Abstract Based on a study of deep volcanic gas-bearing reservoirs in Dongling area of Songliao Basin, this paper deals with the relationship between lithologic character and logging responses. ΔlgR and oil and gas recognition indexes were used to identify oil and gas, and a solidity model was set up to evaluate gas-bearing reservoirs. Porosity, saturation and other parameters were obtained, and the result was satisfactory.
