| titleOfInvention | A kind of oil-based plugging fluid loss reducer and preparation method thereof |
| abstract | The invention discloses an oil-based plugging fluid loss reducer and a preparation method thereof, and relates to the technical field of treatment agents for drilling fluids. The problem of poor blocking effect. An oil-based plugging fluid loss control agent, comprising the following components in parts by weight: 35-45 parts of asphalt compound, 25-35 parts of resin material, 3-7 parts of caustic soda, 20-25 parts of rock asphalt, 2-3 parts of multifunctional composite agent, 0.2-1.5 parts of surfactant, 4-6 parts of organosilicon, and 2.5-4.5 parts of sodium dodecyl diphenyl ether disulfonate. The oil-based plugging fluid loss reducer in the present invention has good salt resistance after use, and can further exert a good plugging effect in the drilling construction process. |
