9 5/8" casing cement

We drilled 12 1/4" to TD @ 2995m in cap rock and ran casing to 2994m and cemented same in place.After cement job and before cement get hard, observed pressure in annulus up to 1700psi. what can be the reason? We think that cement is not uniform dowhnole, Also what happened to water in hole after cement is set, since sometimes we see water in cement samples.

Thanks alot
Amir
