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 improve
the 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 of
polysilicon to organic substance can improve the permeability of rock and it is a very important part of the enhanced flooding mechanism.
