CEMENTING SYSTEMS FOR OIL WELLS

摘要

A process for determining suitable parameters of temperature and/or pressure to use in a cementing operation in a wellbore to obtain a positive sealof cement in an annulus between a liner and a borehole wall after the cement has set up and where the process utilizes the parameters of differential temperature in a well bore, pressure on the cement to obtain a positive boreholewall stress (and positive seal) in a cementing operation.
