| titleOfInvention | Oil-well cement additive against carbon dioxide corrosion as well as preparation method and application thereof |
| abstract | The invention provides an oil-well cement additive against carbon dioxide corrosion as well as a preparation method and application thereof, relating to the field of well cementation of oil-well cement. The oil-well cement additive mainly comprises the following raw materials in percentage by weight of: 20-65%wt of volcanic gray minerals, 2-25%wt of silica fume, 5-25%wt of aluminum salt mineral, 5-35%wt of organic paraffin material, 1-10%wt of methyl silanol sodium, and 3-25%wt of slag. When 15-60 parts of the oil-well cement additive is added into 100 parts of cement, the compactness of cement columns can be strengthened, with low gas permeability and strong resistance against carbon dioxide corrosion. The oil-well cement additive is suitable for different temperatures, and has wider application. |
