摘要: 000年以来,南海油气勘探开发快速发展,特别是深水区获得了重大天然气发现,但对该区的天然气资源认识程度较低,出现了勘探实践与南海资源评价结果不符的情况。因此,需要系统开展南海海域天然气资源评价,科学地认识南海海域天然气资源潜力。在归纳南海油气勘探新进展及油气地质新认识的基础上,总结了构造型、生物礁地层型、深水沉积岩性型及基岩潜山型4类天然气成藏模式,将台西南、北部湾、珠江口、琼东南、莺歌海、中建南、双峰、万安、南薇西、北康、曾母、文莱沙巴、南薇东、礼乐及西北巴拉望等15个主要沉积盆地作为资源评价对象;选择“以多参数类比法为主、以成因法和统计法为辅”的资源评价方法,建立了万安、文莱沙巴和珠江口等3个类比刻度区,代表断陷、走滑和前陆3类不同类型的沉积盆地,通过刻度区精细解剖,系统获得了南海天然气资源面积丰度等关键参数,最终利用特尔斐法综合,预测15个主要沉积盆地的天然气地质资源量为31.85×1012m3,明确了南海常规天然气勘探潜力及未来勘探方向。
