摘　　要：火山旋回和期次是研究火山岩地层的基本单位,期次的确定能较好地解决辽河东部凹陷欧利坨子油田北部X35块沙三段火山岩地层划分与对比问题。通过岩心观察和描述,并利用录井、测井和地震资料,描述火山岩期次变化规律,揭示不同期次火山岩变化特征,建立火山岩岩相划分方法和分布模式,研究不同期次岩性及空间分布范围,为储层精细研究和井位部署指明方向。The cycle and stages of volcano are the study of the basic units of volcanic rocks stratum. The determination of stages can be helpful to solve the problems of division and correlation of the X 35 block of in Member 3 of Shahejie formation in the north of Oulituozi Oil field of the East Depression in Liaohe Basin. In this paper, through core observation and description, and use the logging, well logging and seismic data, the law of stage change of volcanic rocks are discribed, the characteristics of volcanic rock change in different stages are revealed, classification method and the distribution pattern are established, and the different stages and special distribution are described. The results can give beneficial directions to fine reservoir description and well placement.
