摘要
为了研究聚合物KYPAM-6A溶液在油藏条件下的黏弹性情况,根据SY5523-2000配置聚合物溶液进行实验,研究质量浓度、矿化度、角频率的变化对溶液损耗模量、储存模量的影响.结果表明:①随着质量浓度的增大、矿化度的减小、频率的升高,聚合物溶液的储存模量、损耗模量均有不同程度的升高.②聚合物溶液在低频率下,以黏性流动为主,在中高频率下,以弹性流动为主.③随质量浓度的升高、矿化度的降低,聚合物溶液黏弹主导转化点频率,即储存模量、损耗模量交点频率随之升高.
In order to study the viscoelasticity of polymer KYPAM-6A solution under the condition of reservoir,the polymer solution is prepared according to the standard of SY5523-2000.The effects of the mass concentration and the salinity and the shear angular frequency of the polymer solution on its loss modulus and storage modulus are studied.It is shown that,(1) the loss modulus and the storage modulus will increase in different degree with the increase of the mass concentration and the shear angular frequency and the decrease of the salinity;(2) the viscous flow of the polymer solution dominates at low shear angular frequency and the elastic flow of it dominates at medium-high shear angular frequency;(3) the shear angular frequency at which the polymer solution produces the conversion between viscous flow and elastic flow will increase with the increase of the mass concentration and the decrease of the salinity.
