Abstract: Starting from the characteristics of oil and gas enterprises and financial risks against the background of the global financial crisis，we systematically study the financial earlywarning indices，which include financial and nonfinancial indices.After comparing several classic financial earlywarning models，and taking relative membership grade instead of absolute membership grade，we propose the comprehensive judgments model of oil and gas enterprises，the weights of which relate to the criteria determined by AHP combined with entropy weights.Finally，we take a gas field as an example and apply the constructed financial warning model to practice.The result shows the possibility of financial crisis is on the rise in general.This model is hoped to enhance the financial earlywarning capability of oil enterprises and therefore improve their fiancial mangement.
