Optimization of equipment parameters and a well operational mode with ESP under conditions of complications
The paper considers the difficulties associated with the problems formalization of optimal management of the complicated well fund with electrical submersible pumps (ESP). The classical synthesis scheme: from models to algorithms, in the practice of optimal design is more reliable in reverse execution - from problems and solutions to models serving these solutions with the determination of the best result. The aim of the research is to formalize the problem of optimizing the control of parameters and operating modes of a well with an ESP under the conditions of the action of complicating factors, an example of optimal design, a computational analysis of the properties of the resulting optimal solutions. The considered approach to optimizing the modes and parameters of well operation has a hierarchical scheme for a control algorithm construction that corresponds to organizational, technical and regulatory information resources, the operating schedule of the ESP to failure, and the temporal nature of complications manifestations. The factor completeness of the description of the operation problematic aspects, the justification and formalization of the target indicators of the best solutions, are of the first priority in determining the law of optimal control. The considered variant of optimal control is based on the introduction of the secondary models of the complication evolution. The practical implementation of such solutions is possible in the class of self-learning systems.
