深水礁滩相储层地震模型的正演模拟及其地震响应特征分析
|
摘要
结合地震、测井和钻井等资料建立深水环境下塔礁、台内点礁、跨相带碳酸盐岩地震地质模型,基于炮域波动方程正演模拟方法,应用常规地震资料处理流程获得叠偏剖面,分析不同形态、不同沉积相和不同储层孔隙条件的碳酸盐岩生物礁地震响应特征,如振幅、频率、相位等,为深水礁滩相储层的地震资料解释和储层预测提供理论指导。
Combining data from seism,logs and drilling,we establish the seismic and geological model of reef pinnacle,point reef intra platform,carbonate rock crossing facies in deepwater.Based on seismic wave field modeling on shot domain wave equation,stacked migration section is obtained through traditional seismic data processing.We also analyze the seismic response characteristic of biohermal carbonates with different forms,sedimentary facies,and different porosity,such as amplitude,frequency,and phase.Those analyses will provide guidance to the seismic data interpretation of deep water reef-flat reservoirs and reservoir prediction.
