【摘要】 柴达木盆地三湖地区天然气勘探潜力巨大。为了更深入地对该盆地天然气藏进行预测,本文在分析该区天然气成藏后在地震剖面上表现特征基础上,着重应用频谱成像、衰减梯度分析、AVO、层间速度差分析(DI-VA)四种技术检测天然气藏。检测结果表明这四种检测技术均有良好的效果,可以排除烃类检测中的多解性和不确定性。更多还原

【Abstract】 There is a huge potential in natural gas exploration in Three-Lake area in Qaidam Basin.In order to further conduct prediction studies for the gas reservoir in the basin,the frequency spectrum imaging,the attenuation gradient analysis,the AVO and the DIVA were used to detect the gas reservoir based on the analysis of the characteristics presented on seismic sections by natural gas reservoir.The detection results show that all the 4 detection techniques above are effective,eliminating the ambiguity and uncertainty in the hydrocarbon detection.更多还原
