| titleOfInvention | A kind of oilfield refractory scale dispersing solubilizer and preparation method thereof |
| abstract | The invention discloses a method for preparing an oilfield refractory scale dispersing solubilizer. The oilfield refractory scale dispersing solubilizer includes pyridine compounds and pyridine-N-oxide compounds, and the mass ratio is: W (pyridine compounds) : W (pyridine-N-oxide compound)=(80～85):(15～20), used in conjunction with chelating agents commonly used in oil fields, the temperature is greater than 30 ° C, can make calcium sulfate, strontium sulfate and barium sulfate, etc. Scale dissolution The scale dissolution rate is not less than 81%, which improves the scale dissolution performance. |
