摘要(Abstract)：

转换波分裂裂缝检测是多波多分量地震勘探的重要价值所在.根据转换波分裂的特点和信息,可以预测裂缝的发育方位和密度.在裂缝油气藏中,这2个参数对提高油气采集率具有重要意义.当研究的目标层以上的盖层中,存在不只一个含裂缝各向异性层时,转换波就会发生多次分裂,上覆各向异性对下层裂缝参数的计算具有较大影响,因此必须估算并补偿分裂的快慢波时差,消去盖层各向异性的影响,以获得更准确的目标层的裂缝信息.通过理论模型正演及实际资料计算分析,研究多层裂缝介质中转换波传播特征及分裂机制,分析转换波R,T分量在多层裂缝各向异性介质中的分裂特征,利用能量比法预测裂缝方位,估算快慢波时差,并做层剥离时差补偿后,提高计算精度.
