barite for oil drilling (325mesh) faq
increase the drilling mud agent: in some wells, gas well drilling, the general use of the drilling mud, clay, accounting for around 25, the proportion of water to 1, so the lower the proportion of mud, sometimes mud weight can not be underground oil and gas pressure balance, causing blowout. in the ground under high pressure, the need to increase the proportion of mud, barite powder added to the slurry is an effective measure to increase the proportion of mud. barite used in drilling mud to do the general fineness of 325 or more to achieve, such as the fineness of barite precipitation is easy enough. requirements with the barite drilling mud weight is greater than 4.2, baso4 content of not less than 95%, less than 1% of soluble salts.
use:
1. as a weighting agent for drilling fluids in oil and gas exploration.
2. used in the car, electronics, tv screen, rubber, and glass ceramics and paint industry.
3. as surface smear for photographic paper and calendered paper; as sizing agent for textile industry.
4. as clarifying agent for glass products.
5. radiation shielding and medical applications; also used for ceramics, enamel, perfumes and pigments.
