Application of Amplitude Information to Yonganchang Structure in South Sichuan
Lin Kaishi;Zhou Changlun
The difference of the vertical positions of gas-bearing fractured zones will make the seismic amplitude changed complexly in the carbonate rocks of Yangxin Series. Perrnian. in South Sichuan. Picking up the amplitude anomalies with various types may predict the spacial distribution of gas-bearing fractured zones. A conformability check on predicting fractured zones by use of the drilling data gained from Yonganchang Structure has proved that this method is feasiblc.
