Regional characteristic analysis of P-wave velocity and deep oil-gas in the northern Songliao basin
松辽盆地北部纵波速度区域特征分析及深层油气问题

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 characteristics 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.
