摘　　要：由于大港油田板879-4区块地层敏感性较强,设计钻井液时要特别考虑其抑制性和钻井液的pH值。在室内研究了一套JHM无粘土钻井液体系,该钻井液体系具有保护储层及环境、抑制性强等特点,特别适合于储层敏感性较强的地区。In view of the formation sensitivity of Ban 879-4 Block of Dagang Oilfield is strong, the rejection capability and pH value of the drilling fluid should be taken into account when it is designed. A novel JHM clay free drilling fluid system has been studied in laboratory. The system can defend reservoir and environment with strong rejection capability, and it is fit for drilling strong formation sensitivity reservoir especially.
