Abstract
Currently, solving the problems of choosing a strategy for managing the process of oil deposits development with fractured-porous reservoirs is associated with a number of difficulties due to changes in the filtration and capacitance characteristics of the formations along the section and area, the presence of nonequilibrium effects, insufficient geological and field information, and the complexity of technological processes of offshore oil production etc. In this regard, increasing attention is being paid to the use of methods that make it possible to analyze the processes occurring in formation systems by processing indirect but accessible information, for example, flow rates of individual wells, production from areas and horizons, etc.
The article discusses the problems of diagnosing the state of development of oil deposits with fractured-porous reservoirs and the principles of process regulation based on the cybernetic approach to the analysis of geological field information by an indirect method, such as analysis of the Gini coefficient.
The Gini coefficient is used in economics to measure inequality in the distribution of a society's total income and the standard of living of different segments of the population. By analogy, it was used to determine the inequality in the distribution of oil and water withdrawals among the wells of the field under consideration during different periods of development. It has been established that the use of the Gini coefficient when interpreting geological and field information significantly increases the reliability of diagnosing the current state of the development process, which allows timely to make decisions on regulating the technological process.
Based on a dynamic approach to the analysis of geological and field data, the article proposes principles for managing the development process of a fractured-porous reservoir of the oil field in question. The proposed analysis method for managing the process of developing oil deposits with fractured-porous reservoirs had good adaptation in the process of developing the field in question
