Big Data is not a fashionable concept in oil and gas pipeline industrial, but a real technology. Introduced is the generation and management model of Big Data in pipeline route block valve stations and process stations and discussed is the correlativity between different data obtained through analyzing destroyed equipment on site by using Big Data in combination with accident cases. Conducted are customization and modification, function extension and repeated data development and utilization of the generated history server in order to forecast accidents in future. Oil and gas pipelines has been net worked, diversified and intensive and application of Big Data will not add any additional investment, but also can effectively assure safe and smooth operation of oil and gas pipelines.
