The invention provides an oil-gas-water-solid multiphase separation technology and multiphase separation device. Oil-gas-water-solid separation is achieved by means of three-stage separation, hydrocyclone separation, settling separation, air floatation treatment and the like of separation tubes. The device comprises a first-stage separation tube, a second-stage separation tube, a solid-liquid separator, a third-stage separation tube, a hydrocyclone, a settling tube and an air floatation tank which are in connection in sequence. According to the technology and device, rapid oil-gas-water-solid separation is achieved by means of the tube characteristics, the density differences among every phase medium and dynamic separation, a traditional method that multiphase separation can only be achieved with the help of containers is broken through, and a blast failure mode of the pressure containers is converted to a leakage failure mode of the pressure tubes, so that equipment security management risks are greatly lowe
