高阶煤压裂液伤害机理研究

Study on Damage Mechanism of Fracturing Fluid in High Rank Coal

为了分析压裂液对高阶煤层压裂后产能的影响,从压裂液对高阶煤的伤害研究入手,结合沁水盆地七元矿区的实际压裂情况,采用压裂液伤害实验与电镜扫描分析相结合的方法,研究了不同类型压裂液对高阶煤岩的伤害原因,进一步揭示了压裂液对高阶煤岩的伤害机理。

In order to analyze the effect of fracturing fluid on the fracturing productivity in high rank coal seam, starting from the research on the damage of fracturing fluid to high rank coal seam, combined with the actual fracturing situation of Qiyuan mining area in Qinshui basin, using the method of fracturing fluid damage experiment and electron microscopy scanning analysis, analyzed the reasons of different types of fracturing fluid to high-rank coal,and further revealed the mechanism of fracturing fluid to high rank coal seam. damage damage .
