中文摘要：

近年来，松辽盆地深层天然气勘探取得重大突破，因此松辽盆地深层油气问题也受到诸多学者的高度重视．本文以松辽盆地北部深层油气问题为研究目标，对纵波速度资料进行重新整理和分析，描述了六条人工地震剖面的构造特征，并对盆地内几大主要断陷进行了评价．本次研究对于深层形态的定性说明有一定可信性，利用六条长剖面从区域角度分析该盆地深层地层分布以及讨论与油气的关系，可以得到更全面的认识，对进一步的深层油气勘探具有指导意义．

英文摘要：

In recent years, deep gas exploration in the Songliao basin has achieved a major breakthrough, so many scholars pay much attention to deep oil-gas exploration in this basin. Aiming at the deep oil-gas in the northern Songliao basin, wemake a new collection and analysis of the P-wave velocity data to describe, the structured charac- teristics of six artificial seismic profiles. Finally, we evaluate several faulted subsidences in the basin. This paper qualitatively shows certain credibility of the deep model. Through analyzing the deep strata distribution of the basin and discussing the relationship between deep strata and oil-gas with six long seismic profiles, we can obtain more comprehensive cognition, iWhich will be of guiding significance for further exploration of deep oil-gas.
