2. Product Property
Non qualitative white powder. Non toxic, not soluble in water,
soluble in smoking Sulphuric Acid, slightly soluble in boiling
Hydrochloric Acid. Chemical property is stable, it’ll reduce to
Barium Sulfide when heat with carbon. It wont change color when
meeting with hydrogen sulfide or toxic gas in the air.
3. product usage
Applicated to oilfields,construction and chemical industried.Barite
powder can add weight to well-drilled mud as a weighting agent for
all types of drilling fluids.
4. Liangjiang brand ultrafine barium sulfate production process
5. The drilling mud weighting agent to the requirement of barium
sulfate:
some oil and gas well drilling, the general use of drilling mud,
clay proportion of 2.5 or so, the proportion of water is 1, so the
mud weight is low, sometimes the mud weight can't with underground
oil and gas pressure balance, has caused the blowout accident.Under
the condition of the underground pressure is higher, you need to
increase the mud weight, supplying the mud with barium sulfate is
an effective measure to increase the mud weight.Do drilling mud
with barium sulfate general fineness to achieve more than 325 mesh,
such as barium sulfate fineness is not prone to
precipitation.Drilling mud with barite for weighting is greater
than 4.2, BaSO4 content not less than 95%, less than 1% soluble
salts.
Because professional, so we do better!
we aspires to be the world's leading chemical raw materials supply
service, the value of that made in China should have!
