南海北部大陆架东区台西南盆地石油地质特征与勘探前景分析

台西南盆地是南海北部大陆架边缘盆地链上的中新生代含油气盆地之一,处在中国近海陆架盆地天然气富集区带的有利位置,具有良好油气资源潜力和勘探前景,迄今该区勘探及研究程度较低,仅在中央隆起带中部发现了CFC、CFS和CGF等含油气构造,且探井及研究亦主要集中于该带,对其它区块勘探及研究均十分薄弱。由于中央隆起带处在区域上有利油气运聚的低势区,具备了良好的油气运聚成藏条件,勘探发现的商业性油气也集中于该带,因此应加大勘探力度,全面解剖中央隆起带,深入研究其油气富集规律,这也是在台西南盆地尽快获得油气勘探突破的关键所在。

PETROLEUM GEOLOGIC CHARACTERISTICS AND EXPLORATION BASE OF TAIXINAN BASIN IN EASTERN AREA OF CONTINENTAL SHELF IN NORTHERN OF THE SOUTH CHINA SEA

Taixinan basin,which exists range of profitability of natural gas abundance zone in offshore shelf basin china,is one of petroliferous basin of middle Cenozoic era in marginal basin of the northern in south China sea with good resources base and exploration potential.This region belongs to the lower exploration search other than discovered petroliferous structures of CFC,CFS,CGF in central uplifted zone so far.Because central uplifted area is situated favorable migration region in middle basin with good accumulation conditions,centralized on commercial hydrocarbon discovery.Therefore,central uplifted zone of "two-sag" belongs to the maximum petroliferous abundance zone and prospective region,so as to enhance the exploration strength,make a thorough research abundance rule,obtain quickly break in Taixinan basin.
