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。
Based on the study of solving the comprehensive technical and economic problems in development, this paper proposes and implements a single analysis of the optimal development plan for oil and gas fields using dynamic programming The idea of hierarchical planning and hierarchical control of large systems is proposed and initially applied to the optimal planning of complex development systems. This paper establishes and solves the second-order hierarchical optimization mathematical model for the optimal planning of complex group condensate field development system. The first level is a high-level overall optimal coordination model, and the second level is a low-order dynamic programming model group. And all the research results are applied to solve the optimal planning and decision-making problems of the complex group of condensate oil and gas field development system in Suqiao, North China.
