一种改性树脂固砂剂及其制备方法与应用
摘要：
本发明涉及一种改性树脂固砂剂及其制备方法与应用。所述固沙剂主要成分为：环氧树脂为主剂，固化剂用量为6.0％～7.0％；软化剂用量为15％；稀释剂用量为20～22％；偶联剂用量为2％；玻璃纤维用量为10％；除环氧树脂以外的其他成分的百分比用量是以环氧树脂为100％计，所述百分比为重量百分比。其制备包括：所述的改性树脂固砂剂用于油井出砂的防治。所述使用方法包括：使用前置清洗液预处理地层，然后从油管注入固砂剂，最后使用顶替扩孔液将固砂剂顶替到地层深处。本发明形成的固砂剂配方，能够解决油井出砂影响生产的难题，适合不同出砂粒径。
摘要（英）：

The invention relates to a modified resin sand consolidation agent as well as a preparation method and an application of the modified resin sand consolidation agent. The sand consolidation agent mainly consists of epoxy resin as a main agent, 6.0-7.0% of a curing agent, 15% of a softener, 20-22% of a diluent, 2% of a coupling agent and 10% of glass fiber; and the dosages of the other components expect the epoxy resin is weighed by 100% of the epoxy resin in percentage by weight. The preparation comprises that the modified resin sand consolidation agent is used for preventing and curing sand production in oil wells. The application method comprises the steps of: pre-treating the stratum by using pre-cleaning fluid, then pouring the sand consolidation agent from an oil tube, and finally replacing the sand consolidation agent to the deep of the stratum by using replacement pore-broadening liquid. The formula of the sand consolidation agent disclosed by the invention can solve the problem of influence of sand production in oil wells on the production and is suitable for different sand grains.
