Abstract：In the logging technology,gas logging is an important method for reservoir evaluation,gas logging technology in-clude Kessler hydrocarbon ratio method and triangle plate method. However,according to the theory of experience to select the val-ue point,value point error will be generated. Therefore,cubic spline interpolation method is proposed to select the value area of in-terpretation plate,the method is applied to reservoir evaluation. Cubic spline interpolation method is studied to calculate the value point,the theory and method of gas logging technology are studied. The value area obtained by the cubic spline interpolation method is used in triangle chart of gas logging technology,this can improve the accuracy of recognition of oil and gas reservoirs.
