Abstract

See full text

The invention discloses a device for testing strength and sealing performance of cement sheath after perforation, comprising a cement sheath curing maintenance simulation component, a perforation operation simulation component, and a cement sheath performance test component. By simulating the detonation effect and fluid-solid coupling effect, quantitatively testing the internal transverse crack and longitudinal crack propagation size, compressive strength and tensile strength, permeability, blowby pressure, blowby velocity and other parameters of the cement sheath, drawing the relation curve between different perforation distances and the maximum blowby pressure and permeability of the cement sheath, determining the perforation distance Hp where the blowby of the cement sheath does not occur, determining the perforation distance HK to ensure the sealing of the cement sheath, and using min (Hp, HK), the critical perforation distance that the cement sheath has sufficient strength to prevent blowby and meet the sealing requirements can be determined.
