| 摘 要： | AEJ地区地表大部分被沙漠、戈壁覆盖,目的层卡洛夫-牛津阶碳酸盐岩上覆的巨厚盐层对地震波高频成分能量系数比较严重,采用普通的反演不能有效地寻找储层和含气性敏感参数。为此在对研究区的测井资料和地震资料分析处理基础上,针对主要目的层的孔隙度变化、含流体变化进行叠前弹性参数反演研究,区内储层段表现为中低拉梅系数、中低剪切模量、中低泊松比、低纵波阻抗和低横波阻抗;泊松比的中低值对流体反映较敏感。利用叠前弹性参数反演,可以有效地进行流体识别。

| Abstract: | The surface of the AEJ area is mostly covered by desert and gobi.The exploration target in the Callovian-Oxfordian carbonates is overlain by very thick salt,cousing serious energy absorption of high-frequency component of seismic wave.The common inversion methods can't find reservoir and the gas-sensitive parameters.So on the base of analysis and process of log data and seismic data of the research area to prestack elastic parameter inversion study aim at porosity changing and fluid variation of the main ta... |
