Simulation experiment of gas saturation of Cretaceous sandstone in Kela 2 gas field, Talimu Basin;

Gas reservoir can be qualitatively identified with overlapping compensated neutron logs in cased well and uncased well,and with overlapping long-and short-spacing count rate of compensated neutron logs in cased well,further more,gas-bearing saturation can be quantitatively calculated by a "standard ratio of compensated neutron in cased well" derived from the count rates of long-and short-spacing.

Discussion on Computing Oil-Bearing Saturation from Fluorescence Intensity;

Taking the abroad NMR instrument as an exam ple, the author introduced the calculation formula for effective porosity, perme ability evaluation model, movable and irreducible fluid saturation, and effectiv e oil-bearing saturation.

A simplified calculating method is also presented based on oil-bearing saturation formula and experience formula.
