在地质勘探中,需要对深部地层储层参数进行反演,也就是根据观测到的一些基础地球物理数据,来反推岩石地层的物理参数,比如孔隙度、渗透率、饱和度等。了解这些岩石物理常量有助于科研人员对地下地质构造有一个充分的了解,为寻找天然气石油储藏,或者是构造分析提供理论基础。 In geological prospecting, reservoir parameters of deep strata need to be inverted, that is, the physical parameters of lithosphere, such as porosity, permeability and saturation, are deduced based on the observed basic geophysical data. Understanding these petrophysical constants helps researchers have a good understanding of subsurface geological formations and provides a theoretical basis for finding natural gas reservoirs or for structural analysis.
