COMPOSITE MATERIAL, COMPOSITION, DRILLING FLUID, AND METHOD FOR PLUGGING FORMATION WELL WALL FRACTURES
The present disclosure relates to the technical field of drilling, in particular to a composite material, a composition, a drilling fluid, and a method for plugging formation well wall fractures. The composite material includes a polymer matrix and metal ions embedded in the polymer matrix, an embedding rate of the metal ions is not less than 90 wt %, and turbidity of an aqueous solution of the composite material is not less than 1000 NTU under a condition of pH≤8. The composite material can actively and quickly identify a change in a formation environment based on a difference in pH values between the drilling fluid and the formation environment, and achieve a precise response and precise matching with a formation well wall fracture environment, and a small amount of composite material can effectively increase a plugging rate of the formation well wall fracture.
