The invention discloses a method for determining a leakage position of an oil gas gathering and transferring pipeline, and belongs to the technical field of engineering automation of an oil gas field.According to the method for determining the leakage position of the oil gas gathering and transferring pipeline, negative-pressure wave signals of a first station and a last station and potential distribution curves of a plurality of cathode protection potentials on the oil gas gathering and transferring pipeline are obtained; a first leakage range and a second leakage range are determined; and athird leakage range is determined according to the first leakage range and the second leakage range, so that a constructor can determine the leakage position of the oil gas gathering and transferringpipeline directly according to the third leakage range. The negative pressure wave technology and the cathode protection potential technology are combined, so that accurate determination of the leakage position of the oil gas
