%X Well cementing is an important operation in the construction of any oil well.After a section of the steel casing is inserted into the hole,a sequence of cement slurry is pumped down the inside of the tubing and coming back up through the annular gap,and then allowed to settle in the annulus.Several fluid mechanics problems are discussed in the present paper,such as,how to determine the mechanical models for describing rheological behavior of cementing slurry at high temperature and high pressure,the influences of eccentricities on slurry flow,and the stability of the interface between slurry and spacer.This paper briefly reviews the latest investigations on fluid mechanics problems,and some important directions for future researches are pointed out.
