According to the oil pipe supporting device for intelligent separate-layer oil extraction and the using method thereof, through cooperative use of the cushioning mechanism, an anti-deposition mechanism, a flexible mechanism, a thermal compensation mechanism and other mechanisms, the problems that the supporting device vibrates unstably due to mechanical operation in an oil extraction area, an oil pipe is prone to being damaged at the connecting position of the oil pipe and the supporting device, and the heat expansion and cold contraction amount of the oil pipe cannot be effectively compensated are solved.
