介绍了水基植物胶压裂液所用各种交联剂的交联机理,评价了交联剂的耐温性、抗剪切性、延迟交联特性、滤失性、破胶化水性能及岩心渗透率伤害性。不同类型的交联剂适用于不同温度、不同条件的油藏。有机硼和有机硼锆交联剂在高温地层中应用性能优于硼砂和有机过渡金属交联剂。
The crosslinking mechanism of various cross-linking agents used in water-based vegetable gum fracturing fluid is introduced. The temperature resistance, shear resistance, delayed cross-linking property, filtration loss, Core permeability damage. Different types of cross-linking agent for different temperature, different conditions of the reservoir. Organic boron and organozirconium crosslinkers are superior to borax and organic transition metal crosslinkers in high temperature formations.
