Dear Experts
my plant plan to start producing oil well cement
I know that oil well cement need additional special tests
So,
1- I would like to know what are the exactly required tests for this type of cement ( physical tests , chemical tests and Mechanical tests )
2- what are the equipment needed for these special types of tests for oil well cement
Best regards
Dear Electron1539,
Oilwell cement is required to meet the API Specifications 10-A which requires following tests;
Chemical analysis to determine:
MgO, SO3, Loss On Ignition, Insoluble Residue, Total alkalies as Na2O, C3S and C3A
Physical Tests:
Mix Water as % mass fraction of cement
Fineness either by Turbidimeter or Air Permeability
Free Fluid Content
Compressive strength at specified temperatures and pressures
Consistency
Pressure Temperature Thickening Time Test
Equipment required:
Electronic balance
Apparatus to determine fineness (Blaine or Turbidimeter)
Oven
Water bath
Water bath with agitator
Compressive strength testing machine with accessories
Atmospheric consistometer
Pressurized consistometer
Constant speed mixer
Best regards,
S.M. Imran
