High-temperature-resistant precoated sand for sand prevention of oil well and preparation method thereof
The invention discloses high-temperature-resistant precoated sand for sand prevention of an oil well and a preparation method of the high-temperature-resistant precoated sand. The preparation method comprises the following steps: reacting rosin with epoxidized soybean oil to obtain rosin modified epoxy resin; thermoplastic phenolic resin and rosin modified epoxy resin react to obtain epoxy modified phenolic resin; the epoxy modified phenolic resin is dissolved in a solvent, an organosilane coupling agent is added for a reaction, and organosilicone modified epoxy phenolic resin is obtained; and heating and mixing the organic silicon modified epoxy phenolic resin, quartz sand and a curing agent to obtain the high-temperature-resistant precoated sand for sand prevention of the oil well. The high-temperature-resistant precoated sand for sand prevention of the oil well, which is disclosed by the invention, has relatively high temperature resistance and medium resistance.
本发明公开了一种油井防砂用耐高温覆膜砂及其制备方法，通过将松香和环氧大豆油反应得到松香改性环氧树脂；热塑性酚醛树脂、松香改性环氧树脂反应得到环氧改性酚醛树脂；将环氧改性酚醛树脂溶于溶剂中，加入有机硅烷偶联剂反应，得到有机硅改性环氧酚醛树脂；将有机硅改性环氧酚醛树脂、石英砂、固化剂加热混合，得到油井防砂用耐高温覆膜砂。本发明得到油井防砂用耐高温覆膜砂，具有较强的耐温性及耐介质性。
