The invention provides an oil-gas-water-solid multi-phase separating method and a separating system. The oil-gas-water-solid multi-phase separating system comprises a first-grade gas-liquid separator, a first-grade separating tube, a liquid-solid hydro-cyclone, a second-grade gas-liquid separator, a second-grade separating tube, a settling tube and a liquid storage pot. Fast separation is achieved by using tube characteristics, the density difference of oil-gas-water-solid media and dynamic separation, traditional multi-phase separation achieved by containers is broken through, and the explosion failure mode of a pressure container is translated into the leakage failure mode of a pressure tube, so that equipment safety management risks are greatly reduced. The separating tubes are composed of horizontal tubes and vertical tubes in the process, and liquid-solid separation adopts traditional liquid-solid separating equipment. The separating device can completely replace traditional three-phase separating equipm
