| titleOfInvention | A kind of preparation method of multi-functional high temperature resistant drilling fluids inorganic agent |
| abstract | The invention discloses a kind of preparation method of multi-functional high temperature resistant drilling fluids inorganic agent, inorganic agent is with AMPS, DMC and humic acid are raw material, prepared by graft copolymerization and metathesis reaction, the inorganic agent has excellent filtrate reducing effect and rejection, room effect evaluation shows, normal temperature and pressure filter loss when product dosage is 0.5% is 0.4mL, HTHP filtrate reducing amount is 2.2mL, anti-dilative has reached 46.86%, its filtration reduction and rejection are no less than even better than domestic and international individually fluid loss additive and inhibitor, and product is resistant to 160 DEG C of high temperature, it can be widely applied to oil drilling field. |
