Pipeline cleaning cleanliness full-pipeline detection method and device

The invention discloses a pipeline cleaning cleanliness full-pipeline detection method and device, and relates to the technical field of oil and gas pipeline treatment. Specifically, the detection method comprises the following steps: the cleanliness of a pipeline is calculated according to the obtained mass difference of a first detection piece and a second detection piece before and after the first detection piece and the second detection piece pass through the pipeline; the first detection piece and the second detection piece are both in full contact with the inner wall of the pipeline, theinterference rate is 1%-7%, the first detection piece is made of a water and oil absorption material, and the second detection piece is made of a hard material. According to the detection method, thepipeline cleaning cleanliness can be accurately calculated, numerical quantification of the pipeline cleaning cleanliness is achieved, and the detection method has the advantages of being high in detection stability and good
