摘要： 针对川西主力气田目前普遍存在的由于配产不合理所造成采气成本偏高、气藏稳产期短、产量递减快等一系列问题, 提出一套对川西气田进行成组划分, 实施整体优化配产的新方法。以最小化单位采气成本为目标, 建立起成组气田开发最优配产规划数学模型, 以井次与产量的关系拟合为非均匀布井问题的解决手段, 并采用一种新型的优化技术——改进遗传算法进行了求解, 获得川西成组气田开发最优配产规划方案, 为决策者对全气田的宏观管理提供定量依据。与现行开发方案相比, 能够使单位采气成本明显降低, 效果显著。

Abstract: A series of problems occurred in major Chuanxi (west Sichuan)gas fields due to unreasonable production allocation that resulted in higher cost, short stable-production cycle and rapid production decline. This paper presents a set of new methods for clustered partition and integrated optimization of production allocation for these gas fields. On the basis of these methods or mathematical models, the optimum planning schemes are obtained, which provide quantitative basis of macro-control of all these gas fields for the decisionmaker (s). Comparing with existing development schemes, the studied results in this paper show that the unit cost for gas production can be obviously decreased. Integrated
