| Abstract: | The formula of O/W drilling fluid was obtained from laboratory test results which comprised 3.5 % bentonite,0.5% - 1.0% filtration reducer PAMS601A,2% - 3% temperature stabilizer agent PAMS601B, 1.5% - 2.0% main emulsifier,0.1% -0.2% auxiliary emulsifying agent B - 1, and 60% diesel fuel.The application of O/W drilling fluid at Da - 2 well was introduced. The result showed that the O/W drilling fluid system had good rheological behavior,good stability at high- temperature, good property to carry sand, good stability against pollution. The O/W drilling fluid system could adapt to under- balanced drilling technology. |
