1、中国非常规油气资源【摘要】常规、非常规油气资源具有成因联系和共生特征。油气资源的空间分布规律性很强。源岩层系(区)内主要富集有页岩气、页岩油、煤层气和油页岩,其中前三者在国外已实现规模化开发,国内的煤层气开发已经取得进展,页岩气开发正在起步,页岩油开发还在探索,油页岩规模化开发面临较大的环境问题,应关注开发新技术研究。运移层系(区)内主要聚集致密油气、水溶气和部分低渗油气,致密气和低渗油气在国外已规模化开发,国内在鄂尔多斯、四川等几个盆地已大规模开发。圈闭层系(区)主要聚集常规油气、重油和低渗油气,这些油气资
2、源均已大规模开发。散失区为油砂的主要发育区,国内油砂品质较差,开发有一定难度。继常规油气、致密气和煤层气资源之后,页岩气、页岩油是我国最现实的待开发非常规油气资源。我国非常规天然气资源潜力远大于常规天然气,国家应制定长期发展规划,加强探索性研究和技术准备,这是我国非常规油气资源发展和提高油气资源自给能力的关键。【Abstract】Conventionalandunconventionaloilandgashaverelationshipsrelatedtotheiroriginandhavecharacter
