世界页岩气资源现状研究

A Study on the World′s Shale Gas Resources Today

页岩气的勘探开发引起国际社会的高度关注,其资源分布与资源潜力成为研究的热点。页岩气资源主要分布于北美、中亚、中国、中东、北非和非洲南部等国家和地区。据EIA最新的评价结果,全球页岩油和页岩气技术可采资源量分别为473×108t和207×1012m3,分别占油气资源总量的10%和32%。中国页岩气和页岩油技术可采资源量分别为31.6×1012m3和44.1×108t,分别居世界首位和第三位。世界页岩气技术可采资源量排名第二位、第三位的国家分别是阿根廷和阿尔及利亚,资源量分别为22.71×1012m3和20.02×1012m3。俄罗斯拥有102.19×108t页岩油技术可采资源量,居世界首位,阿根廷、利比亚、委内瑞拉和墨西哥等国也拥有丰富的页岩油资源。非常规油气已成为全球油气供应的重要组成部分,非常规油气产量占油气总产量的比例已超过10%。非常规油气勘探开发技术取得的成果包括连续型油气聚集理论、水平井规模压裂技术、平台式"工厂化"开发模式。将多学科的先进技术综合应用到勘探领域,是目前页岩油气勘探技术的发展方向。以美国为首的西方发达国家将继续引领全球页岩气勘探开发技术的潮流。

Shale gas exploration and development has drawn wide attention from the international community and the distribution and potential of this gas is becoming the focus of study.Shale gas resources are primari- ly distributed in North America,Central Asia,China,the Middle East,North Mrica,and southern Africa.EIA＇s latest assessment results show that the world＇s technically recoverable shale oil and shale gas resources stand at 473×108t and 207×10-12m3 respectively,accounting for 10% and 32% of the world＇s total oil and gas re- sources.China has 31.6xl01Zm3 of technically recoverable shale gas resources and 44.1×108t of technically re- coverable shale oil resources,the highest and third highest worldwide.China is only behind Argentina and A1- geria in terms of technically recoverable shale gas 20.02×10-12m3 of such resource.Russia has 102.19×108t resources,which respectively have 22.71 ×1012m3 and of technically recoverable shale oil resources ,the high- est in the world.Argentina,Libya,Venezuela,and Mexico also have rich shale oil resources.Unconventional oil and gas are now important parts of the global oil and gas supplies and the world＇s unconventional oil and gas production now accounts for more than 10% of the total oil and gas production.Achievements in uncon- ventional oil and gas exploration and development technology include the continuous accumulation theory, large-scale horizontal well fracturing technology,and platform-based factory-like development.A trend in the development of shale oil and gas exploration technology is apparent that multi-disciplinary advanced technolo- gies are being introduced in the exploration sector.Developed countries,led by the United States,will continue to lead the development of shale gas exploration and development technology.
