本文阐述了油田开发用水溶性高分子材料的结构特征,着重探讨了储集层孔隙介质对高分子材料的静态与动态吸附(捕集)作用,以及不可及孔隙体积、滞留作用与地层伤害的关系。还进一步讨论了高分子材料溶液粘度对降低流动阻力系数、增加波及系数、提高原油采收率等的影响。
This paper describes the structural characteristics of water-soluble polymer materials used in oilfield development, and focuses on the static and dynamic adsorption (capture) effect of pore media on polymer materials and the relationship between the inaccessible pore volume and retention and formation damage . The effects of solution viscosity of polymer solution on the reduction of flow resistance coefficient, increase of wave propagation coefficient and oil recovery were also discussed.
