“探明储量”怎么说？

中国科学院院士贾承造22日在北京召开的中国油气论坛上透露, 作为中国近年来最大的油气勘探发现之一，中石油冀东南堡油田有望在未来有更大的探明储量发现。那么，“探明储量”怎么说呢？

请看《中国日报》的相关报道：

"We estimate that we could have proven reserves of as much as 1 to 1.6 billion tons (oil equivalent) from the offshore blocks of our Jidong Nanpu oilfield in the Bohai Bay area," Jia Chengzao, vice-president of PetroChina and academician at the Chinese Academy of Sciences said.

"Including reserves from onshore, the ultimate proven reserves of Nanpu oilfield are expected to hit around 2 billion tons."

报道中说，中国科学院院士、中国石油天然气股份有限公司副总裁贾承造院士说，渤海湾地区冀东南堡油田海上将有可能探明10到16亿吨（油当量）的储量，加上陆上的储量，南堡油田的整个（探明）储量最终可能突破20亿吨。

这里，“proven reserves”就是“探明储量”，“ultimate proven reserves”是“最终探明储量”；“oilfield”指“油田”。
