Application of identification,seismic reservoir prediction technology in channel 4th Memher of Triassic Akekule Formation sandbody Oil Field

The lithologic traps of T₂a⁴ are important for production in the Tahe Oil Field.During theearly stage,structural traps were focused on in the Triassic formation.As explorations expanded,It haSbecome more and more difficult to find structural traps.So,it is necessary to look for lithologic trapsand reservoirs.Technological methods such as 3D seismic interpretation,comprehensive analysis ofproperties,spectrum analysis and impedance inversion have been used in the T₂a⁴ reservoirs.The than-nel sandbody of TZa has been distinguished and described,which may guide the deployment and imple-mentation of development wells.The studies contribute to the production increasing in the Tahe OilField and provide valuable experience for litholo}ic traps searching.
