Application of Buried Pipelines External Inspection Technology in the Detection of the Oil-field Oil and Gas Gathering Pipelines

Buried pipelines are widely used in oil fields. With the running-time going longer,the bad operating environment,the equipment own ageing and other reasons lead to the pipeline-failures. That would cause a waste of resources,environmental pollution and social security threat. Using advanced external inspection technology for the buried pipelines detection and evaluation can be a maximum guarantee for the safety of oilfield production running. This article introduced in the application of buried pipelines external inspection technology in the detection of the oil-field oil/gas gathering pipelines,and summarize the main problems exist in the buried pipelines during the inspection process according the results of the detection and inspection data. The reasons affecting the safe running of buried pipelines are summarized and analysis. Then we provide appropriate recommendations and measures to provide technical support for the guidance in design and construction,day-to-day management and maintenance of buried pipelines in oil fields.
