复合多价金属离子交联剂及其生产方法和使用方法
摘要：
本发明涉及用于石油开采的调堵剂及其交联剂的技术领域，是一种复合多价金属离子交联剂和高强度调堵剂及其生产方法和使用方法；该交联剂组成为柠檬酸铬、乳酸锆、柠檬酸铝、有机硼、有机钛、双酚A、间苯二酚、乌洛托品和余量的水。本发明的特点：所得到的复合多价金属离子交联剂和高强度调堵剂的成本都较低，配制方法简单且效率高。该复合多价金属离子交联剂与聚合物形成的高强度调堵剂，适用于高含水油层堵水，还具有较强的适应性，不但能利用工业水还能利用油田污水进行回注油层调堵水，有效地提高调堵剂的强度及耐温性，其耐压为3MPa至15MPa、耐温为30℃至150℃。
摘要（英）：

The invention relates to the technical field of profile-modifying and plugging agents for oil extraction and crosslinking agents thereof, in particular to a compound multivalent metallic ion crosslinking agent, a high-strength profile-modifying and plugging agent, and a production method and a use method thereof. The crosslinking agent comprises chromium citrate, zirconium lactate, aluminum citrate, organic boron, organic titanium, bisphenol A, resorcinol, methenamine and the balance of water. The invention is characterized in that the compound multivalent metallic ion crosslinking agent and the high-strength profile-modifying and plugging agent have the advantages of low cost, simple preparation method and high efficiency. The high-strength profile-modifying and plugging agent formed by the compound multivalent metallic ion crosslinking agent and polymers is suitable for plugging water for high water-cut oil layers and has strong adaptability. The high-strength profile-modifying and plugging agent can plug water in the recycle oil layer by utilizing industrial water and oil field sewage so as to effectively enhance the strength and the temperature resistance of the profile-modifying and plugging agent. The profile-modifying and plugging agent can resist a pressure of 3-15 MPa and resist a temperature of 30-150 DEG C.
