美国页岩油勘探开发现状与前景展望
|
摘要
系统介绍了美国页岩油(致密油)勘探开发现状与发展前景。目前,美国页岩油区带分布广泛,遍及二叠盆地、威利斯顿盆地、墨西哥湾盆地和阿纳达科盆地等。页岩油储量总体呈增长趋势,2017年末页岩油证实储量占全美石油证实储量的比例接近50%。美国页岩油产量主要来自二叠盆地、巴肯和伊格尔福特三大页岩油区,目前其产量占全美页岩油产量的近80%;有利地质条件是这三大页岩油区发展的基础。受2014年油价暴跌影响,美国页岩油气作业钻机明显减少,页岩油产量有所下降;但自2016年中期开始,产量恢复增长,屡创新高。美国待发现的页岩油资源丰富,具有良好的发展潜力。根据预测,未来10年页岩油产量还将持续增长,是美国原油产量增长的主要来源。
Shale oil( tight oil) plays are widely distributed in Permian,Williston,GOM,Anadarko and many other sedimentary basins in the U. S. The proved reserves of shale plays keep increasing year by year and account for about half of U. S. proved crude oil reserves. Approximately 80% of shale oil production comes from Permian Basin,Bakken and Eagle Fords plays. Favorable geological conditions are the fundamental factor for the shale oil development in the U. S. Affected by the slump in oil prices in 2014,the count of active rigs in the U. S. shale plays dropped dramatically,leading to the decrease of shale oil production. But the growth of shale oil production has recovered and made new highs since mid-2016,indicating a great potential for shale oil development in the U. S. The U. S. shale oil production is expected to keep increasing in the next decade,and to be the primary source of oil production growth in the U. S.
