Problems solved by technology
[0005] In order to solve the problem that the existing oil and gas field pipeline analysis method cannot accurately and comprehensively judge the failure cause of the pipeline, the present invention innovatively proposes an analysis method for the failure cause of the oil and gas field pipeline. A large amount of data related to the pipe body and the service environment of the pipeline can be obtained by means of testing, testing, etc., and the root cause of oil and gas field pipeline failure can be analyzed through real original data, effectively solving many problems in the existing technology, and providing oil and gas field pipeline protection, It provides sufficient data support to reduce the failure rate of pipelines and ensure the normal transportation of oil and gas and other media

Abstract
The invention discloses an analyzing method of failure cause of an oil and gas field pipeline. The method comprises the following steps: 1, viewing on site, and recording the pipe body information aswell as the pipeline service environment information; 2, testing data related to the inside of the pipeline and the failure position on site; 3, performing primary recognizing on the failure cause ofthe oil and gas field pipeline; and 4, performing second recognizing on the failure cause of the oil and gas field pipeline. The analyzing method is comprehensive, accurate, scientific, and easily mastered by on-site technician; the technical measures such as viewing the sites of the failure pipeline body and the service environment, sampling and testing are carried out, and the failure property of the oil and gas field pipeline is utilized, and on that basis, the purpose of correspondingly recognizing the failure cause of the oil and gas field pipeline is achieved; and important data basis isprovided for proposing economic and feasible protection measures, reducing the failure rate of the oil and gas field pipeline, and ensuring the normal production of oil and gas.
Description
technical field [0001] The invention relates to the technical field of pipeline transportation, and more specifically, the invention is an analysis method for failure causes of pipelines in oil and gas fields. Background technique [0002] At present, pipeline transportation has become the fifth largest mode of transportation after ocean transportation, railway transportation, air transportation and road transportation. It is becoming more and more important in national economic and social development, and it is especially suitable for the transportation of oil and gas and other media. However, with the extension of pipeline service time and the deterioration of the surrounding environment, there are more and more cases of pipeline failure. For example, the failure probability of pipelines in most oil and gas fields in my country is higher than 400 times / km / year, and failed pipelines seriously threaten personnel and public property security. [0003] However, due to the vari...
