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.

主要的研究包括：①根据桑塔木碳酸盐岩的储层特点，总结了该区的地震反射特征及油气分布特征；②研究出一种有针对性的地震属性--局域振幅横向差异性，来定量刻画潜山内部"短轴"杂乱反射能量团，预测缝洞型碳酸盐岩内部储层的平面分布规律；③通过对地震波形变化的分析，运用神经网络对地震波形进行有效分类，找出波形变化的总体规律，从而认识地震相的变化规律；④应用交会法地震多属性分析方法，对潜山表层和内部分别提取了5大类40种地震属性，通过一系列分析表层及内幕各自优选出3种、4种地震属性用于进行交会分析。
