摘要(Abstract)：

L油田是一个层状砂岩气顶油藏,为合理利用天然气资源,建设了地下储气库,而气顶油藏开发中的关键问题就是确保油气界面的稳定,避免油、气间的相互窜流。由于油气区的同时开发,储气库的调峰能力、生产运行不仅受储气库容量的控制,还受到油区生产状况的限制,使得保持油气界面稳定性的难度加大。为此,应用理论公式计算,结合储气库运行实际、压力分布状况等,综合确定了储气库的理论和实际调峰能力以及单井注采气能力。在此基础上,应用数值模拟技术,确定了调峰需求与气井开井数之间的关系,给出了储气库运行过程中的优化运行方法。调峰能力及优化方法的合理确定,能有效指导储气库年度注采气运行的安排,确保油气界面的稳定。
Oilfield L is a layered sandstone gas cap oil reservoir,in order to utilize the natural gas resources reasonably,the underground gas storage was constructed,but the key problem in the development of the gas cap reservoir is to ensure the stability of the oil-gas interface so as to avoid the channeling between the oil and gas.Due to exploiting the oil and gas blocks at the same time,the peak regulating capacity and operation of the gas storage is not only controlled by the amount of the gas storage,but also limited by the conditions of the oil block production,so it is harder to keep the stability of the interface.Therefore,by applying the theoretical formula to calculate,combining with the actual operation and pressure distribution of the gas storage,the theoretical and the actual peak regulating and injection-production capacities of the single well are determined comprehensively.On this basis,with the help of the numerical simulating technology,the relationship between the demand of the peak regulation and the number of opened gas wells are ensured,finally the optimal operating methods for the running process of the gas storage are presented.The Rational determination of the peak regulation capacity and optimizing method can effectively guide the annual gas injection-production arrangements of the gas storage,thus the stability of the oil-gas interface can be ensured.
