In view of the traditional internal revenue rate parameter condition change, need to adjust the data to restore, And the lack of historical data cannot be used, or corporate managers do not pay attention to the situation of historical income, The internal rate of return index based on the residual evaluation period of pipeline project is proposed, and combined with the actual operation of oil and gas transmission pipeline, Respectively constructed an evaluation model of two cases of equilibrium and non equilibrium of cash flow in operation period, calculated and analyzed the corresponding relationship between the internal rate of return of different residual evaluation period and basic yield of the whole evaluation period. Finally for a pipeline enterprise 3 pipeline were calculation, the measured results were analyzed and evaluated.
