P. 53

If the task is solved for Q(t) ≠ const, then use the method
          of superposition.
                  The  method  of  superposition  -  a  way  of  solving
          hydrodynamic tasks when their general solution defined as the sum
          of the solutions. In other words, changing the pressure at any point
          of the layer is determined by the direct summation of depression
          caused by the work of single wells.
                  In  the  event  that  the  deposit  on  working  well  with
          different flowrates (Q), and the need to find a change of pressure
          in any point of the layer (p. M), then come true (Fig. 3.12).



































                  - production well;    - injection well.
