摘要
地震反演是利用地震资料,以已知地质规律和钻井、测井资料为约束条件对地下岩层空间结构和物理性质进行成像(求解)的过程。结合研究区地震资料及测井资料中的构造、层位及岩性信息,推导出目的层的波阻抗、密度、速度、孔隙度、渗透率以及压力等信息,为储层优选提供更多依据。
Seismic inversion is a process of imaging(solving)the spatial structure and physical properties of underground strata by using seismic data,taking known geological rules and drilling and logging data as constraints.Combining with the structure,horizon and lithology information of seismic data and logging data in the study area,the information of wave impedance,density,velocity,porosity,permeability and pressure of the target formation are deduced,which provides more basis for reservoir optimization.
