Claim 5:
6. The method for acquiring logging parameters according to claim 2, wherein the logging parameters further comprise gas saturations of different formations; and
the method further comprises: for different formations, calculating the gas saturation of each formation respectively according to the calculated gas-bearing porosity of the formation and all contour values in a two-dimensional nuclear magnetic D-T2 graph corresponding to the formation,
wherein calculating the gas saturation of each formation respectively according to the calculated gas-bearing porosity of the formation and all the contour values in the two-dimensional nuclear magnetic D-T2 graph corresponding to the formation comprises:
taking a result of dividing the gas-bearing porosity of the formation by a sum of all the contour values in the two-dimensional nuclear magnetic D-T2 graph corresponding to the formation as the gas saturation of the formation.
