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。采用淀粉-碘化镉法测得了绥中36-1油田不同粘土矿物对大庆LD10-1聚合物的吸附量,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:粘土矿物随大庆LD10-1聚合物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 polymer flowed in porous media,the surface adsorption and the interactions of polymer molecules would affect oil displacement.By using starch-cadmium iodide method,different clay minerals were measured on the adsorption of hydrophobic polymer in SZ36-1 Oilfield and the concentration and temperature change of polymer DaqingLD10-1 were analyzed when the adsorption capacity of clay minerals was influenced.A unit mass of clay minerals on the variation of polymer adsorption was obtained.With the increase of polymer clay minerals,the concentration of DaqingLD10-1 adsorption capacity per unit mass increases;with the increase of unit mass of water bath temperature,adsorption capacity gradually decreases.
