Experimental device and method for completion string vibration deforming under actual situation

The invention relates to an experimental device and method for completion string vibration deforming under an actual situation. The experimental device comprises an air compressor, a buffer tank, a pressure adjusting valve, a pressure gauge, a flowmeter, a fixing plate, an inner pipe, an outer pipe, laser displacement sensors, a fixing clamp, a rack, a computer and a telescopic oil cylinder; airflow generated by the air compressor is adjusted through the buffer tank and the pressure adjusting valve and then passes through the inner pipe to make the airflow have the air pressure and air volumesimilar to those of gas collected under the actual situation; and the laser displacement sensors collect data of inner pipe vibrating and then deforming caused when the airflow flows through the innerpipe, and then the data are displayed on the computer to be collected. The experimental device and method have the advantages that inclined shafts at multiple angles can be simulated, safety and reliability are achieved, oper
