Stratigraphic distribution of complex buried hill and its significance in the Yingmaili aera
英买力地区复合潜山的地层分布及意义

In order to determine the stratigraphic distribution of a complex buried hill composed of different rocks, subtly structure elucidation is made on the condition of complex tectonic setting based on technology of seismic facies analysis and seismic muti-attribute clustering. It is very important to know stratigraphic distribution along the Cretaceous bottom, especially Jurassic distribution leads to the breakage of buried hill hydrocarbon reservoir. Then revervoir distribution of the complex buried hill is predicted by use of the seismic muti-attribute clustering analysis method. The results obtained suggest that favorable reservoir is distributed on the upper Cambrian dolomite buried hill and lower Ordovican grey matter dolomite buried hill north of the Ym7 well, as well as bitumen-bearing sandstone member in the Kepingtage formation of Silurian.
