| 摘 要： | 营城组火山岩是松辽盆地北部大庆兴城深层天然气的主要储集体,天然气的富集主要受火山机构控制。火山机构由3个基本要素组成,即火山堆积高地、围斜构造和火山口,在地震剖面和水平切片上反射特征明显。本文通过大量地震剖面和水平切片的研究,从火山机构的外部形态、内部结构及其与上叠沉积层的接触关系入手,归纳总结出火山机构的14种地震反射特征,进而在兴城南部营城组识别出15个火山机构。地下火山机构的识别与研究对于松了盆地深层天然气勘探开发具有重要的指导意义。

| Abstract: | Volcanic rocks of the Yingcheng Formation in Xingcheng area are mainly deep gas reservoirs. The accumulation of deep gas is controlled by the volcanic apparatus, which consists of 3 elements: volcanic plateau, pericline and crater, all having clear seismic reflective characteristics. Based on the study of seismic sections and seiscrop sections, the authors summarized 14 kinds of seismic reflective characteristics, which represent the external appearance and internal structure of the volcanic apparatus as well as the contact relationship between the volcanic rocks and their overlying sedimentary formations. 15 volcanic apparatuses were recognized through the study of these 14 seismic reflective characteristics, which is of great significance in guiding the exploration and development of gas fields. |
