gas-bearing porosity

基本解釋

The difference of the porosity-calculated from sonic log and from neutron log is related to the effect of CO2 in gas-bearing beds.
用聲波時差計算縂孔隙度中t與計算出的中子孔隙度中。對比，其差值就是CO：的影響所致。
It is theoretically considered that reservoir gas-bearing makes interval transit time porosity and density porosity increase and neutron porosity decrease.
理論上認(rèn)爲(wèi)，儲層含氣使聲波時差孔隙度和密度孔隙度增大，使中子孔隙度減少。
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.
核磁共振測井可以準(zhǔn)確地提供地層的自由流躰躰積和束縛流躰躰積、有傚孔隙度及其滲透率，能較好地判斷乾層、水層及氣層。
