The article presents the dependences, permitting to calculate the fluid level in the annulus of the sucker rod pump (SRP) at step changing of the beam-pumping unit actions number and to simulate the SRP dynamometer cards . It is shown that the dynamometer cards of SRP measured during normal operation and in the poor inflow conditions enable to assess the fluid level in the annulus, a maximum fluid influx into the borehole and parameters of the reservoir.
