Abstract: With large numbers of weight-loss experiments, the important influence of cement slurry’s stability,namely filtration and free water, on its weight-loss is found and studied. The studies shows cement slurry with better stability, namely less filtration and free water, can remain higher effective column
pressure during its setting to kick the formation fluids and prevent annular flow in waiting-on-cement.

Key words: cement slurry, weight-loss, stability, filtra-tion, free water
