东海西湖凹陷局部构造钻探效果与油气勘探前景

The Result of Exploratory Well and Hydrocarbon - exploring Prospect in Xihu Trough, the East China Sea

本上通过西湖凹陷局部构造油气探井钻探成功率、发现油气层情况、单井控制油气储量的分析，提出进一步油气勘探方向：凹陷南部和保俶斜坡平中、平北地区是发现大、中型油气田，扩大储量规模的主要地区；浙东中央背斜带中、北部要重视发现浅层次生油气藏；保俶斜坡北、南部存在尚未钻探的古新统含油气圈闭。

Analysing the success of exploratory well, situation of oil and gas reservior discovering, oil and gas reserves conrtolled by single well in Xihu Troigh, the East China Sea, further exploring domains are suggested: south of the Trough and Pingzhong, Pingbei Zong in Baoshu Slope are main areas for discovering large - medium size oil and gas fields and greatly increasing reserves; Shallow secondary oil and gas pools should be think highly in the mid - and northern Zhedong Center Anticline Zone; Paleocenic petroleum trap may be occurred in northern and.southen Baoshu Slope, which not be penetrated up to now in Xihu Trough.
