Product Description

Product Description:
Calcium carbonate used in drilling is a common filler. Its main component is calcium carbonate, which is widely used in industries such as drilling, oil and gas exploration, and geological exploration. Its main function as a filler is to increase the density of the slurry, regulate the acidity and alkalinity, and prevent wellbore collapse. It can also be widely used in grouting cement, increasing pore wall stability, and improving fracturing fluid performance.
 Role and advantages:
1. Increase the density of the slurry
In deep well drilling, in order to avoid low wellbore pressure, it is necessary to adjust the density of the drilling fluid. Calcium carbonate used in drilling can help increase the density of the slurry, increase wellbore pressure, reduce the probability of downhole accidents, and improve work efficiency and safety.
2. Adjusting pH value
Adding a certain amount of calcium carbonate to the drilling fluid can adjust its pH value, make it more stable, reduce fluctuations in acidity and alkalinity, and prevent adverse effects on the wellbore and lithology.
3. Preventing wellbore collapse
Calcium carbonate used in drilling can increase wellbore support, thereby preventing problems such as wellbore collapse and ensuring work safety.
4. Application in pouring cement
Calcium carbonate used in drilling improves its flowability and delays setting time in cement-based slurry, allowing the injected cement to fully fill the pores, thereby increasing the stability of the mud column and avoiding wellbore collapse.
5. Increase the stability of pore walls
Calcium carbonate can serve as a cementitious material in rocks with relatively uniform pore distribution, thereby improving the strength and stability of the rock and avoiding wellbore and formation collapse.
6. Application in improving the performance of fracturing fluids
In the hydraulic fracturing process, adding an appropriate amount of calcium carbonate can increase the viscosity and density of the fracturing fluid, thereby improving the fracturing effect, while avoiding downhole accidents and surface equipment damage caused by excessive well fluid pressure.
