阅读说明：本技术 一种裂缝暂堵转向剂及其在暂堵转向加砂压裂工艺中的应用 (Temporary fracture plugging diverter and application thereof in temporary plugging diverting sand fracturing process ) 是由 张锋三 郭庆 吴金桥 韩伟 白方林 孙晓 穆景福 张军涛 王振川 许亮 王卫刚 于 2021-08-31 设计创作，主要内容包括：本发明公开一种裂缝暂堵转向剂,由以下原料组成：聚丙烯酸钠、聚乙烯醇、聚碳酸酯、KCl、过硫酸铵,聚丙烯酰胺,水；针对致密储层中岩心脆性矿物含量不同,所述裂缝暂堵转向剂包括三种,分别为裂缝暂堵转向剂A、裂缝暂堵转向剂B、裂缝暂堵转向剂C。同时,本发明还公开所述裂缝暂堵转向剂在暂堵转向加砂压裂工艺中的应用。所述裂缝暂堵转向剂采用水溶性较好的聚合物材料,设计出“瞬间桥堵”的封堵方式,通过三种不同粒径聚合物的相互组合,快速形成可耐压封堵墙,实现其他甜点区裂缝的开启,进一步增大了裂缝改造体积,与常规暂堵方式相比,具有“堵得快、稳得住、易溶解”的特点。(The invention discloses a crack temporary plugging diverting agent, which consists of the following raw materials: sodium polyacrylate, polyvinyl alcohol, polycarbonate, KCl, ammonium persulfate, polyacrylamide and water; aiming at different rock core brittle mineral contents in compact reservoirs, the fracture temporary plugging diversion agent comprises three diversion agents, namely a fracture temporary plugging diversion agent A, a fracture temporary plugging diversion agent B and a fracture temporary plugging diversion agent C. Meanwhile, the invention also discloses application of the temporary plugging diversion agent for the cracks in a temporary plugging diversion sand adding fracturing process. The temporary crack plugging diverter is made of polymer materials with good water solubility, an instant bridging plugging mode is designed, a pressure-resistant plugging wall is quickly formed by mutually combining three polymers with different particle sizes, cracks in other dessert regions can be opened, the crack modification volume is further increased, and compared with a conventional temporary plugging mode, the temporary crack plugging diverter has the characteristics of being fast in plugging, stable in plugging and easy to dissolve.)
