Designing of distributed systems of hydrolithosphere processes parameters control for the efficient extraction of hydromineral raw materials

Abstract

Using methods developed for systems with distributed parameters allows us to optimize processes of hydromineral raw materials production in practice. In accordance with the theory of distributed systems, formation of control actions on each well of a complex of production wells requires taking into account a state of the entire complex of wells, which ensures better dynamics and accuracy of a control process. The methodology of constructing distributed control systems for controlling the entire complex of wells involves the use of dynamic and static characteristics of an exploited aquifer. In this connection, a problem of mathematical description (identification) of the processes under consideration arises, which can be realized, for example, using the methods and formulas of Theis-Jacob. Using the Theis-Jacob formulas for the identification of the processes under consideration assumes an availability of information about parameters of hydrolytosphere processes (piezoelectric conductivity, overflow coefficients, etc.). The calculation of the considered parameters is a rather laborious task. The article proposes a methodology for constructing approximation models of the processes under consideration based on experimental studies using 2 wells of a field. Based on the obtained approximation model, a synthesis of the system for the hydrolytosphere processes parameters control was implemented.

Development of a Distributed Mathematical Model and Control System for Reducing Pollution Risk in Mineral Water Aquifer Systems

“…Analysis of modern research has made it possible to determine a set of effective methods for modeling hydrogeological objects, which are most often used to solve problems in this subject area [3,5]. As a result of the presented methods effectiveness analysis for the further research, the method of a mathematical description of the hydrogeological object in the form of a three-dimensional geo-filtration model was chosen.…”

“…Mathematical modeling is one of the relatively universal ways to visualize what is happening in the reservoir before its development, i.e., at rest or in the initial state, as well as during its operation. The task of mathematical modeling of a field is to visualize all processes, and since the simplest way of information perception for a person is visual perception, therefore, a mathematical model of a reservoir is able to partially simplify a person's work with the development and operation of a field [5]. Absolutely adequate is the fact that it is impossible to build a universal mathematical model of the reservoir, since each field is unique.…”

“…Most of the mineral water fields has difficult conditions for the occurrence of fluid in the reservoir. Extraction from that kind of fields is complicated by a huge number of factors affecting the state of the reservoir [5,6]. In the view of the greatest study, the fields of the Caucasian mineral waters (CMW) region where the large volumes of mineral waters with a unique chemical composition are extracted were chosen as a test object.…”

In this study, the tasks of improving the theoretical foundations of managing natural geological objects under conditions of intense technogenic impact, increasing the accuracy and efficiency of managing the processes of field operation, and substantiating development conditions with minimal environmental impact are solved.…”

“…This applies to all mineral water fields located in the region of the Caucasian Mineral Waters [5]. Due to the mentioned above, there is a potential danger of the mineral water fields' degradation [6,7].…”
