中国天然气勘探开发前景

根据新一轮全国油气资源评价成果,我国天然气资源丰富,资源量达35.03×10¹² m³,其中可采资源量为22.03×10¹² m³,主要分布在塔里木、四川、鄂尔多斯、东海、柴达木、松辽、莺歌海、琼东南和渤海湾等9个盆地。通过对中国天然气资源勘探开发现状和资源潜力的深入剖析,预测了中国天然气储量和产量未来的增长趋势：2030年前,中国天然气探明地质储量将保持高速增长,年均探明天然气4 500×10⁸ m³;天然气产量将快速上升,预计2010年将达到1 000×10⁸ m³,2020年接近2 000×10⁸ m³,2030年达到2 500×10⁸ m³。进而指出了我国天然气的主要勘探领域是中西部叠合盆地的前陆和克拉通古隆起、渤海湾和松辽盆地的深层以及海域盆地,沁水盆地和鄂尔多斯盆地的东缘是煤层气勘探开发的有利区。最后,提出了促进中国天然气产业发展的建议：加强基础地质工作、实施重大科技攻关、适当提高天然气价格、加快天然气管网建设、加快煤层气产业发展,持续开展资源动态评价工作。

EXPLORATION AND DEVELOPMENT PROSPECTS OF NATURAL GAS RESOURCES IN CHINA

According to the newest statistical report, natural gas resource in China is abundant with 35.03 tcm in total, among which the recoverable resource of 22.03 tcm has been discovered in 9 main basins including the Tarim basin, the Sichuan basin, and the Ordos basin, etc. Based on in depth investigation into gas resource potential and the status quo of gas exploration and development, this paper forecasted how the increasing trend of gas reserve and gas production would be in the coming years. It predicted that the explored gas reserves would be on increase with 450 bcm of the annual explored gas resource by the year of 2030; the gas production would rapidly increase up to 100 bcm by 2010, 200 bcm by 2020, and 250 bcm by 2030. This paper also pointed out that important exploration area would be foreland areas of the middle and west basins, Claton palaeohigh, the Bohai Bay, the deep Songliao basin, and basins in sea area, and sound CBM exploration area would be the Qinshui basin and the eastern Ordos basin. In the end, this paper suggested that natural gas industry should be stimulated and encouraged by many ways such as infrastructure works to be well done, important techniques and technology to be applied practically, gas price to be appropriately adjusted, gas pipeline network to be quickly completed, CBM gas to be developed, and resource dynamic assessment to be sustained as well.
