摘要
压裂液对储集层的伤害通常是利用岩心伤害来确定的。文章通过核磁共振的方法,采用真实砂岩并以甘油水合物溶液模拟不同粘度的压裂液,分析研究压裂液粘度对束缚水增加伤害程度和两相流伤害程度的影响。为降低压裂液对特低渗透储层压裂改造过程中的储层伤害提供了一定的技术支持。
The fracturing fluid to the reservoir of the damage is usually determined using core damage.In the paper,Nuclear Magnetic Resonance(NMR) methods,using real sandstone and glycerol hydrate solution to simulate different viscosity fracturing fluid,the viscosity of the fracturing fluid analysis of bound water increases the degree of injury and damage of two-phase flow effects.To reduce the fracturing fluid to the low permeability reservoirs in the process of reservoir fracturing damage provided some technical support.
