Special scale inhibitor for oilfield reinjection water

1. Function and use

The scale inhibitor is composed of a variety of organic phosphonic acids, special surfactants, synergists, etc., which can chelate Ca2+ and Mg2+ in water and inhibit the formation of scale through lattice distortion. It has good chelating and dispersing effect on calcium carbonate, calcium sulfate and calcium phosphate in water. The scale inhibitor has the characteristics of high temperature resistance, alkali resistance, salt resistance, stability under oil reservoir conditions and low dosage.

3. Application scope and use method

This product is mainly used for scale inhibition and descaling of strata and pipelines in the process of oil production to prevent the blockage of strata and pipelines caused by scale formation. Add the daily scale inhibitor into the plastic dosing bucket (or box), and add the agent continuously with the metering pump or through the regulating valve after diluting with water for convenience. According to the amount of water injected, the amount of scale inhibitor is generally 10~50mg/L, and the specific amount should be determined according to the water quality.

4. packaging and storage

Plastic drum packaging, 25kg/ drum, 200kg/ drum or according to user needs to determine; Store in a cool and dry place for 10 months.

5. Safety and protection

Type I and type II scale inhibitors for oilfield reinjection water are acidic and alkaline. Avoid contact with eyes, skin or clothing, and rinse with plenty of water immediately after contact (at least 15 minutes).
