Phenolic resin with higher consolidation strength at low temperature (30～ 40 ℃) was synthesized by optimizing structure of phenolic resin according to its sand-control mechanism.

根据酚醛树脂的防砂机理,设计合成出在低温(30~40℃)下具有较高固结强度的酚醛树脂,达到同样固结强度的其用量降低,因而降低了油井施工成本。

The result showed that the sand - consolidating agent had higher consolidating strength and permeability and very good acid resistance , salt resistance, oil resistance, and heat resistance.

结果表明,研制的固砂剂具有较高的固结强度和渗透性及优异的耐酸、耐盐、耐油和耐温性能。
