复杂成组凝析油气田开发规划的递阶优化方法

对于带油环带底水的复杂成组(多个)凝析油气田,本文在研究解决开发中的综合技术经济问题的基础上,提出并实现了运用动态规划进行单个疑析油气田最优开发规划的思想,提出并初步运用了大系统分级规划及递阶控制原理进行复杂开发系统最优规划的思想。本文建立并求解了复杂成组凝析油气田开发系统最优规划的二级递阶优化数学模型。第一级是高阶的总体最优协调模型,第二级是低阶的动态规划模型群。并将全部研究成果应用于解决我国华北苏桥地区复杂成组凝析油气田开发系统最优规划决策问题。

HIERARCHICAL OPTIMIZATION OF DEVELOPMENT PLANNING FOR COMPLEX GROUPED OIL-GAS CONDENSATE RESERVOIRS

For complex grouped oil-gas condensate reservoirs with crude oil and bottom water, this paper, based on the studies and solutions of the comprehensive technico-economical problems involved in the development,not only presents and achieves the thought of local optimal development planning for single reservoirs using dynamic programing, but also creates and preliminarily utilizes the thought of overall optimal development planning for complex grouped reservoirs using hierarchical decision-making and hierarchical control principles in large-scale system.
