摘要: 对由多个油田组成的海外深水开发项目区块,高效开发的关键是针对不同油田的特点,统筹规划不同油田投产次序和产量接替的组合方式,实现有效开发时间内的整个开发项目的最大收益。文中基于深水油田特点及开发要求,通过3个方面的研究来实现深水油区不同油田组合的储量动用及产量接替优化。一是建立深水油田储量分级评价标准,并利用数学综合评价方法确定不同油田的储量等级;二是通过分析深水油田产量运行主控因素,建立不同等级储量的关键开发指标预测模型,可作为不同油田组合开发下产量运行计算的基础;三是建立满足不同限制条件、开发效益最大的数学模型,并利用过程控制理论进行计算,优化得到不同储量等级油田的组合方式和逐次动用程序。将本文方法应用在XF深水油区的开发部署中,基于油田实际数据,进行了不同条件下、多个油田储量动用及产量接替方式的计算,优化结果符合实际开发需求,提高了深水油田开发决策的科学性。

Abstract: For a highly efficient development of overseas deepwater blocks composed of several oilfields,one should make an optimized master plan for producer on-stream sequence and production replacement,and tailor field development strategies for each oilfield according to their unique features.This also ensures the maximum project profits through the effective development optimization.Based on the features and requirements of joint development of multiple deepwater oilfields,we suggested three studies to be carried out to optimize reserve development and production replacement in various scenarios of combined deepwater oilfields development.(1)We established the evaluation standards for reserves ranking through comprehensive mathematical evaluation methods,and clarified the reserve ranks for various oilfields;(2)We established the prediction models for key development indexes for varying reserve levels via the analysis of main controlling factors for production and operation in deepwater oilfields,which can be used as the basis for the calculation of production operation under joint development of different oilfields;(3)We established the mathematical model to satisfy various constraints and to maximize project NPV profits.Process control theories were applied to select the best combination pattern and the optimized drilling sequence for varying ranks of reserves.Application of the methods proposed in this study to the development and deployment of XF deepwater oil region based on the actual oilfield data,we calculated the petroleum reserves for development and the strategy of production replacement to optimize multiple oilfields development under different conditions.The results meet the actual development requirements,so ultimately enhancing the reliability of deepwater oilfield development decisions.

Key words: mathematical model, optimization calculation, production replacement, reserve classification, joint development of multiple fields, deepwater oilfield
