摘要
大民屯凹陷太古宇鞍山群和中上元古界长城系结晶基底油气富集,印支、燕山和喜山运动使凹陷基底形成北东走向高、中、低潜山交替分布、平行排列的构造格局。受控于充足的油源和良好的运移通道、多种储集岩类型及良好的储集空间、断裂的多期与早期发育和优越的区域性盖层等有利成藏条件,凹陷基岩具有"整体含油、局部富集"的成藏特征。大民屯凹陷基岩具有巨大的深化勘探潜力,应加强有利储集区预测及保存条件研究,以获得更大的勘探突破。
The Damingtun depression Archean Anshan group and mideum - up Proterozoic Changcheng System crystalized bedrock is enriched with oil and gas,Indo- China,Yanshan and the Xishan mountain movement cause the depression bedrock to move toward northeast,and high,middle and low buried hill formed alternate distribution and parallel arrangement structure framework.Controlled with sufficient oil source and the good migration path,many kinds of reservoir rock type and the good reservoir space,fault multistage and early stage development and advantageous regional cap and so on,the depression bedrock bedrock has reservoir accumulation characteristics of'the whole oil-bearing,partial enrichment'. Damingtun depression bedrock has the huge deepened exploration potential,and we should strengthen the advantageous accumulation area forecast and the preserved condition research to obtain the bigger exploration breakthrough.
