In the study of plane heterogeneity, the homogeneity in (1 + 2) 4 (1) depositional unit was the best, while the homogeneity of 42 (2) depositional unit was the worst in upper ng of Chengdao Oilfield.

在平面非均质性研究中，馆陶组上段(1 + 2)4(1)沉积单元均质性在埕岛油田馆陶组上段中是最好的，而42(2)沉积单元均质性是最差的。

According to the seismic waveform theories, the seismic facies have been identified and divided automatically and the plane distribution of the depositional systems have also been determined.

依据地震波波形理论，进行地震相自动识别、划分，可确定沉积体系平面分布特征。
