Abstract：The Cretaceous K1g1 Reservoirs in Yaerxia are lithology-structural reservoirs,in which faults are well-developed and structures are complicated.Reservoirs of this area have dissolvable porosity type with high heterogeneity.So it is very difficult to predict these reservoirs.From the seismic attri-butes approaches provided by GeoEast System,some sensitive ones such as coherence and curvature,are optimized for structure interpretation,reservoir prediction,fault system identification,and fracture classified.Other seismic attributes such as root-mean-square amplitude and highlight volume are used to predict favorable channel sand distributions,sand thickness,and fluide activity.Both structure interpretation and reservoir prediction are achievdbased on well logging and seismic data.The drilling depoyed on our reseach makes great success.
