Изобретение позволяет повысить эффективность фонтанной эксплуатации нефтяных малодебитных скважин с высоким газовым фактором за счет рационального использования энергии газа. Лифтовую колонну разобщают установленными в муфтовых соединениях перегородками, выполненными из упругого материала и имеющими прорези, образующие в перегородках упругие лепестки, отгибающиеся под воздействием газожидкостного потока. При эксплуатации скважины проходное сечение в перегородках регулируется в зависимости от величины расхода газожидкостной смеси. Чем выше расход, тем больше площадь проходного сечения и эффективность перемешивания, обеспечивающего устойчивость смеси. При остановке скважины лепестки перегородки смыкаются и отделяют полости между перегородками одна от другой, предотвращая прорыв газа и стекание жидкости. При повторном пуске скважины газ перемешивается с жидкостью одновременно по всей длине лифтовой колонны и скважина выходит на режим фонтанирования.The invention allows to increase the efficiency of the fountain operation of low-yield oil wells with a high gas factor due to the rational use of gas energy. The lift column is divided by partitions installed in the coupling joints made of an elastic material and having slots forming elastic leaves in the partitions, which are bent under the influence of the gas-liquid flow. During well operation, the flow area in the partitions is adjusted depending on the flow rate of the gas-liquid mixture. The higher the flow rate, the greater the flow area and mixing efficiency, ensuring the stability of the mixture. When the well is stopped, the partition lobes close and separate the cavities between the partitions from one another, preventing gas breakthrough and liquid flowing off. When the well is restarted, the gas is mixed with the liquid at the same time along the entire length of the production tubing and the well enters the fountain mode.
