基于可拓理论的深水油田储量分级评价方法研究

在综合分析深水油田地质特点和开发要求的基础上，从影响深水油田开发投资、生产效果、开发效益等方面出发，筛选出深水油田分类特征参数，并确定相应指标分级标准，进而构建出多级评价指标体系；针对深水油田特点，基于可拓理论方法，提出深水油田储量分级评价的基本步骤，并建立相应的深水油田储量评价的多级可拓综合评价方法。实例分析表明，本文方法能够较好地确定出深水油田储量级别，为深水油田的高效开发奠定了基础。

Evaluation method of reserve classification based on extension theory for deepwater oilfield

According to the comprehensive analysis on the geological characteristics and development requirements of deepwater reservoir ,the indexes of deepwater oilfield classification were screened and the corresponding standards of classi -fication indexes were determined and then a multilevel evaluation index system was built from many aspects ,such as devel-opment investment ,production effect and development effectiveness ,etc.Based on the extension theory ,the basic steps of reserve classification evaluation for deepwater oilfield were proposed and then the corresponding multilevel extension syn -thetic evaluation method was established .The example analysis shows that the method can well identify the reserve level of oil reservoir and lay a foundation for the efficient development of deepwater oilfield .
