本文主要针对庆深气田A区块火山机构进行研究,庆深气田A区块主力产气层为营城组火山岩储层,火山岩储层主要受火山机构的发育情况和火山岩相带展布形态控制,如能准确的识别火山机构就能准确的解读火山岩储层,对以后的勘探和开发都有重要的意义。本文主要从研究区的单井资料出发,收集区域地震资料,应用单井优势相分析、相干体技术和构造趋势面技术等多种技术手段相结合,识别出庆深气田A区块所有的火山机构。为庆深气田的稳产、增产提供可借鉴的地质依据。
In this paper, we mainly study the volcanic structures of block A of Qinshen gas field. The main gas-bearing layer of Block A of Qing-Shen gas field is the Yingcheng Formation volcanic reservoir. The volcanic reservoir is mainly controlled by the volcano body’s development and volcanic facies belt spreading pattern If we can accurately identify volcanic structures, we can accurately interpret volcanic reservoirs, which is of great significance to future exploration and development. Based on the single well data in the study area, the paper collects regional seismic data, and uses the single-well dominant phase analysis, coherence body technology and tectonic trend surface technology and other technical means to identify all the volcanoes in Block A of the Qing-Sheng Gas Field mechanism. It can provide the geological basis for the steady and yield increase of Qing-Shen gas field.
