    Abstract
  • Osmotic hydration of shale is one of the important factors for borehole wall instability. Based on the activity equilibrium theory of drilling, a new idea of “moderate reduction of the activity of drilling fluid” has been presented. In this paper, the theoretical basis of this idea is analyzed. The idea was verified in laboratory through hydration and disintegration experiments, and as a result of the research work, a new method of determining the activity of the drilling fluids was established. It was found in the laboratory experiment that a cylindrical core can still retain its stability when the activity of the drilling fluid is moderately higher than the activity of the water in the core. The “moderate reduction of the activity of the drilling fluid” technology has been applied in the drilling operation in several blocks in Jiyang Depression, and it was found that “moderate reduction of activity” can be used to solve the borehole wall destabilization problem which is a result of collapse and caving of shale formations in these blocks. The wells were successfully drilled and completed, and downhole troubles were avoided, greatly saving the drilling time and drilling cost.
