Deep hole ultrasonic imaging test method

The invention relates to the technical field of centralizer components, in particular to a deep hole ultrasonic imaging test method. The deep hole ultrasonic imaging test method comprises the following steps: step 1, sleeving at least one centralizer body on the outer wall of a probe tube; 2, pressing one side, facing the centralizer body, of the centralizing sheet, and compressing the spring until the diameter of the whole centralizer is smaller than that of the existing hole; thirdly, the exploring tube and the centralizer body are placed into an existing hole together; and step 4, inserting the probe tube into a set position to complete ultrasonic imaging test work. According to the deep hole ultrasonic imaging test method, the centralizer sheet and the spring are arranged between the outer wall of the centralizer body and the existing hole, so that the centralizer body and the exploring tube can be combined to adapt to the existing holes with more sizes, the practicability and the applicability of the cen
