| titleOfInvention | Drilling fluid bionic nano sealing agent and preparation method thereof |
| abstract | A kind of drilling fluid bionic nano sealing agent and preparation method thereof, bionic nano sealing agent is that the raw material matched by following weight is made：60~70 parts of distilled water, 1~2 part of 2 acrylamide, 2 methyl propane sulfonic acid, 20~30 parts of lactic acid, 5~10 parts of crosslinking agent, 0.7~1.5 part of nano titanium oxide, 0.7~1.5 part of molecular weight regulator, the parts by weight of potassium peroxydisulfate 0.1~0.5,0.2~0.5 part of sodium hydroxide.Described crosslinking agent is one kind in GDMA, polyethylene glycol, trimethylolpropane；Described molecular weight regulator is 3 isooctyl mercaptopropionates.Preparation method is comprised the technical steps that：Prepare alkyl based solution；Prepare titanium-based solution；Prepare bionic nano sealing agent.The drilling fluid bionic nano sealing agent of the present invention, solves the problem of Shale Hydration, external water erosion in present drilling process, while the bionic nano sealing agent has stronger biological degradability, effectively reduces the pollution to reservoir. |
