| titleOfInvention | High temperature resistance oil base drilling fluid modified fat acids primary emulsion and preparation method |
| abstract | The invention discloses a kind of high temperature resistance oil base drilling fluid modified fat acids primary emulsion and preparation method, high temperature resistance oil base drilling fluid is made of with modified fat acids primary emulsion following component：Dibasic acid anhydride, aliphatic acid and epoxychloropropane, wherein, the mass ratio of dibasic acid anhydride and aliphatic acid is 1:20~1:30, epoxychloropropane is the 15~25% of aliphatic acid quality.The present invention is that aliphatic acid obtains after modification, has stronger emulsifying capacity and high-temperature resistance, while has the function of the high temperature and high pressure filter loss for reducing oil base drilling fluid. |
