DRILLING FLUID AND COMPLETION FLUID TECHNOLOGY FOR RESERVOIR PROTECTION IN JINGDONG OILFIELD

    Graphical Abstract
    • Abstract
  • The geological characteristic of Chang-2 reservoir in Jingdong Oilfield of Shanganning Basin is described, and the specific type of formation sensitivity and degree of formation damage are also investigated. A highly inhibitive MMH drill-in fluid system is designed based on the study of formation damage mechanism. At the same time, dynamic formation damage evaluation is carried out. Field testing in six wells shows its effective formation protection capability.
