摘　　要：碳酸盐岩潜山由于经历了长期的风化剥蚀,岩溶储集体非常发育,而火成岩体(侵入岩和喷发岩)的发育,导致碳酸盐岩潜山进一步复杂化。由于火成岩的地震响应特征与岩溶的地震响应特征在许多方面有相似之处,使得对碳酸盐岩岩溶型储集体的识别和预测更加困难。为了对碳酸盐岩潜山发育的火成岩进行识别和预测,本文通过对典型地区的岩溶型储集体、火成岩体的地震反射特征进行比较研究,建立了四种火成岩地震相模式,并总结出了一套利用地震相干、沿层地震属性特征与地震剖面的地震相特征相结合的方法。将该套方法用于塔里木盆地塔北英买力地区碳酸盐岩潜山的火成岩识别和预测,取得了良好的效果。Since experienced a long period of weathering and erosion,developed karst reservoir in carbonate buried hill,development of igneous rocks (intrusive rock and extrusive rock) made the carbonate buried hill more complicated. Since there are many similarities in the characters of seismic response between igneous rocks and karst, which makes the identification and prediction of carbonate karst reservoir more difficult. In order to carry out identification and prediction of igneous rocks developed in carbonate buried hill, the paper created four modes of igneous seismic facies by correlation and study of seismic reflection feature of karst reservoir and igneous rocks, and summed up a set of methods combing seismic coherent character, the character of seismic attributes along the horizons with the feature of seismic facies on seismic sections. It was achieved good effects by using the methods for identification and prediction of igneous rocks in carbonate buried hill of Yinmaili area, Tabei of Tarim basin.
