以孤岛西区复合驱体系为研究对象 ,借助流动实验和HPLC分析方法 ,对胜利油田孤岛西区三元复合驱体系中各有效组分 (Na2 CO3+HPAM +PS +BES)在地层油砂上的吸附情况及色谱分离效应进行了研究。实验表明 ,所有有效组分在地下运移过程中未发生显著的分离 ,不会对驱油配方中各组分的协同效应、驱油体系的整体性能造成明显影响。文章不仅对孤岛西区复合驱现场 ,也必将为同类驱油技术的矿场实施提供有益的理论和试验依据。
Taking Gudao Western composite flooding system as the research object, the adsorption of active components (Na2 CO3 + HPAM + PS + BES) on the stratigraphic oil sand in the ternary compound flooding system of the West Island of Shengli Oilfield was studied by flow test and HPLC analysis And chromatographic separation effects were studied. Experiments show that there is no significant separation of all effective components during underground transport, and no significant effect on the synergistic effect of the components in the flooding formulation and the overall performance of the flooding system. The article not only provides a useful theoretical and experimental basis for the implementation of the compound drive in West Island of Gudao, but also for the implementation of similar oil recovery technologies.
