在大张坨凝析气藏地质研究的基础上 ,结合该气藏的生产、测试及高压物性分析资料对该气藏改建为我国第一座地下储气库进行了数值模拟研究。通过研究气藏边水的活动能力、凝析油采收率的变化、储气库的库容量等 ,对储气库的调峰能力作出正确的评价 ,促进我国天然气的发展和利用 Based on the geological study of Dachangliao condensate gas reservoir, the numerical simulation of the gas reservoir rebuilding into the first underground gas storage reservoir in China was conducted based on the production, testing and high-pressure physical property analysis data of the gas reservoir. By studying the activity of reservoir water, the change of condensate recovery, the reservoir capacity of gas storage, etc., we can correctly evaluate the peak regulation capacity of gas storage and promote the development and utilization of natural gas in our country
