水基植物胶压裂液用交联剂类型及性能

On crosslinking agents used for water base vegetable gum fracturing fluid

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。

Crosslinking mechanism of crosslinking a-gents used for waterbase vegetable gum fracturing flu-id are introduced. The properties of crosslinking a-gents are evaluated. It is shown that different kinds of crosslinking agents are used in reservoirs with different temperature and different condition. The properties of organic boron, organic boron zirconium crosslinking a-gents applied in reservoir with high temperature are better than that of borax and organic transitional metal crosslinking agents.
