D" from experiment, one can construct the dependence Q( We) for the given rock
based on (10.30).
The relations Q/Qo(we/(E"Qo)), 1/Je(we/(E"Qo)) = (Q- Qo)E" /we for some
media are presented in fig. 65. The function 1/Je defines the additional volume
of the solution obtained per unit energy consumption rate. Those curves in fig.
65 marked with index 1 correspond to the case of the linear dependence K(T)
in the whole temperature range (Tc = oo). The results of the calculations with
parameters F" = 10, L" = 0.1; 0.2; 0.3, are denoted by indices 2- 4, respectively,
and the results of the calculations with F" = 40 and the same L", by indices 5 -
7.
It can be seen in fig. 65, b, that the function 1/Je has a maximum for certain
values of L" and F". It corresponds to the minimal energy consumption needed to
obtain additional recovered volumes of fluid, and therefore corresponds to the opti-
mal electric treatment regime. Take w; / ( E" Q 0 ) and ¢; as the point of maximum
for the function 1/Je and its value 1/Je(we) there. In fig. 66, a, the L" dependencies
