东海陆架盆地与松辽盆地的类比分析

ANALOGY ANALYSIS OF DONGHAI SHELF BASIN AND SONGLIAO BASIN

松辽盆地在我国的含油气盆地中勘探程度较高，已探明了几十亿吨的地质储量，对控制盆地油气形成的生、储、盖、图、运、保等条件的研究也比较深入和细致，东海陆架盆地是我国目前勘探程度较低却有很大油气远景的盆地，这两个盆地都是我国东部中新生代大型复合沉积盆地，在地质构造上具有一定的相似性。本文试图通过东海陆架盆地与松辽盆地的对比在研究它们各自特征的基础上，寻找这两个大型沉积盆地的共同点和相似性，以便借鉴松辽盆地的油气勘探经验和油气聚集规律，开拓东海陆架盆地的找油思路，探索其找油领域，为下一步的油气勘探提供有益的帮助。

Of China's oil-and gas-bearing basins,thesongliao Basin has seen extensive explo-rations which reveal huge oil and gas reserves of n×10￣(10)T. And careful and detailed re-searches have also been done on the basin' s source bed,reservoir,caprock,trap,migra-tion and preservation of oil.The Donghai Shelf Basin,however, is only poorly explorednow,but it is also a great prospective oil and gas basin,Both the basins are large com-plex sedimentary basins formed during Mesozoic-Cenozoic era in the east of China,andsimilar to one another in geological structures.This paper tries to do a comparison between the two basins and to find their simi-larities,which can help do explorations in the Donghai Shelf Basin.
