gas-bearing porosity

基本解释

The difference of the porosity-calculated from sonic log and from neutron log is related to the effect of CO2 in gas-bearing beds.
用声波时差计算总孔隙度中t与计算出的中子孔隙度中。对比，其差值就是CO：的影响所致。
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。
NMR Logging can provide accurate values of irreducible liquid, movable liquid, effective porosity and permeability, and also identify the tight zone, water zone and gas-bearing zone.
核磁共振测井可以准确地提供地层的自由流体体积和束缚流体体积、有效孔隙度及其渗透率，能较好地判断干层、水层及气层。
