摘要
根据深层高温低渗特低渗油藏水力压裂改造需要,开展了耐高温、低摩阻、低伤害压裂液研究,形成了可以满足110℃～140℃储层压裂施工需要的压裂液体系配方,5口井6井次的现场应用表明,施工的成功率和有效率明显提高,压裂施工的摩阻降低、返排率提高、对地层的伤害减少。
Based on the needs of the hydraulic fracturing in deep high temperature reservoir with low porosity,low & ultra-low permeability,a fracturing fluid was studied which had the features of low damage,high temperature resistance and low friction.The fracturing fluid could meet the requirement of 110℃～140℃ reservoir fracturing.The field application in five wells showed that the success ratio,the effective rate and returning rate of the fracturing fluid were greatly improved,at the same time,the friction and reservoir damage were decreased in the process of fracturing.
