Study on The Percentage of Movable Fluid Parameters in Hailar Low-Permeability Reservoir

The explanation of the concept of percentage of movable fluid, test principle, applicatior in reservoir evaluation in Hailar low-permeability reservoir was finished in this paper. The paper also analyzed the relationships among percentage of movable fluid, permeability, and displacement efficiency. By means of the measurement and analysis on the core of the percentage of movable fluid in Hailar low-permeability reservoir, The results showed that percentage of movable fluid in an important parameter in reservoir evaluation, which can be used in prediction of the effective it low-permeability reservoir. And there is some correlation between percentage of movable fluid an permeability in same reservoir. Compared with the peripheral low-permeable oil field in Daqing and Jilin, the percentage of movable fluid of Hailar low-permeability reservoir is equivalent with Yushulin low-permeable oil field in Daqing, lower than Xili low-permeable oil field in Jilin, bigger than Zhaoyuan low-permeable oil field in Daqin.
