Evaluation of well interference by correlation analysis
[摘要] The analysis of well interference is understood as an assessment of the presence or absence of pressure communication, the calculation of the response time of production wells to the change in pumping of injection wells, as well as the evaluation of the contribution of injection wells to production wells flow rate. The problem of determining the interference of wells at the moment is solved by several methods, which can be divided into 2 groups: 1. Traditional methods. Methods of data analysis that require any technological operations on the investigated wells (observation well testing, tracer studies). 2. Alternative methods. Various methods for analyzing field data using mathematical statistics or by numerical modeling of the behavior of pressure or flow in specialized software. The optimal option is a comprehensive approach based on the principles of the correlation method of analysis of field data, the main advantage of which is the speed of analysis and decisions, as well as the lack of large capital investments needed.
