Based on seismic, well logging, drilling and core data, five super sequence boundaries have been identified by using methods of sequence stratigrphy theory in deep formations of Shengping area, northern part of Songliao basion. They are the top boundaries of bed rock (SSB1), the bottom boundaries of Shahezi group (SSB2), the bottom boundaries of Yingcheng group (SSB3), the bottom boundaries of Denglouku group (SSB4) and the bottom boundaries of Quantou group (SSB5) respectively.

The study shows that in the radial direction the dynamic forces acting on the particle balance on the particle itself; there is not a so-called trajectory of the particle in which the composition of forces acting on the particles is zero, but there is a trajectory of the particle in which the radial slip velocity of particle is zero, the tra...

通过对固体颗粒的运动和受力分析发现固体颗粒在沉降过程中径向合力几乎处处为零，不存在所谓的径向合力为零的一个平衡轨迹面，但存在着一个径向沉降速度为零的轨迹面，这一轨迹面就是平衡轨迹面法所要寻找的；首次推导出了该轨迹面半径与固体颗粒直径、水力旋流器自身几何参数以及操作参数之间的定量表达式。
