15) calculate not in the same time ti (i=1,2,3 ... n, n are natural number) in visual vertical flat plate sandpack column each layer of sand inject water volume ratio:
Ground floor (ti �� t)��ti moment injects water volume and is:
V1=(S1 (t=ti) S2 (t=ti-�� t)) �� h �� �� 1 (I);
The second layer (ti �� t)��ti moment injects water volume and is:
V2=(S ' 1 (t=ti) S ' 2 (t=ti-�� t)) �� h �� �� 2 (II);
Third layer (ti �� t)��ti moment injects water volume and is:
V3=(S " 1 (t=ti) S " 2 (t=ti-�� t)) �� h �� �� 3 (III);
Then, the volume ratio of above-mentioned three layers layer of sand injection water is respectively as follows:
Ground floor layer of sand injects the volume ratio of water
Second layer layer of sand injects the volume ratio of water
Third layer layer of sand injects the volume ratio of water
In formula (I)-(VI), the injection water volume of V1, V2, V3 respectively first, second and third layer of layer of sand; The water suction ratio value of K1, K2, K3 respectively first, second and third layer of layer of sand; H is the thickness in flat board back-up sand chamber, cm; S1, S ' 1, S " 1 respectively first, second and third layer of layer of sand inject fluid sweep area, cm in the ti moment2; S2, S ' 2, S " 2 be one, two, three layers ti �� t inject fluid sweep area, cm2; The porosity of �� 1, �� 2, �� 3 respectively first, second and third layer of layer of sand;
16) volume ratio standard as each layer layer of sand water absorbing capacity of evaluation of water is injected using each layer layer of sand, draw dynamic intake profile curve, the abscissa of its coordinate system residing for dynamic intake profile curve is the volume ratio that layer of sand injects water, and vertical coordinate is first, second and third layer of layer of sand.
9. the device of kinetic measurement intake profile draws the application process of dynamic intake profile curve as claimed in claim 8, it is characterized in that, in step 2) in, utilize single tube back-up sand rock core to measure the porosity of three layers layer of sand respectively, measure the permeability of three layers layer of sand simultaneously.
