Abstract:
Compatible with the characteristic of Mesozoic reservoir in Chuanxi sag.the principle,method and advantages of NMR are provided with examples of application.The meth- od compensates conventional logging data for the shortages as whether the reservoirs contain bound water,how much the volume of the bound water is and how many the permea- bility is.The NMR log is superior in the accurate calculation of porosity and permeability,and the classification of pro- duction horizon,dry layer and water yield layer,thus enhan- cing the precision of logging interpretation of the Mesozoic gas sandstone in Chuanxi Basin.
