The Research Of Pipeline Hydraulic And Water Hammer Protection Under Custody Transferation

In recent years, the rapid development of domestic oil pipeline construction, pipeline construction has brought rapid development of the national economy, but also to the construction of oil has brought vitality and development. Research custody transfer technology for long-distance pipeline custody transfer Liaohe oilfield construction system is a new project, to carry out long-distance pipeline is a very important practical significance, not only to fill the gaps in our ability to improve the design of pipeline construction, make history, but also can improve the vitality of the global production infrastructure systems.In this paper, the development of pipeline technology, a brief introduction, briefly describes the technical difficulties and trends facing engineering applications. And studied the following techniques:Mainly on the practical engineering of hydraulic oil pipeline in state custody transfer are analyzed, to elaborate on the advantages and technical difficulties custody transfer mode. Custody transfer of energy factors were analyzed, put forward some measures to reduce energy consumption. Crude oil pipeline in the transportation process, the emergence of non-normal stop the pump, close the valve by mistake, blackouts, accidents, etc. When the fire protection measures will cause water hammer phenomenon. In order to ensure the pipeline does not cause harm in accident conditions, the design of the pipeline water hammer preliminary simulations and take practical measures to protect the safety of the pipeline accident conditions and make the appropriate treatment is particularly important.In this paper, Daqing-Jinxi crude oil pipeline gap is large, diverse hydraulic conditions, etc., across the board adopted a water hammer protection control frequency regulation, pressure relief protection, stop the pump, the full range of emergency stop four protective measures to ensure pipeline accident conditions safety.
