To address the problems existing in testing steam injection profiles in a steam-stimulated well during steam injection and production periods,this paper proposes that the temperature profile in the completion interval could be tested during the soak period. A mathematical model for calculating the vertical distribution of temperature in a single layer reservoir is established based on the temperature characteristics of steam stimulated reservoirs,and the vertical distribution of temperature in a single layer reservoir could be obtained and heat loss could be calculated. The temperature,which is disturbed by thermal conduction in a multilayer reservoir,and heat loss could be derived based on the superposition principle of temperature potential. This paper establishes a multilayer testing temperature profile interpretation method and interprets the actual test temperature profile of Well Gao 3-7-66. The results indicate that the temperature profile in the soak period can reflect the thermal absorption conditions in various reservoir beds.
