浅议新型低伤害增能压裂液体系

On the New Type Low-damage and Energy Increasing Fracturing Fluids System

针对新疆油田低压、低渗、水敏油气藏压裂改造中常规压裂液体系存在的对储层伤害大等问题,研制了一种新型压裂液——新型低伤害增能压裂液体系:既能在地层条件下生成大量气体、增压助排,又能在弱酸条件下交联、防止碱敏损害,同时具有低滤失、低残渣、携砂性能好的优点,能够大幅度降低压裂液对储层伤害,现场取得良好应用效果。

Conventional fracturing fluid system has big damage to reservoir in the low pressure, low permeability, water sensitivity reservoirs fracturing, therefore, a new kind of fracturing fluid is developed new type low-damage and energy increasing fracturing fluids system, which can generate autogeneous gases under the condition of the formation, increase the pressure and cleanup, cross-link under the condition of weak acid, prevent the alkali sensitivity damage with low fluid loss, low residue, good proppant carrying capacity, and also can greatly reduce the reservoir damage to fracturing fluid and achieve good application effect.
