What kinds of equipment are needed in an oil - gas cementing laboratory? Here are some examples.
The laboratories of cement plants can also refer to these.
Cement slurry preparation instruments
- Laboratory concrete mixer: used to mix cement, water and admixtures to prepare uniform cement slurry.
Cement slurry curing instruments
- Cement curing box: can accurately control temperature and humidity to provide a suitable curing environment for cement slurry.
- Cement curing water tank: used to immerse cement slurry specimens in water for curing and maintain constant humidity.
Thickening test instruments
- High temperature and high pressure consistency meter (HPHT Consistometer): simulates the high temperature and high pressure environment of oil wells to test the thickening process and time of cement slurry.
- Normal pressure consistency meter: measures the change of cement slurry consistency over time under normal pressure.
Gas channeling / static gelling test instruments
- Gas channeling tester: simulates the downhole environment to detect the ability of cement slurry to prevent gas channeling during the solidification process.
- Static gelling strength tester: measures the development of static gelling strength of cement slurry in the initial setting stage.
Water loss test instrument
- High temperature and high pressure water loss instrument: Determine the water loss of cement slurry under simulated high temperature and high pressure conditions in the well.
- Normal pressure water loss instrument: Used to test the water loss of cement slurry under normal pressure environment.
Rheological test instrument
- Rotational viscometer: Measure the viscosity of cement slurry at different shear rates and evaluate its rheological properties.
- Rheometer: Comprehensively analyze the rheological properties of cement slurry, such as plasticity, pseudoplasticity, etc.
Compressive strength test instrument
- Pressure testing machine: Apply pressure to the cured cement slurry specimen to determine its compressive strength.
- Digital display compressive strength tester: Accurately display the pressure value, which is convenient for accurately obtaining the compressive strength data of cement slurry.
