This standard specifies the test methods and determination rules for the compressive strength and permeability of oil well cement stone after high-temperature curing. This standard is applicable to the evaluation of the high-temperature resistance of oil well cement stones after cement injection operations in thermal recovery wells and high-temperature wells (the static temperature at the bottom of the well is greater than or equal to 150°C). The evaluation of the high temperature resistance performance of oil well cement admixtures can be used as a reference.
