近年来,随着国民经济的持续快速发展,我国油气需求量逐年攀升,原油对外依存度逼近60%。因而,寻找我国未来油气资源的突破口,意义重大。我国未来资源突破口有可能出现在常规、非常规油气资源两个层面。具体表现在我国东部老油田挖潜稳产、中西部油气田勘探增储、海域勘探开发加速以及页岩气等勘探开发实现突破等多个方面。我国油气资源丰富,各类沉积盆地逾500个,沉积岩面积达670×104km2。其中,中、新生界沉积岩厚度大于1 000m的沉积盆
In recent years, with the sustained and rapid development of the national economy, the demand for oil and gas in our country has been rising year by year, and the dependence on crude oil has been approaching 60%. Therefore, looking for a breakthrough in China’s future oil and gas resources, is of great significance. China’s future resource breakthrough may appear in the conventional, unconventional oil and gas resources at two levels. This is manifested in the aspects of tapping the potential for steady production in the old oilfields in eastern China, increasing exploration and accumulation of oil and gas fields in the central and western regions, accelerating exploration and development in the sea area, and breakthroughs in exploration and development of shale gas. China is rich in oil and gas resources, with more than 500 sedimentary basins and 670 × 104km2 sedimentary rocks. Among them, sedimentary basins of Meso-Cenozoic sedimentary rocks whose thickness is more than 1 000 m
