It is theoretically considered that reservoir gas-bearing makes interval transit time porosity and density porosity increase and neutron porosity decrease.

理论上认为，储层含气使声波时差孔隙度和密度孔隙度增大，使中子孔隙度减少。

There is a certain functional relation between seismic interval velocity and formation porosity as well as residual porosity.

地震层速度与地层孔隙度、剩余孔隙度之间存在一定的函数关系。

To certain extent, therefore, the thickness of the oil-bearing interval as well as the volume and permeability of the fracture porosity are also influenced by principal curvatures.

因而油层厚度及与之有关的裂缝孔隙体积和渗透率也在一定程度上受到构造面主曲率的影响。
