基于子波分解的含气性识别技术在cc地区浅层气藏勘探中的应用
Keywords: 子波分解,含气性识别,频谱异常,低频共振,高频吸收衰减
Abstract:
？利用子波分解技术将常规地震数据道分解成不同频率子波的集合,并以此为基础开展基于频谱异常的储层含气性检测。cc地区目的层——沙溪庙组以一套河流—三角洲沉积为主,砂体单层厚度不大,多在20m左右,且同一河道的不同位置以及相同位置的不同河道,其储层含气性迥异。基于传统地震数据的频谱分析由于受其分析时窗限制,其抗噪性和稳定性差,难以准确识别其含气性。为了能准确预测该地区不同期次,不同位置河道砂体的含气性,将基于子波分解的含气性识别技术加以应用,通过分析其得到的频谱异常发现,该地区含气河道砂岩具有明显的“低频共振,高频吸收衰减”特征,利用该特征不但能清晰区分当前高产井与干井,而且成为后期井位部署的主要依据。[jp]
