كيف تُحسب

  • Annular volume = (hole area − casing area) × cemented length × (1 + excess).
  • Shoe track and rat hole are added; sacks = total slurry / yield; mix water = sacks × water per sack.
  • Displacement is the casing internal volume from surface to the float collar, so the shoe track stays cemented.
  • Class A, G, H and an extended lead slurry carry typical yields and water requirements; a laboratory blend report overrides them.

أين تتوقف عن الصحة

Volumes only. It says nothing about whether the cement will do its job: mud removal depends on centralisation, standoff, pipe movement and a spacer that actually displaces in turbulence, and a job with correct volumes and 40 % standoff still leaves a channel. Yields shift with additives and with mix-water salinity, so a job designed on these numbers must be re-checked against the blend report.
