The invention relates to the technical field of oil well pipeline infrastructure construction, in particular to a multi-pipe synchronous detection method for oil well gathering and transportation pipelines. The detection method includes the detection path adopting multi-pole grounding technology to ensure the detection signal strength, connecting the detection signal at the position of the Christmas tree at the wellhead of the oil well, synchronously adding the detection signal to the oil gathering, metering and water-mixed buried pipelines of the oil well, and then , combined application of AC current attenuation technology, audio leak detection technology, AC potential gradient detection technology and RTK measurement technology for multi-pipe synchronous detection. Sensitivity, and finally, sample excavation inspection and quality assessment based on ground inspection results. The multi-pipe synchronous detection method of the oil well collection and transportation pipeline provided by the invention improves the detection quality and work efficiency of the oil well collection and transportation pipeline, and reduces construction cost and labor intensity.
Description
technical field [0001] The invention relates to the technical field of oil well pipeline infrastructure construction, in particular to a multi-pipe synchronous detection method for oil well gathering and transportation pipelines. Background technique [0002] Oil well gathering and transportation pipelines are widely distributed in oil and gas fields. They are the main components of oil and gas field surface engineering. They are mainly composed of oil gathering, metering and water-mixing pipelines. They are usually laid in the same ditch with multiple pipes. According to the standard, the pipelines should be anti-corrosion after they are buried. Layer leak detection. The conventional detection method is to excavate the signal detection pit at the middle pipe section of the buried pipeline. The detection path adopts single-point grounding and near-pipe point signal access methods to apply the detection electrical signal to each pipeline respectively. Equipment such as leak ...
