| 中文摘要:压裂液和支撑剂是煤层气井压裂增产措施的基本材料。通过实验分析了破胶剂的低温破胶效果，并模拟研究了压裂液对煤的基质渗透率的伤害情况，形成了一整套适合于煤层气井的压裂液体系和配方。确定了用石英砂作为煤层压裂的支撑剂。 |

| Abstract:Fracturing fluids and propping agents are the essential materials for CBM well fracturing to increase yield. Through experiments,analysis is made of the low temperature gel-breaking effect of the gelbreaking agent,the damage of the fracturing fluid to the coal host permeability is modelled,and a complete set of fracturing fluid system and formulation suitable to CBM wells is formed. It is decided that the quartze sand be used as the propping agent. |
