摘要
介绍了新型低损害合成聚合物压裂液体系,该压裂液体系采用的稠化剂FA-200A为几乎不含水不溶物的合成聚合物,体系的残渣少;使用交联剂AC-12A进行交联,交联时的pH值为5~6,形成的冻胶具有良好的耐温耐剪切性能,不需要其它的pH值调节剂,既适合于常规压裂,又适合于液氮助排。新型低损害合成聚合物压裂液适用温度大于50~90℃,与植物胶压裂液相比,新型低损害合成聚合物压裂液不使用杀菌剂。该压裂液的成本低于清洁压裂液。
A new type of synthetic polymer fracturing fluid with low formation damage is introduced in this paper. The gellant FA-200A used in this new fracturing fluid system is almost free of insoluble materials. The pH value of the crosslink is 5-6 using AC-12A as the cross linking agent. This new fracturing fluid system is suitable for use in both conventional hydraulic fracturing and liquid N_2 foamed fracturing. Application temperatures of this new fracturing fluid system are 50-90 ℃. Comparing with guar fractur...
