摘    要:探讨了聚硅材料对有机物堵塞的溶解作用,对聚硅材料的性质做局部分析。由于聚硅材料是分散在柴油中,所以实验过程中需要用对比方法排除柴油的干扰。静态和动态溶解实验可以考察聚硅悬浮液对有机物的溶解速度,在此采用溶解比值Kr作为定量分析的参数。经证实聚硅材料促进了有机物的溶解速度。动态实验显示的溶解速度快与静态实验,但是溶解比值与静态结果接近。玻璃模型的微观观察可以直观地证实,聚硅悬浮液的溶解作用优于柴油。模拟油层条件的宏观驱替实验则更明显地证明了聚硅悬浮液对有机物的溶解可以提高岩石的渗透率,是增注机理的一个重要组成部分

关 键 词:聚硅悬浮液  有机物  堵塞  溶解

Abstract:Because the polysilicon is dissolved in diesel oil and be-comes a dispersive system,it is necessary to remove the disturb by diesel oil using contrastive methods. Static and dynamic ex-periments can measure the dissolving rate of organic substance.The ratio of solution mass, K,,which is used as a parameter for quantify analysis. The result shows that polysilicon can improvethe dissolving rate. In dynamic experiments,it is obvious that the dissolving rate by polysilicon is faster than diesel oil. But solotion ratio is similar with the static state. The microcosmic obnervation through glass model can prove directly that the solution of polysiliron is better than diesel oil. The experiments consider-ing the reservoir environment have proved that the solution ofpolysilicon to organic substance can improve the permeability of rock and it is a very important part of the enhanced flooding mechanism.
Keywords:polisilicon suspending liquid  organic sub-stance  blocking  solution
