Association polymer fracturing fluid system.Its preparation method is under circulation or blender stirring condition, in crude oil extraction sewage
It is slowly added to thickening agent, metal ion stabilizing agents, Waterproof lock agent, high-temperature stabilizer, clay stabilizer by above-mentioned concentration, is sufficiently followed
Ring or stirring obtain fracturing fluid stoste to thickening agent complete swelling.But this method is not able to satisfy construction well site and matches to fracturing fluid
Massive hydraulic fracture job requirements i.e..
Another existing literature provides a kind of fracturing fluid and its preparation method using fracturing outlet liquid preparation, the preparation
Method is that the special modification that mass fraction is 0.35~0.45% is added into fracturing outlet liquid in whipping process to return drain use
Guar gum sequentially adds the expansion-resisting agent that mass fraction is respectively 0.3~0.5% after stirring 5min, 0.3~0.5% cleanup additive,
0.1~0.3% fungicide obtains stoste after mixing evenly, stands 30min.This method time of repose is too long, is not able to satisfy and applies
