在老油田的开发过程中，油田集输管线受输液介质的腐蚀和磨损，有效使用寿命越来越短。对油田集输管线使用状况的正确认识及对造成集输管线失效内在原因的分析和研究，是制定油田集输管网更新改造计划的基本依据。对胜坨油田１５９ｍｍ以上的１９９条集输管线运行状况进行调查分析表明，集输管线寿命与输液介质流速有关。管线内腐蚀是造成管线失效的主要原因；钢质管线材质不适应目前的管线输液介质环境是造成管线失效的内在原因；管网结构不适应流量增长的需要是造成管线失效的最根本原因。胜坨油田的管网改造要改变管线更新改造的设计思路，调整管网结构，并结合胜坨油田的输液介质环境，试用不同材质的管线。
During the development of the old oilfields, the gathering and transportation pipelines of the oilfield are corroded and worn by the infusion medium, and the effective service life is shortened. Correct understanding of the utilization status of the gathering and transportation pipelines in the oilfield and the analysis and research on the internal causes of the failure of the gathering and transportation pipelines are the basic basis for formulating the plan of upgrading and reorganizing the oil gathering pipe network. Investigation and analysis of operating conditions of 199 gathering and conveying pipelines above 159mm in Shengtuo Oilfield shows that the life of the gathering and conveying pipeline is related to the flow rate of the infusion medium. Pipeline corrosion is the main cause of pipeline failure; steel pipe material does not adapt to the current pipeline infusion medium environment is the inner cause of pipeline failure; pipe network structure does not meet the needs of traffic growth is the most fundamental cause of pipeline failure. Shengtuo Oilfield pipe network transformation to change the design of pipeline renovation, to adjust the pipe network structure, combined with Shengtuo oil field infusion medium environment, try different materials pipeline.
