| 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. |
