| 摘 要： | 对任11裂缝性底水油藏注气提高采收率的可行性进行了研究,评价了注气地质特征和水驱开采特征。同时,借鉴雁翎油田注氮气驱油试验成果,进行了注气驱油机理和流体界面运动规律的研究,提出了注气采油方案,并分析了地下储气库与提高采收率的协调关系。结果表明,任11裂缝性底水油藏的盖层具有良好的密封性,可以形成次生气顶和富集油带,具备注气提高采收率和建立地下储气库的地质条件。同时表明裂缝性潜山油藏注气与建设地下储气库相结合可以提高原油采收率。

| Abstract: | The feasibility of enhanced oil recovery (EOR) of Ren 11 fractured bottom water reservoir by gas injection was studied. The geological characteristics of gas injection and production performance by water flooding were comprehensively studied and evaluated. Based on the tested results of oil displacement by nitrogen injection in Yanling Oilfield, the mechanism of oil displacement by gas injection and the movement rules of fluid interface were investigated. A plan for producing oil by gas injection was worked out. The relation between underground gas storage and EOR measures was coordinated. The results show that the cap rock of Ren 11 fractured bottom water reservoir has good sealing property, and secondary gas cap and oil enrichment zone can be formed there. The geologic condition of Ren 11 reservoir is suitable for gas injection to enhance oil recovery and for establishment of underground gas storage. It is suggested that oil recovery can be improved in fractured buried hill reservoirs by building underground gas storage while injecting gas. |
