Abstract

Disclosed is an experimental device for the real-time monitoring of the sealing integrity of a cement sheath for well cementation, the device comprising a fixing device (1), a well bore device (2) and a cement slurry injection system (3), wherein the bottom end of an inner casing (22) and the bottom end of an outer barrel (21) are both fixed within a base (12); a cavity between an inner wall of the outer barrel (21) and an outer wall of the inner casing (22) forms a cement sheath cavity (24); an optical fiber sensing cable (23) is arranged on the outer wall of the inner casing (22); a cement slurry storage device (31) is in communication with the cement sheath cavity (24) via a cement slurry injection pipe (32); and a cement slurry injection pump (33) is provided on the cement slurry injection pipe (32). The experimental device for the real-time monitoring of the sealing integrity of a cement sheath for well cementation achieves the real-time continuous monitoring, in a whole well section, of the sealing integrity of a cement sheath for well cementation, with precise and reliable measured values. For different experiments for monitoring of the sealing integrity of a cement sheath, it is only necessary to replace same with outer barrels having different functions for simulating strata and pipelines, and corresponding injection systems, which greatly reduces the experiment cost.
