【摘要】：得益于勘探认识的深化和技术的进步,四川盆地近期陆续发现了9个千亿立方米级大气田,截至目前已累计探明天然气储量3.69×10~(12) m~3,天然气年产量位居全国第二位。中石油组织的最新油气资源评价结果表明,四川盆地天然气资源量位居全国各含油气盆地首位,但探明率仅10%,故勘探潜力巨大。几十年来,该盆地已形成了先进的天然气工业技术体系、最完善的天然气区域管网、最成熟的市场,被中石油确定为中国天然气工业基地,故该盆地天然气大发展的各方面条件均已成熟。为此,中国石油西南油气田公司(以下简称西南油气田)适时推出五大天然气增储上产工程(川中地区多层系滚动勘探开发、川东北高含硫气田安全高效开发、川西北地区深层海相碳酸盐岩气藏勘探与开发示范、川东地区寒武系盐下大型构造气藏探索与发现、蜀南地区页岩气规模效益开发),以助推未来国内最大气区的早日建成。上述工程是实现中石油"西南增长极"的关键,涵盖四川盆地天然气重点、热点、难点领域,平面上几乎覆盖全盆地,纵向上包含多个含气层系。上述工程2020年预计天然气产量介于250×10~8~290×10~8m~3,占西南油气田规划产量300×10~8 m~3的绝大部分;2030年西南油气田有望达产500×10~8~700×10~8 m~3。可以预见,在未来相当长的一段时间内,四川盆地的天然气都将处于发展的黄金时代。
[Abstract]:Thanks to the deepening of exploration knowledge and the progress of technology, nine large gas fields of one hundred billion cubic meters have been discovered in Sichuan basin in recent years. Up to now, the cumulative proven natural gas reserves are 3.69 脳 10 ~ (12) m ~ (3), and the annual natural gas production ranks second in China. The latest evaluation results of petroleum resources of PetroChina show that the natural gas resource in Sichuan Basin ranks first in all oil-bearing basins in China, but the proven rate is only 10%, so the exploration potential is huge. Over the past few decades, the basin has formed an advanced natural gas industrial technology system, the most perfect natural gas regional pipeline network, the most mature market, and has been designated by PetroChina as the natural gas industrial base of China. Therefore, all aspects of natural gas development in this basin have matured. For this reason, China National Petroleum Southwest Oil and Gas Field Corporation (hereinafter referred to as Southwest Oil and Gas Field) has timely launched five major projects for increasing natural gas storage and production (multi-layer rolling exploration and development in central Sichuan, safe and efficient development of high-sulfur gas fields in northeast Sichuan). The exploration and development demonstration of deep marine carbonate gas reservoirs in northwest Sichuan, the exploration and discovery of Cambrian subsalt large structural gas reservoirs in eastern Sichuan, and the development of shale gas scale benefit in southern Shunan area will promote the early establishment of the largest gas region in China in the future. The above project is the key to realize the "Southwest growth Pole" of PetroChina. It covers the key, hot and difficult fields of natural gas in Sichuan Basin, covers almost the whole basin on the plane, and contains many gas-bearing formations in the longitudinal direction. The estimated natural gas output of the project in 2020 is between 250 脳 10 ~ (8) and 290 脳 10 ~ (8) m ~ (3), accounting for most of the planned output of 300 脳 10 ~ (8) m ~ (3) in southwest oil and gas fields, and is expected to reach 500 脳 10 ~ (8) ~ (8) 脳 10 ~ (8) m ~ (3) in 2030. It can be predicted that the natural gas in Sichuan Basin will be in the golden age of development for a long time in the future.
