【摘要】 应用最优控制理论研究凝析气藏循环注气最优开发决策是特殊油气田开发方案设计的新尝试。研究结果表明：通过对气藏开发过程中的注气速度、采气速度和注入剂组成等进行优化，不仅能有效地提高凝析油采收率，而且还明显地改善了气田开发的总体经济效益。所研制的优化决策软件在特殊油气田开发决策自动化设计方面也迈出了可喜的一步。更多还原

【Abstract】 A new method to investigate optimal development decisions of gas-cycling in condensate reservoirs is presented. It is shown that both the oil recovery and the total net present value of a condensate reservoir can be enhanced obviously through optimization of gas production rate, gas injection rate and the mole fractions of each component in injection gas. The corresponding computer program makes a progress in automatic optimal design of development of condensate reservoirs.更多还原
