摘　　要：HCO3-、Ca2+、Mg2+是油田采出水中成垢的主要离子,通过考察水中HCO3-、Ca2+、Mg2+与水中悬浮物含量变化的关系来研究HCO3-、Ca2+、Mg2+三种离子的成垢规律及结垢对水中悬浮物的影响。结果表明HCO3-和Ca2+、Mg2+反应生成Ca CO3和Mg CO3是成垢的主要原因,其中起主要作用的是Ca2+;水质改性技术可以降低采出水中的HCO3-或Ca2+、Mg2+含量,达到防腐、阻垢、净化水质的效果。Bicarbonate ion, calcium ion and magnesium ion are primary ions for scale formation. In this paper, the relationship between content change of bicarbonate ion, calcium ios, magnesium ion and suspended substance was investigated to study the scale formation regulation of these ions and the influence of scale formation on suspended substance. The results show that calcium carbonate and magnesium carbonate generated by reaction between calcium ion, magnesium ion and bicarbonate ions are the main reason of scale formation, and the calcium ions play a major role The content of bicarbonate ion, calcium ion and magnesium ion can be reduced by water quality modification technology, which can play the role of corrosion prevention, scale prevention and water purification.
