Making an analogy between the equations (3.1) and (3.2)
we see that the analogy between hydrodynamic and electrical
parameters is shown in the following:
change in voltage between nodes electricity grid u
similar to the pressure, that is
u  Р;
current, which flows between the nodes of the grid is
proportional to the amount of fluid that flows between the regions
of the reservoir, that is
ІQ.
Finally, by analogy R1/k 0. This value is called the
filtration resistance.
The principle (EHDA) is based on generalization electric
current laws and fluid flow in porous media. The principle is based
on the community mathematical description of the processes
occurring in the reservoir during the filtration process of fluids
flow of electric current.
Based on the method (EHDA) professor Y. Borisov has
developed a method of assembling the hydrodynamic equations for
calculation processes of oil fields in the certain placement of wells.
Using this method, you can easily make a determination equation
flowrates and bottom-hole pressures for any of the options strip or
circular rows of wells.

3.1.3 Hydrodynamic calculations flowrates and
bottom-hole pressures, and also validities of water-oil
displacement without phase permeabilities

The task is solved for two cases, when specified bottom-
hole pressures and need to find flowrates or vice versa when
specified flowrates, and the need to find bottom-hole pressures.
Chance is another task statement when some asked find bottom-
hole pressures and flow rates in other rows of wells.
