Problems solved by technology

[0004] However, the data collected by the indirect method generally has data uncertainties, such as measurement noise, transmission noise, sampling error, and there are observation blind spots, which make it impossible to intuitively detect the data of each point along the pipeline, which makes the measured data and standard theoretical analysis results often have l

Example Embodiment

[0015] The following will be combined with the accompanying drawings in the embodiments of the present specification, the technical solution in the embodiments of the present specification is clearly and completely described, it is clear that the embodiments described are only part of the embodiments of the present specification, not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art without doing creative work should fall within the scope of protection of this specification.

[0016] At present, the fault diagnosis of the transmission pipeline is mainly divided into direct method and indirect method. The direct method is to use human senses, such as direct observation, percussion, etc., or with the help of a special device, such as a pipeline robot to detect the pipeline and the environment in which the pipeline is located, so as to determine whether the pipeline is malfunctioning. The indirect met...

Abstract

The embodiment of the invention provides a conveying pipeline operation abnormity reason identification method and device. The method comprises the following steps: acquiring operation data of different positions of a conveying pipeline; clustering the operation data at different positions to obtain a preset number of operation data with different abnormal fluctuation types; labels are established for the preset number of operation data with different abnormal fluctuation types according to the corresponding relation between the abnormal fluctuation types and the abnormal reasons; the label is an abnormal reason corresponding to an abnormal fluctuation type occurring in the operation data; taking the operation data with the label as a training sample, and calculating a classification condition of the operation data in the training sample; and according to the classification condition, identifying the abnormal reason of the to-be-identified operation data, thereby improving the accuracy of identifying the abnormal reason of the operation of the conveying pipeline.

Description

technical field [0001] The embodiments of this specification relate to the technical field of petroleum transportation, and in particular to a method and device for identifying causes of abnormal operation of a transportation pipeline. Background technique [0002] With the development of oil and gas industry, pipeline transportation has become another important means of transportation after railway, highway, waterway and air transportation. Pipeline network transportation occupies an increasingly important position in the transportation of oil, natural gas and other fluids. Pipelines are used as carriers for the transmission of oil and other liquids, and are laid in various environments such as land and sea around the world; pipeline transportation is more convenient, but it is prone to damage during pipeline transportation, and oil pipelines will be damaged after long-term use If the oil pipeline leaks, it will not only cause major economic losses and environmental pollut...
