DEVELOPMENT AND APPLICATION OF PERMANENT DOWNHOLE GAUGE IN OIL PRODUCTION CONTROL SYSTEM

Relevance of the research is in obtaining reliable measured technological parameters (as a minimum, pressure and density of the produced products) in the well obtained in real time for managing the quality of oil producing well and increasing the efficiency of its operation. The aim of the research is to develop a permanent downhole gauge for measuring pressure at the pump inlet and discharge, inside the tubing and annulus of an oil producing well; compile a mathematical model for obtaining necessary technological parameters to solve the main problems in oil production; apply a permanent downhole gauge in the proposed oil production control system. Object of the research is oil producing well. Methods: modeling and evaluation of the proposed oil production control system using the developed permanent downhole gauge for measuring the pressure at several control points of the oil production wells in the program Matlab/Simulink. Results. The authors have developed the permanent downhole gauge for measuring pressure at the pump inlet and discharge, inside the tubing and annulus of the well. The paper demonstrates its design and the mathematical model for obtaining the necessary technological parameters to solve the main tasks in oil production. The authors proposed the control system using the developed gauge, set the task of creating an effective system for managing oil production and solved it. Conclusions. A positive result was obtained when simulating oil production control system using the developed downhole gauge for measuring pressure at several control points in an oil producing well using the Matlab/Simulink program. The implementation of the developed permanent downhole gauge in the proposed system for controlling oil production ensures the accuracy and speed of switching the well to the stationary mode of operation, its stabilization and increase in the flow rate.
