Abstract

Система управления газлифтной добычей из нефтяной скважины содержит динамически регулируемый дроссель (1) для регулирования потока сырой нефти из эксплуатационной трубы (2) скважины. Дроссель (1) управляется модулем управления, содержащим пропорционально-интегрально-дифференциальный контроллер, который установлен для динамического регулирования открывания дросселя (1) так, что давление в трубопроводе для нагнетания газлифта уменьшается и стабилизируется. Настоящая система позволяет максимизировать и стабилизировать добычу сырой нефти точным способом и без использования оборудования в нисходящей скважине.Международная заявка была опубликована вместе с отчетом о международном поиске.The control system for gas-lift production from an oil well contains a dynamically adjustable choke (1) for controlling the flow of crude oil from the production pipe (2) of the well. The throttle (1) is controlled by a control module containing a proportional-integral-differential controller, which is installed to dynamically control the opening of the throttle (1) so that the pressure in the pipeline for forcing gas lift decreases and stabilizes. This system allows you to maximize and stabilize the production of crude oil in an accurate way and without using equipment in a downhole well. The international application was published along with an international search report.
