低渗透裂缝性油藏弱凝胶的室内评价研究

Laboratory evaluation of weak gel in low permeability fractured reservoirs

基于WJN-弱凝胶最佳配方的基础上,通过室内评价表明:该凝胶在低于85℃内有较好的成胶效果和耐老化性,可以实现多尺度、深部调剖,有较好的经济性。

Based on the best formulation of WJN-weak gel,the laboratory evaluation shows that the gel has good gel forming effect and aging resistance at less than 85 degrees,and can achieve multi-scale and deep profile control.
