Embodiment 1
[0023] Firstly, according to the SY / T 5546-2002 "Oil Well Cement Applied Performance Test Method" standard, the G-grade cementing cement slurry was prepared.
[0024] Pour the prepared G-grade cement slurry into the mold 1 with an inner diameter of 25 mm, a length of 30 mm and a length of 50 mm, seal the mold 1 and place it in a high-temperature and high-pressure curing kettle for curing for 48 hours, so that it can solidify under simulated downhole conditions to form cement stone 2 , Then take out the cement stone sample A that has not removed the mold, and use sandpaper to grind the vitrified surface. According to this method, several cement stone samples A are made according to the test requirements.
