摘要

松辽盆地东南隆起区深部下白垩统存在地层重复的问题。九台县的三台乡、官马山地表剖面以及盆地内部的地震剖面上

管城酸性火山岩侵位于沙河子组之中

而不是夹层关系。所谓营城煤系就是沙河子组。火石岭组也存在同样问题。因此

本区早白垩世成盆期只有一个沙河子组

它与中央坳陷区的敖包组、登娄库组大体相当。据此

敖包组、登娄库组极有可能是中央坳陷区深部重要的径源岩

因而是一个有远景的含油气区。

Abstract

Stratigraphic repetation exists in deep-seated lower Cretaceous Series inthe southeast rise of the Songliao Basin.The acid volcanic rocks of the Yingcheng Formation intrude the Shahezi Formation instead of intercalation.This kind of intrusion can be seen on both surface profiles and seismic profiles in Santai

Guanmashan-Huihuiying areas in Jiutai County.The Yingcheng coal-measures as were called before is acturally the Shahezi Formation.It thus conclude that there was only Shahezi Formation in the study area in Early Cretaceous basining period which corresponds with the Aobao and Denglouku Formations in central depression.According to the above mentioned

the Aobao and Denglouku Formations may possibly be the most important deep-seated hydrocarbon source beds in the central depression of the Songliao Basin.
