Abstract: The Chao yang gou oil field seismic data acquisition has been basically completed, as the development of the oilfield in recent years, the sand body in the Outside enlarge develop worse, urgently need to use the geophysical data and logging data to describe the tentonic characteristics and fault distribution of the research area. This way can enhance prediction accuracy of the fault and sand body. Build a set of Prediction method and train of thought to suit Chao yang gou oil field geological characteristics. This paper use the geological structure data and logging data to describe the reservoir characteristics of the research area. This paper has important significance for the guide the oilfield development adjustment.
