摘要：

松辽盆地深层系统的地震资料构造解释表明,断陷期的3 套地层具有不同的形成发育过程，原始展布特征和现今残留状况。断陷期经历了一个完整的盆地发育过程,既包括断陷的初始发育期——火石岭期和强烈断陷期——沙河子期,也包括断陷的萎缩期——营城期,分别代表了深层断陷盆地的孕育、伸展裂陷和萎缩覆盖3个地质阶段。对断陷期地层的系统认识,使得深层烃源岩的评价预测更加有效可靠,对于深层油气勘探具有重大的指导意义。

Abstract:

According to the systematic seismic interpretation, three strata had developed during the faultdepression stage in the Songliao Basin. The developing processes and the original and present distributions of these three strata are very different. During the faultdepression stage, a complete forming process of a basin had happened, not only including the initial splitting phase—The Huoshiling Stage, and the dominating splitting phase—The Shahezi Stage, but also including the fading phase—The Yingcheng Stage. The systematic research on the strata during the faultdepression stage has led to the more accurate forecasting for the source rock, and is of great significance for the deep petroleum exploration.

Key words:

Songliao Basin; faultdepression stage; structural evolutional phase; petroleum exploration
