世界大油气田形成的构造背景及其对勘探的启示

面对当前国内油气资源供求关系日趋紧张的形势,寻找能对国民经济起支柱性作用的大油气田已成为一项紧迫的任务。为了借鉴国际勘探的成功经验,在介绍了美国学者Mann P等人对世界大油气田研究的最新成果《Tectonic Set-ting of the World’s Giant Oil and Gas Fields》的基础上,结合我国勘探实践,认为国内以下新领域和新地区具有发现大油气田的巨大勘探前景:(1)南海北部陆坡深水区;(2)大型叠合盆地的海相油气成藏组合;(3)东部大型成熟勘探盆地的新层系;(4)地层型油气藏。

Tectonic setting of the world's giant oil and gas fields and its revelation for hydrocarbon exploration

Since 1990's,the domestic hydrocarbon consumption grows so rapidly that it outpaces oil production.The paper introduces study conclusions on giant oil and gas fields in the world written by American scholar Mann P.et al.up to date: Tectonic Setting of the World's Giant Oil and Gas Fields.Using successful world experience and domestic exploration practice for reference,this paper indicates Chinese petroleum geologists should use new thoughts to enter into new domains and areas for giant oil and gas fields.As for this,the authors summarize that the following domestic domains and areas possess huge potential for giant oil and gas discoveries:(1) deep-water areas of the north shelf of the South China Sea;(2) marine oil-gas play of big superposed basins;(3) new formation of the big highly exploration-matured basin in the eastern China;(4) stratigraphic type oil-gas reservoirs.
