Abstract | The invention discloses a preparation method of a composite plugging agent based on pulping pre-hydrolysate, and relates to a composite plugging agent, the pulping pre-hydrolysate is used as an enhancer, under the action of a cross-linking agent, the pulping pre-hydrolysate and a high-molecular polymer form multiple cross-linked jelly at a certain temperature, and the composite plugging agent is prepared. The obtained multi-crosslinking gel system has good temperature resistance, salt resistance and strength stability. The product prepared by the invention has the characteristics of simplicity in use, environment friendliness, adjustable freezing time and strength of the formed jelly, good temperature resistance and the like.
本发明公布了一种基于制浆预水解液的复合堵漏剂的制备方法,涉及复合堵漏剂,使用制浆预水解液作为强化剂,在交联剂的作用下,制浆预水解液与高分子聚合物在一定温度下形成多重交联冻胶体,所得的多重交联冻胶体系具有较好的耐温、耐盐以及强度稳定性。本发明所制备的产品具有使用简单、绿色环保、形成的冻胶成冻时间和强度可调、耐温性好等特点。 |
