A sedimentary model is thus suggested for the upper member of the Hesan Formation on the basis of source area and its tectonic settings,in combination with well logs and geological data as well as the distribution of the seismic facies.

• 在明确研究区物源方向、物源区及其大地构造性质的基础上，综合利用研究区目的层段的钻井、测井及地质资料，根据其地震相平面展布特征，将地震相转换为沉积相，并由此归纳出研究区核三组上段的沉积模式。
