摘要
海礁凸起油气化探异常为其深部前新生代沉积盆地油气藏物质向上渗逸的结果。在久米 -鱼山大断裂以北的东海陆架盆地 ,除了继续探找新生代油气藏外 ,还要寻找古气新储、深源浅出的油气藏 ,这是东海油气勘探的新领域。东海大油气藏和油气田主要的气源岩可能是古生代地层。
WT5BZ]The hydrocarbon geochemical exploration anomalies of raised submarine reefs are the result of reservoir matter in the deep Precenozoic sedimentary basin leaching upwords.In the East China Sea Shelf Basin on the north of the Jiumi Yushan Major Fault,we should not only continue to look for the Cenozoic oil and gas pools,but also find the oil and gas pools in shallow strata whose hydrocarbon is from deep sources and is formed in the Paleozoic and accumulated in the Cenozoic.This is the new domain of oil and gas exploration in the East China Sea.The major gas source rocks of large oil and gas pools/fields in the East China Sea may be the Paleozoic strata.
