基于属性理论的海上油田开发效果评价——以渤海Y油田为例

Evaluation Method of Offshore Oil Field Development Effect Based on Attributive Theory: Taking Y Oil Field of Bohai as an Example

为了进一步改善油田开发效果,利用属性理论将多目标评价问题转化成单目标评价问题,探讨海上油田开发效果评价方法。将评价方法应用于渤海Y油田,结合各井组评价结果,建立了渤海Y油田合理采油速度、提液时机、阶段注采比等油藏管理指标模板。

In order to further improve oilfield development effect,the multi-objective evaluation method is transformed into the single objective evaluation in this paper based on the theory of attribute mathematical theory. Applying the evaluation method to Bohai Y Oilfield,the reservoir management index template is set up according to the oil recovery rate,the time of extraction and the injection production ratio and other indicators,combined with the evaluation results of each well group.
