摘要
聚合物在流经多孔介质过程中,由于表面吸附和聚合物分子间的相互作用而产生滞留,影响驱油效果。本文采用淀粉-碘化镉法测得了绥中36-1油田不同粘土矿物对疏水聚合物AP-P4的吸附量,分析了聚合物在浓度、温度发生变化时对粘土矿物吸附量的影响,并得出单位质量粘土矿物对聚合物吸附的变化规律:粘土矿物随聚合物AP-P4浓度的增加单位质量吸附量逐渐增大,随着水浴温度的增加单位质量吸附量逐渐下降。
When polymers flow in porous media,the surface adsorption and the interactions of polymer molecules will affect driving oil.Using starch-cadmium iodide method,different clay minerals had been measured on the adsorption of hydrophobic polymer in SZ36-1 oilfield and analysising of the polymerAP-P4 concentration and temperature change when the adsorption capacity of clay minerals was influenced.A unit mass of clay minerals on the variation of polymer adsorption had been gotten.With the polymer clay minerals in...
