摘　　要：通过分析天然气对原油高压物性的影响,研究了古潜山油藏的注气机理。筛选合理的注入压力、注入速度等参数,为预测注气开发效果、提高碳酸盐岩古潜山油藏开发后期采收率提供了依据。研究表明,任丘古潜山油藏的储层特性和流体性质较适合注气开采,其研究成果对现场实施注天然气开采具有指导意义。Gas injection mechanism in buried hill reservoir has been studied through analyzing the impact of gas on oil PVT.Reasonable injection pressure and rate can improve the development response of gas injection and the recovery factor of carbonate buried hill reservoir.The study shows that reservoir characteristics and fluid property of Renqiu buried hill reservoir fit gas injection recovery,and the result of this study may guide field recovery by gas injection.
