| Abstract: | Precise water detection and blocking technique has been studied for the problem of high water cut in oil wells of Liaohe oilfield. This water blockoff string includes DY445 packer, Y341 self- checking packer, Y211 packer, KG universal switch and safety joint. The string is suitable to 178 and 124 mm casing. Field application in 15 wells shows that average daily oil increment of single well is 5t, and the effectiveness of water detection and blocking has been remarkably improved. |
