摘要(Abstract)：

介绍了反射系数计算方法； 阐述了松辽盆地北部Ｔ３ 反射系数分布规律， 分析了Ｔ３ 反射层特征的成因， 认为岩性岩相变化、埋藏较深、Ｔ２ 反射层屏蔽以及较小的波阻抗差是影响Ｔ３ 反射层特征的主要因素。
This paper introduces the calculation method of reflection coefficient and the distribution rule of T\-3 reflection coefficient of north Songliao Basin, and analyses the genesis of the characteristic of T\-3 reflection horizon. It suggests that the main factors affecting the T\-3 reflection horizon characteristic includes lithological and facies changes, deep burial, T\-2 reflection horizon screening and little wave impedence difference.
