【摘要】 与致密的单相地质体相比,当地质体中含流体如油、气或水时,会引起地震波能量的衰减;通过提取反映地震波能量衰减快慢的属性就能在一定程度上预测地下的流体,这种属性体可以作为烃类检测因子.柴达木盆地第四系生物气藏分布范围广,勘探潜力巨大.为了更深入对柴达木盆地天然气藏进行预测研究,对本工区11条测线的纯波数据进行了衰减属性分析研究,效果非常好.为预测柴达木盆地第四系天然气藏提供了实际参考和理论依据.更多还原

【Abstract】 The seismic wave energy decrease when the fluid exist such as oil,gas or water.So we can estimate the hydrocarbon exist whether or not from it.Here we use three basical seismic attribute which indicate the attenuation degree of seismic energy.The gas reservoir in Qaidam basin has wide foreground.In order to predicate the gas reservior,attenuation attribute anlaysis has been done over the seismic data of Qaidam.The predicate result is satisfactory.It is good to predicate the Gas reservor practically and theoretically.更多还原
