| 摘 要： | 针对火山岩气藏已成为中国石油重要的天然气勘探和开发的主要领域之一,利用恒速压汞技术研究了大庆徐深火山岩气藏岩芯的微观孔隙结构及其分布规律。研究表明:不同渗透率的低渗气藏岩心,其孔道半径基本相同,而喉道半径不同,对于所测得的不同渗透率的火山岩气藏岩芯来说,大约60%的喉道半径小于0.8μm。这与低渗透砂岩油藏岩芯的恒速压汞测试结果不同。平均喉道半径与渗透率有很好的相关关系。提出用平均喉道半径作为低渗气藏储层评价指标参数,来表征气体通过储层的难易程度。该研究成果对低渗气藏的分类评价和合理高效开发提供科学的决策依据

| Abstract: | The volcanic gas reservoir has become one of the main fields of gas prospecting and development in China.The volcanic gas reservoir exceeds 3,000 billion m3.It is discovered in Songliao Basin,Zhunger Basin and Bohai Bay Basin recently,and is the point of recent prospecting and development.This paper studied the microcosmic pore configuration and distribution of Xushen volcanic gas reservoir by using constant rate mercury penetration technology.The research indicates pore radius is basically the same and thr... |
