Abstract: Through theoretical analysis,combining with the actual well temperature,this paper summed up integrated interpretation of fracture height with the application of temperature curve and logging time. This method comprehensively considered the temperature curve,wellbore pressure and loggingtime,proposed to obtain temperature data at different time,which used curve demi point,change point of the temperature curve gradient,change point of the temperature curve gradient direction ,inflection point of and the temperaturecurve rising from the lower to determine crack borders,and improve the adaptability of fracture height interpretation.
