Abstract

The aim of the study is to obtain reliable values of bottomhole pressure calculation method in oil wells of PJSC «Tatneft» due to technical difficulties emerged when performing deep measurements of producing wells at the Romashkino oil field.

We have performed calculations of bottomhole pressure in wells according to Hasan — Kabir method and the RD 153-39.0-920-15 method. The comparison of the obtained values revealed that the average relative error of Hasan — Kabir method is 5,33 % (not more than 10 %), in contrast to the RD method.

Also, we have created the model of the process control system of oil production in the program MATLAB/Simulink. This program includes the algorithm of regulation the liquid rate. In modeling the control system, a transient process is observed, in which the value of the liquid rate increases and stabilizes. Thus, the application of Hasan — Kabir method in the proposed process control system of oil production is possible in all wells at the Romashkino oil field.
