| Abstract: | This paper introduces the results of study and application in block wide watershutoff southwest chengdong oilfield, including the evaluation and improvement of chromium gel used in single fluid method, screening of the precipitatedtype plugging agent used in double fluid method, changing the chromium gel into a plugging agent which can be used in double fluid method, introducing the chrconium gel and using leak plugging agent etc. According to the programme of watershutoff,11267m3 of above-mentione different plugging agents have been put into formation.During the test period, the annual increasing of water cut has been controlled to a level of less than 2% and increased of oil production has reached 3×l04t. |
