| Abstract: | Tests on core PI value with multifunction device evaluating production chemical agent are described principally in this paper.The authors study the relationship between core PI value and core permeability, injecting fluid flow rate,core area value of cross section,the relation-ship between parallel cores recombination PI value and one core PI value and volume coefficient of some general profile control agents.Finally an application example of PI decision technology based on percolation mechanics theory and PI core test is given. |
