Justification of the choice of recommended methods of operation, downhole equipment and calculation of gas lift lifts for dual completion wells

Based on laboratory studies, the article substantiates the scope of application, efficiency, reliability and the possibility of maximum extraction of oil reserves from multi-layer oil and gas horizons with a large depth of occurrence, composed of weakly cemented rocks. The article also considers the possibility of using various methods of mechanized oil production in relation to the conditions of the Altyguyi field. Calculations are given for a periodic gas lift, in relation to the operating conditions of the Altyguyi field, where it is recommended to equip wells with a single-row replacement chamber with a packer and a check valve installed in the lower part of the tubing. The method of designing gas lift lifts, including the arrangement of starting and working valves, in accordance with the standard ones, taking into account the properties of reservoir fluids and projected well flow rates, is presented. Based on the results of the conducted research, the justification of the choice of downhole equipment was carried out, taking into account the need for of dual completion (DC).
