目前常用的冻胶压裂液对基质的渗透率损害在30%以上,而且采用冻胶压裂工艺技术对非常规储层基质渗透率和支撑裂缝导流能力的二次伤害严重,达不到预期的压裂改造效果。通过对滑溜水压裂液进行添加剂优选,对防膨性能、液体伤害、摩阻性能进行研究,最终形成了适合浅井的滑溜水压裂液配方,为同类油气藏的开发提供了宝贵经验。
At present, the commonly used gel fracturing fluid damage to the permeability of the matrix more than 30%, and the use of gel technology fracturing fluid unconventional reservoir permeability of the matrix permeability and secondary support serious secondary damage, not up to The expected fracturing effect. Through the optimization of additives for slickwater fracturing fluid, the research on anti-swelling property, liquid damage and frictional resistance were carried out, and finally a slippery water fracturing fluid formulation suitable for shallow wells was formed, which provided valuable experience for the development of similar reservoirs.
