1Based on the characteristics of carbonatite reservoir in Sangtamu area, we summarize the type of seismic reflection and the distribution of oil and gas.(2)Through the study of the lateral difference of local amplitude, which can predict the short, unorderly reflective energy gobbet of carbonatite reservior, we study the distribution of carbonatite reservoir with crack.(3)Analyzing the change of the seismic waveform, applying nerve network method to classify the seismic waveform, find the rule of its change, recognizing the change rule of seismic facies.(4)Applying the seismic multi-attribute cross method to study the surface and inner of carbonatite reservoir in buried hill. We first extract the 5 kinds of seismic attribute. Through a series of choices, we find those seismic attributes that are sensitive to the change of carbonatite reservoir.
