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(shí)差計(jì)算總孔隙度中t與計(jì)算出的中子孔隙度中。對(duì)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)為，儲(chǔ)層含氣使聲波時(shí)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(cè)井可以準(zhǔn)確地提供地層的自由流體體積和束縛流體體積、有效孔隙度及其滲透率，能較好地判斷干層、水層及氣層。
