- Abstract
“Factory” fracturing is the necessary requirement of benefit development in shale gas reservoir, according to the “factory” fracturing requirement, forming a slick water formulation which could meet the request of “factory” fracturing: low molecular weight, low viscosity emulsion friction reducing agent, friction reducing rate is 73%-78%, the dissolution time is less than 30 s, it could meet the high displacement, continuous mixing requirement; and using efficient bactericide, bactericidal rate of sulphate reducing bacteria is 100%, it could effectively reduce the damage to reservoir and production equipment; flowback fluid can be used repeatedly after simple treatment. CNH3 well group field test showed that the friction reduction rate is from 76.2% to 78.7% of slick water; the flowback rate is from 12.16% to 14.30%, the cumulative test production reached 20.95× 104 m3/d.
