摘要
分析了油田地下地面一体化大系统优化问题的特点 ,讨论了各子系统间的关系 ,建立了地下地面一体化大系统优化数学模型 ,采用大系统优化理论 ,提出了分级分解求解方法。首先以油田企业总利润为目标优化确定最佳井数、经济开发期、单井产量、最终采收率等参数 ,同时借助油藏数值模拟技术将地下与地面有机地结合为统一的大系统。然后进行地面各子系统的优化。采用BorlandC ++Builder
Analyzed are features of optimization of large system overall plan for underground & surface engineering in oil field.Relations between subsystems are discussed.Established is an optimization mathematical model of large system and a multistage dismembering solving method is presented according to the theory of large system.Firstly,the best amount of wells,economical production time,output of single well and final recovery efficiency are determined to get the biggest benefit of oil field enterprise.In the mean time,utilizing the technology of numerical reservoir simulation,subsurface and surface are unified together as a large system.Then,the subsystems on the surface are optimized.Finally,the software of optimization of the large system for subsurface and surface engineering is gained with Borland C++Builder4.
