This invention provides a method for interpreting conventional well tests in complex reservoirs. The method includes considering permeability variations near the wellbore in a complex region, analyzing pressure recovery curves, calculating the flow coefficient based on shut-in time and bottom-hole pressure in each zone, analyzing the variation trend of reservoir properties around the well based on changes in the flow coefficient, calculating reservoir permeability at different time intervals, amplifying the time interval data to observe the relationship between reservoir properties and time intervals, and obtaining the wellbore reservoir coefficient based on the pressure recovery theory, considering the changes in bottom-hole pressure over time based on shut-in time and time. The method also calculates the pressure recovery rise value based on the wellbore reservoir coefficient and when the test data time intervals are the same. This invention is suitable for reservoirs with water injection, polymer injection, alternating gas and water injection, wellbore contamination, or improved permeability near the wellbore, and is also applicable to the interpretation of well test data from reservoirs with varying rock properties.
