摘要
数据显示,全球前寒武系-下寒武统烃源岩生成468亿桶油当量探明和控制常规油气可采储量,前寒武系-下寒武统原生油气藏油气储量300亿桶油当量。国际上通常将埋深超过4500米定为深层油气。深层已成为21世纪初期全球探明储量增长的主体。截至2020年底,世界范围内已发现32个深度超过8000米的油气藏;全球深度超过9000米的油井超过10口。从全球来看,目前已发现的超深层油气储量占世界总储量的40%。
While the global ultra-dep oil and gas exploration is in full swing,china's ultra-deep oil and gas exploration has also made continwousbreakthroughs: the ultra-deep natural gas reserves of large gas fields sucha8 Kuga and Yuanba ecced one tilion cubic meters;the Tabei-Tazhongtransition zone (7200-8500 meters), Kuqa Keshen-Dabei (6900-7500meters) and other ultra-deep oil have made major breakthroughs.
