Abstract

Benefit classification analysis is an important content for not only studying the benefit categories of different blocks in Oilfield, but also controlling and adjusting the negative benefit blocks. Due to the lack of comprehensive consideration of development stage and geological conditions, the classification of oil field development units has some limitations. Through comprehensive analysis of the influencing factors of oilfield development benefit, this paper classifies unit development by using system clustering method. DEA (Data Envelopment Analysis) model is used to analyze the relative validity of different development units. In the same geological and development condition units, the method of benefit classification based on validity analysis is used to realize the comprehensive classification of development and economy. Benefit classification analysis using the benefit evaluation data of a low permeability development unit in eastern oilfield shows that it can play a guiding role in benefit classification, negative effect management and operation strategy of the development unit.
