The embodiment of the invention discloses a gathering pipeline failure rate evaluation method and device. The method includes the steps of obtaining the historical failure rate of each failure mode ofeach type of pipeline; obtaining the pipeline type included in a target assessment pipeline; and obtaining the failure rate of each failure mode of the target assessment pipeline and the total failure rate of the target assessment pipeline according to the pipeline type in the target assessment pipeline and the historical failure rate of each failure mode of each type of pipeline. According to the gathering pipeline failure rate evaluation method and device, a failure rate assessment model is established based on historical failure data of a gathering system, so as to assess the target assessment pipeline according to the type of the target assessment pipeline. Compared with the prior art, the gathering pipeline failure rate evaluation method and device have the advantages of high assessment accuracy and high applicability.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of oil pipeline leakage early warning, and in particular to a method and device for evaluating the failure rate of a gathering and transportation pipeline. Background technique [0002] Oil and gas gathering and transportation pipelines are the link connecting various facilities in oil and gas fields. According to their transport media and functions, they are divided into oil outlet pipelines, gas production pipelines, oil collection and gas collection pipelines, oil transmission and gas transmission pipelines, etc. Compared with long-distance pipelines, the transportation terrain of gathering and transportation pipelines is complex, the soil properties vary widely, the pipeline structures are various, the properties of the transmission medium are different, and there are more overlapping and interlaced laying of multiple pipelines; some old oil fields such as Shengli and Daqing are ...
