基于灰色关联的产量递减因素分析

Abstract

Abstract:

The production decline rate is an important indicator in evaluating the oil field development. It is of great significance for the development of oil fields to make the corresponding adjustment measures by analyzing the main factors that affect the production decline. The relation between the decline rate and the influencing factors for the development units of JS oilfield was studied by the grey correlation analysis method and based on the static and dynamic data. The weight of each factor was determined and the influence factors were sorted. According to the degree of influence for different factors, it can provide the reference for the development measures and development techniques.

Key words: decline rate, oilfield development, gray correlation, weight
