ActiveDetermination of shrinkage and expansion of well cement formulations at atmospheric pressure
常压下油井水泥收缩与膨胀的测定
Application Summary AI generated
This standard specifies a test method for measuring the linear shrinkage and expansion of well cement slurries cured under atmospheric pressure conditions. It is applied in the petroleum industry for evaluating the dimensional stability of cement formulations used in oil and gas well construction, particularly to assess the risk of cement sheath integrity loss due to volume changes. The test is critical for quality control and formulation optimization in well cementing operations.
