Harm of CaCO3 and CaSO4 in Oilfields:

In oilfields, CaCO3 (calcium carbonate) and CaSO4 (calcium sulfate) are common deposits that can have adverse effects on oilfield operations. These hardness scales can deposit and accumulate inside pipelines, equipment, and wellbores, causing a reduction in pipeline diameter, equipment blockages, and ultimately affecting the production efficiency of the oilfield. Scale deposition can also lead to a decline in oil well productivity, reducing permeability and resulting in decreased oil output. Furthermore, the presence of scales can provide a favorable environment for corrosion, increasing corrosion rates and potentially damaging equipment, thus reducing its service life.

To address the harm caused by CaCO3 and CaSO4, oilfields often use scale inhibitors for water injection, such as those composed primarily of organic phosphonates and imidazolines. These inhibitors demonstrate excellent scale inhibition performance, especially in high-temperature and high-pH conditions, with a particular focus on inhibiting CaCO3 and CaSO4. They have the advantage of requiring minimal dosage on-site, good water solubility, and compatibility with other oilfield chemicals. By using these scale inhibitors, the formation of hardness scales can be effectively prevented, ensuring normal operation and production capacity of the oilfield equipment, while also extending the equipment’s service life.

Our scale inhibitor for water injection (CaCO3, CaSO4 Type) is the ideal choice for addressing scale-related issues in your oilfield. It is formulated primarily with organic phosphonates and designed to perform exceptionally well in high-temperature and high-pH conditions, particularly for inhibiting CaCO3 and CaSO4. By minimizing the formation of hardness scales, it effectively prevents pipeline diameter reduction and equipment blockages, thereby improving oilfield production efficiency and ensuring that oil well productivity remains unaffected.

Additionally, our product requires minimal dosage, possesses good water solubility, and exhibits excellent compatibility with other oilfield chemicals, providing convenience for on-site production. The appearance of the product is a uniform liquid, with a pH range of 4.0 to 8.0, and a density ranging from 0.95 to 1.10 g/cm³. The scale inhibition rates for CaCO3 and CaSO4 are both above 93.0%, ensuring outstanding performance.

Our scale inhibitor has a wide application range and is especially suitable for preventing scale formation in oilfield water injection pipelines. Simply follow standard procedures and adjust the dosage based on on-site production requirements.

The product is packaged in plastic drums, with options of either 25kg or 200kg net weight, providing ease of storage and use. To ensure product quality, please store it in a cool, dry, and well-ventilated area, with a shelf life of one year.

We believe that our scale inhibitor will provide powerful scale inhibition effects, prolong equipment lifespan, and help optimize your oilfield operations. Throughout the production process, our laboratory team remains vigilant in closely monitoring your oilfield’s geological conditions, continuously adjusting and preparing suitable scale inhibitors to meet your specific needs.

We are confident that our scale inhibitor will deliver exceptional performance in different oilfield conditions, adding significant value to your oilfield operations. Should you have any further questions or requirements, please feel free to contact us.
