Seismic reflection characteristics research on Ordovician reef flat reservoirs of Tazhong area

The reef flat reservoirs of Lianglitage formation in Tazhong area are of a variety of reflection characteristics,mainly behaving as strong beaded reflection,weak beaded reflection and weak surface reflection.These different seismic response characteristics represent different reservoirs types and reservoir development patterns.Through the application of seismic facies analysis,seismic attribute analysis,seismic inversion,and other techniques,the plane distribution of the reef flat facies reservoirs in this area have been predicted.Combined with Ordovician palaeogeomorphology of Tazhong area,different reflection characteristics regularity of the reef flat reservoirs and its main controlling factors have been summarized,which provides guidance for future exploration and development in Tazhong area.
