摘要
东海油气勘探已经历了25年历史,投资约24亿元,完成17万公里地震测线和47口钻井,发现8个油气田和6个含油气构造,获探明加控制储量2亿多吨。东海新生代盆地先后产生了三次重大的陆壳裂离改造及演化,从而奠定了新生代不同时期成油气物质基础的建造。第一次裂离地区主要是寻找古新统领域的油气;第二次裂离地区主要是寻找始新统、渐新统和中下中新统领域的油气;第三次裂离地区是寻找中上中新统领域的油气,其中第二次裂离区为重点勘探地区,应尽快多找到一些大中型油气田。
The petroleum exploration has been taken for over 25 years in the East China Sea.About 2. 4 billion of RMB have been invested, 170 000km of seishac lines have been taken, and 47 wells have been drilled in the area. So far, 8 oil and gas fields, 6 oil and gas hedring structures, and over 200 000 000 tons of oil equivalent in place have been found in this area. 3 times of major breaking have been happened in the conhnental cr-ust of the East China Sea and a lot of olefiant materials have been deposited in the Cenozoic basin of the area. The area where the rirst breaking took place can be the exploration target for Paleocene oil and gas. The area where the second breaking took place can be the exploration target for the Deene, Oligocene, eary Miocene and middle Miocene.The arca where the third breaking took place can be the exploration target for middle and late Miocene. The area where the second breaking took place should become main target of exploration and more large and middle oil and gas fields may be found in this area.
