Study on Treatment of Abandoned Drilling Fluid

Abstract

The requirements of environmental protection are more stringent in recently years, the treatment of abandoned drilling fluid generated during the drilling process has also become an urgent problem to be solved. In view of the development status of domestic abandoned drilling fluid disposal methods, discussing the disposal methods of water-based and oil-based abandoned drilling fluids from both offshore and onshore abandoned drilling fluids in this paper. The comparative analysis of treatments of abandoned drilling fluids at offshore and onshore are carried out, and the more suitable treatments of abandoned drilling fluids are selected, which play a guiding role in field operation.
