基于高分辨率层序地层学分析的岩相古地理编图结果非常清晰地显示了研究区长6段砂体展布特征，同时通过古盐度恢复，首次确定了该区湖岸线的位置，从而确定研究区主要发育三角洲前缘亚相，三角洲平原只在东北一隅有小范围分布。

We have taked sedimentary facies research on the second member of Shanxi formation of Changbei gas field, this area pertained to marine facies braid river delta sedimentary system, we have gived a detailed discriiption on different subfacies, microfacies, sandbody's sedimentary character and distribution for the braid river delta sedimentary system.

对长北气田山2段开展了精细沉积相研究，确定该地区山2段属于海相辫状河三角洲沉积体系，并对该三角洲沉积体系的各亚相、微相和砂体展布特征与演化规律进行了详细研究，建立了自北向南延伸的辫状河三角洲沉积模式。2。

On the basis of comprehensive discipline research, the rocks subfacies and microfacies of hydrothermal rocks facies have been initially studied and the their characteristic have been come to conclusions frist time.

在多学科综合研究基础上，首次系统提出研究并总结了热水沉积岩相的亚相及微相特征，亚相包括有：钠长岩-似碧玉岩亚相、硅质白云岩→硅质岩亚相、碱性钠长石质-碳酸质岩亚相、铁镁碳酸盐岩亚相、重晶石岩亚相、黑云母方柱石岩/黑云母岩亚相及铁绿泥石岩亚相。

In application, the first coarse seismic facies classification effectively identified the channel, erevasse-splay, natural levee, alluvial flat and other subfacies etc, and the second fine reclassification aimed to the classified channel further identified the lateral bar, mid-channel bar, main channel sand body and other microfacies of a fluvial channel.

通过实际应用指出，初次的相对较粗的地震相分类研究可以有效地区分出了河道、决口扇、天然堤、河漫滩等沉积亚相，而针对刻画出的河道的再次地震相分类研究则可以有效地区分出了边滩、心滩和主河道砂体等沉积微相，并初步证实了地震相再分类研究在客观刻画地质体细节方面的优势。

Upper and middle Silurian formations are denuded in Tahe area, only lower Silurian Kepingtage Fomation and Tata' ai' ertage Formation develop here with 2 sedimentary subfacies which are tidal flat and continental shelf, and 3 microfacies which are mixed flat, sand flat, and continental shelf mud.

塔河地区志留系缺失中、上统，只保留了下统柯坪塔格组及塔塔埃尔塔格组，发育滨海－浅海碎屑岩沉积，包括潮坪、陆棚等沉积亚相和中潮坪、低潮坪、陆棚泥等3个微相。
