          where α - coefficient to increase filtration resistance. It is defined
          by the formula (3.22).
                  External filtration resistance for region 0-F is defined by
          the formula (at the region   O-F at the formula we substitute the
          coefficient of dynamic viscosity oil)

                  If the task is solved for the case when Q = const, then the
          equation  (3.22)  wondering  intermediate  position  WOC  (l 0-F)
          determine the bottom-hole pressure depending on the position of
          the WOC.
                  If the task is solved for the case when   P bh = const, the
          same way the series is calculated the flow rate of wells depending
          on the position of the WOC.
                   Dynamic basic indicators of development depending on
          the time under water drive are shown in Fig. 3.10.
