The invention provides a system and method for recovering volatile organic compounds at gathering and transportation filed stations. The system comprises an oil storage tank and a breather valve at the top of the oil storage tank, and further comprises a pored pipeline, an electric valve and a gas storage tank, wherein a communicating pipeline is arranged between the breather valve of the oil storage tank and the gas storage tank, the electric valve is arranged on the communicating pipeline, one end of the pored pipeline is connected with the electric valve, the other end of the pored pipelineis sealed, at least one circle of the pored pipeline is provided with air holes in the circumferential direction, a pressure gauge is arranged on the gas storage tank, and a gas outlet pipeline of the gas storage tank is connected with a one-way valve and a gas suction pump; and a sleeve sleeves the pored pipeline, and the sleeve can move in the axial direction of the pored pipeline. According tothe system and method for recovering the volatile organic compounds at the gathering and transportation stations, the pored pipeline is adopted to prevent the oil storage tank or the electric valve from deforming due to negative pressure suction when the gas is sucked by the gas suction pump; and meanwhile, the escape of the volatile organic compounds is avoided through the sleeve, and in the recovering process, an electric control cabinet is used for controlling the electric valve, the gas suction pump and a motor to be started, so that the automatic recovery of the volatile organic compounds is realized, and the requirements for clean and environment-friendly production in an oil field on-site oil field oil collecting station and a combined station are met.
