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。
Conventional and unconventional oil and gas have relationships related to their origin and have characteristics related to their presence together. Regularity in their spatial distribution is very strong. Inside the most concentrated part of the source rock strata formation/bed(area) lie shale gas,shale oil,coal-bed methane,and oil shale.Shale gas,shale oil,CBM are already undergoing large scale development abroad,while in China CBM development is already making progress, shale gas development is just getting started,and shale oil development is still being looked into.Large-scale oil shale development faces more environmental problems, and producers should pay attention to conducting research on new technology.Tight oil and gas,water soluble gas, and a portion of lower permeable oil and gas gather mostly in the migrating layers.Tight gas and lower permeable oil and gas are already undergoing large-scale development abroad and in the Ordos,Sichuan and a few other basins in China.Conventional oil and gas,heavy oil and lower- permeable oil and gas gather mostly in the trap strata (area),and are all undergoing large scale development. Missing are areas for any major oil sands development, as the quality of China’s oil sands is rather poor and development is definitely difficult.After conventional oil and gas,then tight gas and CBM,then shale gas,shale oil is China’s next most realistic unconventional oil and gas resource to develop.China’s long-range natural gas resource potential is greater than its conventional natural gas resource potential.China should draft a long-term development program to strengthen exploration research and technology resources.This is crucial for China’s unconventional oil and gas resource development and oil and gas resource self-sufficiency.
