HSTFL, a temperature-resistant, salt-tolerant and loss-of-co

I. Product Profile

This product is a temperature-resistant and salt-resistant drilling fluid filter reducer composed of sulfonated phenolic resin and sulfonated lignite. It is used together with sulfonated tannin and sulfonated asphalt. It is one of the ideal high temperature deep well mud systems.

II. Performance and Use

Temperature-resistant and salt-resistant filtrate reducer has the functions of salt-resistant, calcium-resistant and water loss reduction under high temperature and pressure. As a deep well mud treatment agent, it has good properties such as high temperature and high pressure water loss reduction, salt resistance, calcium resistance and so on. It plays an important role in consolidating borehole wall, preventing collapse and sticking. It is recommended to add 1-3%.

3. Packaging, transportation and storage

The product is packed in "three in one" bags lined with polyethylene film bags, with a net weight of 25 kg per bag, and stored in a cool, dry and ventilated place. In storage and transportation, because of its water solubility, avoid loose bags, not affected by moisture use.
