Abstract

The primary source rock of Yabei Sag was coal measures of Yacheng Formation in Oligocene and its distribution was controlled by sedimentary facies.According to the analysis of regional geological setting,paleontology,lithology assemblage,tectonic feature,paleo-topography etc,the sedimentary facies of Yacheng Formation are mainly tidal flat,lagoon and partly fan-delta.The tidal flat grows on the place where the slope is gentle and the topography is broad.Sporopollen analysis showed that there were a lot of mangrove trees in Yabei Sag during the period,which could form coal after death.The relative closed hydrodynamic condition in the sag is favorable for the formation of coal measures.Therefore,tidal flat bears favorable conditions for the formation,accumulation and preservation of coal measures and is a favorable sedimentary facies belt for the development of coal measures source rocks.Tidal flat in the Yabei Sag is mainly developed in the south and southeast gentle slope.Yacheng Formation in the southeast gentle slope has greater burial depth and higher thermal maturation of organic matter,indicating the formation of oil and gas.
