| Abstract: | A Novel anti- sloughing drilling fluid is selected to deal with instability hole in Shangtaizi area,Liaohe basin. Anti- sloughing property is evaluated through soaking cutting, recovery rate of shale and swelling rate shale in laboratory. Tests on two wells indicated that DZ-31 drilling fluid system possesses advantage of stabilization, good cutting transportation and inhibition, resisting high temperature. This kind of drilling fluid is suitable for protecting oil and gas formation without environment pollution. It is beneficial for adjustment of fluid performance and less cost in deep well. |
