| titleOfInvention | A kind of air-mist drilling cationic polymers anti-sloughing agent |
| abstract | The present invention relates to a kind of air-mist drilling cationic polymers anti-sloughing agent, by organic amide class monomer A, N substituted amide class monomers B, cationic monomer C by (60 ~ 80): (10 ~ 20): the mass percent of (10 ~ 20), under the effect of initiator and pH value regulator, copolymerization forms.Preparation technology of the present invention is simple, easy to operate, products obtained therefrom 0.5% aqueous solution 72h bis-shale recovery ratio are greater than 90%, saturated extent of adsorption is greater than 100.0mg/g, product has the ability of high inhibition, strong absorption, as the anti-sloughing agent of Atomized drilling fluid, effectively can suppress the hydration swelling of mud shale, improve air-mist drilling borehole wall stability, extend the atomization safe operation time, give full play to air drilling advantage. |
