井下柔性復合管注水技術(shù)及應用
[Abstract]:At present, the corrosion and scaling of produced water in Changqing Oilfield is serious, which results in the short service life of steel anticorrosive tubing. Through mechanical calculation and structural material optimization, a flexible composite pipe with different diameters is developed, and the strength check, finite element analysis and indoor performance evaluation of the pipe string are carried out. A series of downhole flexible composite pipe injection technology string is formed, which is suitable for producing water injection well. There are 32 wells tested in the field, the test success rate is 100 and the longest injection time of the test well has reached 4 years up to May 2016. The sampling performance test of 12 wells shows that the downhole flexible composite pipe has good anticorrosion performance and can effectively improve the service life of water injection pipe string. The estimated service life is more than 10 years, which is more than twice the service life of steel anticorrosive oil pipe. At the same time, the process can effectively reduce the working intensity and production cost, and has a broad prospect of popularization and application.
