| Abstract: | In this Paper, the effects of the changes of temperature and pressure
on the formation stress around bottom hole during waterflooding are disc
ssed, and the change values in formation stress are determined depending
on the basic theory of thermoelstic dynamics and filtration mechanics It
is important to determine injecton pressure and study casing damage and
reservoir burst pressure. |
