Barium carbonate nanoparticle powder is produced by liquid-liquid phase reactive precipitation in a Rotating Packed Bed (RPB) from industrial refined barium chloride and ammonium bicarbonate.
以工业精制氯化钡和碳酸氢铵为原料，在旋转填充床中采用液—液相反应沉淀法合成碳酸钡纳米粉体。

In the injection process, the barium ion and sulfate ion chemical reactions occur in the reservoir, but the barium sulfate precipitation mainly concentrated in the near wellbore.
在注水过程中，钡离子和硫酸根离子的化学反应虽然发生在整个储层中，但是硫酸钡沉淀主要集中在近井带。
