湍流-切割管道时留下的毛刺使流体产生旋转作用，导致局部侵蚀，从而最终造成故障。
Turbulence - burrs left on the cut tubing causes a tumbling effect causing localized erosion and eventual failure.
另一方面使水泥浆具有防窜性，减轻了地层流体对水泥环的侵蚀。
It can reduce cement slurry filtration, provide a channeling-preventing effect and mitigate corrosion of formation fluids on cement ring.
