative permeability of the polymer phase obtained by the new method is precise and reasonable,which can avoid the problem that the relative permeability might be over-estimated when using the traditional methods.关键词
