NOVELTY - A well wall reinforcing composition comprises 100 pts. wt. cement, 5-30 pts. wt. cementing agent, 5-20 pts. wt. interface strengthening agent, 1-5 pts. wt. active filling agent, 0-40 pts. wt. high temperature stabilizer, and 35-60 pts. wt. water, where the cementing agent comprises epoxy resin and epoxy resin emulsifier, plasticizer, and nanomaterials. USE - Well wall reinforcing composition for crushing stratum (claimed). ADVANTAGE - The well wall reinforcing composition overcomes the disadvantages of bad adhesive performance of existing cement and carbonate rock, hard after curing, brittle, not impact resistance, and cannot be used for crushing stratum well wall reinforcement. The well wall reinforcing composition has high bonding strength with limestone, carbonate and other rocks after solidification, and excellent elasticity, does not cause the problem of breakage and loss of blocks after the drill pipe collides, and can be used to solve the instability problem of wellbore wall of deep well fractured formation. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1.the preparation method of the well wall reinforcing composition for crushing stratum, which involves mixing cement, cementing agent, interface strengthening agent, active filling agent, high temperature stabilizer, and water according to the dosage to obtain a final product; and 2.an application of the well wall reinforcing composition in crushing stratum treatment.
