在油田开发中 ,由于油井结蜡、地层出砂、油藏高含水等原因使油井时常需要进行刮蜡、冲砂、验窜 ,而目前生产中应用的常规方法是将刮蜡、冲砂、验窜分开进行 ,为了提高工作效率 ,降低生产成本 ,研制了一种新型的井下工艺管柱———组合式多功能井下工艺管柱。该管柱能将常规方法中分开进行的刮蜡、冲砂、验窜三项施工工序合为一项 ,提高工效 2倍 ,既节约费用 ,又能保证施工质量 ,同时还提高了油水井的工作时数
In the field of oilfield development, due to waxing in oil wells, sand formation, and high water cut in oil reservoirs, oil wells often need to undergo scraping wax, sand blasting and channeling tests. However, conventional methods used in production at present are: scraping wax, In order to improve the working efficiency and reduce the production cost, a new type of downhole process string-the modular multi-purpose downhole process string has been developed. The column can be separated from the conventional method of scraping wax, red sand, inspection channeling three construction processes into one, to improve work efficiency 2 times, both to save costs, but also to ensure the construction quality, but also to improve the oil and water wells Working hours
