The invention relates to the technical field of oil-gas field development, in particular to a well test interpretation method which comprises the following steps: establishing a well test model of a target fault-solution reservoir; according to the well testing model, a real space well bottom pressure solution is obtained; based on a real space bottom hole pressure solution, drawing a theoretical double logarithmic curve of a test well in a real space; fitting the actually measured double logarithmic curve of the well test with the theoretical double logarithmic curve to obtain well test interpretation parameters of the target fault-karst reservoir; the method can describe the external contour and the internal structure of the fault-karst reservoir, describe the distribution of multiple holes in the fault-karst reservoir, accurately understand the internal characteristics of the fault-karst reservoir, find large-scale reservoir bodies, describe fracture-cavity units and obtain reservoir parameter results, and
