摘要（英）：

The invention discloses a displacement sensing system for measuring expansion and shrinkage amounts of a high-temperature high-pressure solidified body after solidification. The system comprises a kettle body provided with a temperature and pressure control system, a mold arranged in the kettle body and internally provided with a cavity filled with a to-be-solidified body, a probe assembly which penetrates through the mold and is fixedly connected to a measuring point part of the to-be-solidified body, a displacement sensing device which comprises a tube body, a slide rod arranged in the tubebody and capable of sliding in the tube body and an induction element arranged on the outer side of the tube body and used for detecting a displacement of the slide rod, and a connecting piece used for enabling the probe assembly to be in hard connection with the slide rod of the displacement sensing device. The displacement sensing system can be used for measuring radial micro expansion and shrinkage amounts of a well cementation cement ring.
