When operating oil wells, one of the key technological operations is the selection of the optimal operational mode of electric submersible pumps (ESP), the efficiency of which determines the provision of stable and cost-effective oil production, with minimal costs for maintenance and repair of submersible equipment. The complexity of the task lies in the necessity of a one-time analysis of such parameters as pressure, liquid flow rate, temperature, submersible electric motor (SEM) load, SEM rotation speed, etc. Optimal selection of the ESP operational mode determines the economic efficiency and stability of the entire reservoir – well – pump complex. Optimization of the ESP operational mode allows for the selection of the most balanced point of reservoir operation (bottomhole pressure), which helps to increase the efficiency and durability of the equipment. Taking into account the complexity of establishing the interrelation between a lot of factors affecting the efficiency of the pump operation, the mode fine-tuning is one of the key elements of increasing the overall profitability of oil fields development and operation.
The authors of the article have developed an algorithm for selecting the optimal ESP operational mode in the reservoir – well – pump system in the form of a program code, which takes into account the dynamics of key operational parameters. As part of solving the problem of the algorithm development, the following variable parameters were collected and analyzed: liquid and gas flow rates, pressure at the ESP intake, temperature and SEM rotation speed.
