| titleOfInvention | Modified epoxy asphalt, water-based drilling fluid and preparation method thereof |
| abstract | The invention discloses modified epoxy asphalt, a water-based drilling fluid and a preparation method thereof. The modified epoxy asphalt comprises the following components in parts by weight: 100 parts of matrix asphalt, 1-20 parts of a compatibilizer, 1-10 parts of a toughening agent, 5-20 parts of a curing agent, 1-5 parts of a curing accelerator and 5-30 parts of epoxy resin; wherein, the curing accelerator comprises a product obtained by the reaction of polyamine, phenols and aldehyde-containing aqueous solution. The modified epoxy asphalt liquid is added into the water-based drilling fluid, wherein the modified epoxy asphalt has the advantages of small particle size, high softening point, certain elastic deformation capacity and excellent high temperature resistance, and the drilling fluid has good rheological property and high-temperature and high-pressure fluid loss reduction effect when used at high temperature. |
