| 摘 要： | 徐家围子断陷的主要产气层段为营城组火山岩段地层，所以研究该地层对寻找天然气藏具有非常重要的意义.本文利用丰乐地区的高分辨率地震资料、岩石物性资料、测井资料对下白垩统营城组火山岩进行构造精细解释，火山岩地震相及岩相分析从而进行储层预测，利用均方根振幅、瞬时频率能量及瞬时吸收系数能量等地震属性分析结合地震反演技术精细刻画火山岩储层.结果认为：均方根振幅、瞬时频率能量和瞬时吸收系数能量能较好预测火山岩相和储层物性；有利储层在反演剖面上表现为中低阻抗特征，中等密度；较好储层主要分布在工区的西部与中部.

| Abstract: | As the Yingcheng formation is an important gas producing formation in the Xujiaweizi fault depression,research on that formation has significant meaning.We have made fine structural interpretation and volcanic seismic facies and lithofacies analysis,and basing on that,we predict reservoirs of the Yingcheng formation of Lower Crataceous by using high resolution seismic data,analytical data of petrophysics and logging information.At the same time we use the advanced prediction method and technique to depict the reservoirs in volcanic rocks in detail.In the end,we conclude that amplitude-RMS,instant frequency energy and instant Q energy can preferably reflect lithology and physical propeviies of reservoirs.On inversion sections,beneficial reservoirs have low-to-moderate impedance and moderate density.Good reservoirs distribute mainlyin the west and middle of this area. |
