摘要
地处沙漠腹地的西部某油田,集输系统采用一级半布站方式。集输管线经过长时间的运行和单井含水的升高,腐蚀穿孔现象发生频繁。为缓解严峻的形势,于2012年9月至2013年1月完成管线更换工作,时间正值冬季,为了能够不停产对1#、2#生产汇管进行更换后投产,采用站外注水系统对旧管线进行注水替油、增加地温、流程互相切换的方式进行不停产投产,取得一次性成功,为沙漠地区冬季集输管道投产运行积累了宝贵经验。
Certain oilfield located in desert hinterland of the western China was developed in 1996 and one and a half station layout type was applied in its gathering and transportation system. Due to long time operation and continuous single well water content increase,corrosion perforation occurs frequently in its gathering and transportation system. In order to alleviate the severe situation,the pipeline was updated during the winter time from 2012 September to 2013 January. The offsite water injection system was used for water injection and oil replacement of the oil pipeline,ground temperature increase and flow switch to each other so as to replace 1# and 2# production manifolds in the gathering and transportation pipeline system without shutdown and one-time success was achieved,from which valuable experience has be accumulated for putting gathering and transportation pipelines into production without shutdown in desert area winter.
