摘要： 利用地震、测井解释技术,结合岩心资料,阐明了塔河地区火山岩岩性类型、地震相特征,并对火山岩成藏条件进行了分析。塔河地区二叠系火山岩发育英安岩与玄武岩两种类型。根据地震反射几何形态特征,划分为层状、丘状、透镜状和楔形4 种地震相。层状地震相分布广泛,主要对应于溢流相火山岩;透镜状地震相仅分布在盐边凹陷,其几何形态主要受盐体活动的控制;丘状地震相主要对应侵出相火山岩;楔形地震相的形成受基底裂隙的控制,侧向上与围岩接触,对应于近火山口相。丘状地震相和楔形地震相构造圈闭落实、储集层条件较好,为有利的油气勘探区域。

Abstract: Based on the interpretation of seismic data and logging, combined with core observation in Tahe area in Tarim basin, the types of volcanic rocks, seismic facies feature and volcanic reservoir-forming conditions are clarified and analyzed. Two types of volcanic rocks such as dacite and basalt of Permian and four seismic facies such as stratified, mound-shaped, lenticular and wedge-shaped ones occur in this area. The stratified seismic facies is in wide distribution, corresponding to the run-off volcanic rock; the lenticular seismic facies is only found in salt-edge sag, mainly controlled by the salt body activity; the mound-shaped seismic facies corresponds to intrusive volcanic rock; the wedge-shaped seismic facies is controlled by the basement fissure, laterally contacted with surrounding rocks, corresponding to near-crater facies; the mound- and wedge-shaped seismic facies are of effective traps and better reservoir conditions, being favorable areas for oil and gas exploration.

Key words: volcanic rock, seismic facies, volcanic facies, reservoir property, exploration potential
