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.

应用层序地层学基本理论，在综合分析工区地震、测井、岩心等资料的基础上，确立了超层序界面、准层序和准层序组识别标志，进而对松辽盆地北部升平地区深层进行超层序界面识别，共识别出五个超层序界面，分别为基岩顶面(SSB1)、沙河子组底面(SSB2)、营城组底面(SSB3)、登娄库组底面(SSB4)和泉头组底面(SSB5)。

The velocities of ultrasonic wave and rock drillability are measured in perpendicular and parallel directions of the bedding plane of core samples which were cut from the approach hole of Chinese continental scientific drilling. Rock drillability index and P-wave velocity anisotropy coefficient are calculated from the testing data; and the results are discussed.
