| Abstract: | This paper presenst the fundamentals of plugging and sealing off channeling of production wells and laboratary experiment, field test and their results. The result of the field test shows that the plugging and sealing off channeling technology is stronger with greater success and in combination with antipollution string, it can effectively prevent non-chemical plugging pay zone from damaging. Plugging and sealing off channeling can be completed simultaneously and comparing with stronger chemical plugging, each well can save the cost of plugging agent about 12 thousands yuan. |
