Crosslinking agent capable of crosslinking organic acid, and preparation method and application thereof

The invention relates to a crosslinking agent capable of crosslinking organic acid, and a preparation method and application thereof. The organic acid crosslinking agent is prepared from a titanium compound, isopropyl alcohol, ethylene glycol, amino acid and polyepoxysuccinic acid. The organic acid crosslinking agent is used for crosslinking of the organic acid in acidification and acid fracturingof an oil field, so the viscosity of an organic acid liquid system is increased; the temperature resistance of the acid liquid system is improved; the effective action distance of acid etching is longer; and the needs of deep-burial and high-temperature reservoirs are met. 本发明涉及一种可交联有机酸的交联剂及其制备方法与应用。所述有机酸交联剂是由钛化合物、异丙醇、乙二醇、氨基酸和聚环氧琥珀酸制成。所述的有机酸交联剂用于油田酸化酸压交联有机酸，使得有机酸液体系粘度增大，提高酸液体系的耐温性，从而酸蚀有效作用距离更长，满足埋藏深温度高储层的需要。
