| titleOfInvention | Drilling fluid treating agent and preparation method thereof |
| abstract | The invention discloses a drilling fluid treating agent and a preparation method thereof. The treating agent is prepared from the following raw materials: 100 parts by weight of water; 15-30 parts of monomer; 25-30 parts of monomer; 32-13 parts by weight of monomer; 42.5-7.5 parts by weight of monomer; 10.05 to 0.4 weight portion of initiator; 20.025-0.2 parts by weight of initiator; 2.5-5.0 parts of pH regulator; the drilling fluid treating agent has good effects of reducing filtration, lubricating and inhibiting mud shale expansion, has the temperature resistance of 130 ℃, has the characteristics of small addition, filtration loss reduction, lubrication and high inhibition efficiency, and can meet the requirement of drilling in a well section with the formation temperature of 130 ℃. |
