Summary: | The invention discloses a method and a device for evaluating the production condition of an oil reservoir of a heavy oil steam injection well. The method comprises the following steps: firstly, establishing a steam injection vertical well theoretical model; according to the steam suction amount of each perforation well section in the set steam injection vertical well theoretical model, calculating the theoretical temperature profile of each perforation well section after liquid production; when the error of fitting and comparing the theoretical temperature profile of each perforation well section after liquid production and the actually measured temperature profile of each perforation well section after liquid production is smaller than a preset numerical value, determining that the steam suction amount of each perforation well section in the set steam injection vertical well theoretical model is the actual steam suction amount of each perforation well section; calculating the heat absorption capacity percent |
