摘　　要：根据桑塔木潜山构造奥陶系风化壳储层岩性特征,总结了碳酸盐岩储层的地震反射特征,提取了相应的地震属性,应用交会法分析技术优选适当的地震属性进行储层缝洞预测,研究该区潜山油气藏缝洞发育带和储层的空间展布规律,综合其他研究预测了油气富集区,指出有利勘探目标。钻探表明,地震属性技术是该区有效的储层预测方法之一。Based on the lithologic features of Ordovician weathering crust reservoirs in Sangtamu buried hill structure, seismic reflection characteristics of carbonate reservoirs are summarized and the corresponding seismic attributes are extracted. Intersection analysis method is used to select appropriate seismic attributes for prediction of fissures and vugs in reservoirs. The spatial distributions of zones with well - developed fissures and vugs and reservoirs in the buried hill in this area are studied Oil and gas enrichment zones are predicted in combination with other study results and favorable exploration targets are selected. Drilling results verify that seismic attribute technology is one of the effective reservoir prediction methods in this area.
