摘要
评价了有机硼交联的羟丙基瓜尔胶压裂液体系的延迟交联特性、耐温性、耐剪切性、流变性、粘弹性、破胶特性、滤失性能、残渣含量及对地层的伤害。该压裂液体系具有可控制的延迟交联作用、良好的耐高温和剪切恢复特性、快速破胶、助排能力和携砂能力强、储层伤害小等特点,可满足低、中、高温油气藏压裂的需要,能取得良好的施工和增产效果。
A fracturing fluid system composed of organo-borate crosslinking agent and hydroxypropyl guar is investigated. Tests indicate that this fracturing fluid system possesses the advantage of delayed crosslinking, good thermal stability, quick breaking property and good proppant carrying capacity. Applications of 52 wells indicate that this fracturing fluid system can satisfy the demand of fracturing operation in reservoirs with different temperature.
