Abstract

Summary

Seismic trace integration is a helpful seismic attribute, which is also called the relative wave impedance. Although previous researchers have discussed and applied this technique in sandstone reservoir description, quantitative analysis and research are still few. As a case of thin channel sand body in Dong 7 well area, the composite wave and integration trace of the single layer response is quantitatively analyzed at first. Then a pinch-out wedge model is made and the advantage is shown in variable density interpretation. For this wedge model, the predicting thickness by trace integration and tuning thickness method is compared. Finally, the technology is applied to whole well block. The characteristic is described visually and the sand range is predicted precisely.
