摘要
结合地震、测井和钻井等资料建立火成岩发育区碳酸盐岩地震地质模型,基于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组合的生物灰岩地震响应特征,如振幅、频率、相位等,为火成岩发育区碳酸盐岩储层的地震资料解释和储层预测提供理论指导。
The seismogeology models of the carbonate rock in the igneous province are established by the combination of the seismic data, logging information and drilling data. Based on the forward modeling of the wave equation, the stacked migration section is obtained by the traditional seismic data processing flows. The seismic response characteristics(amplitude, frequency and phase, etc) of the bioconstructed limestone with different form,different sedimentary facies and different combination of the reservoir are analyzed. The results will provide the guidance to the seismic data interpretation and reservoir prediction of the carbonate rock reservoir in the igneous province.
