| titleOfInvention | Foam reinforcing agent for micro-bubble drilling fluid and preparation method and application thereof |
| abstract | The invention provides a foam reinforcing agent for micro-bubble drilling fluid, which comprises a compound with a structure shown in a formula I. The foam reinforcing agent provided by the invention has lower relative molecular mass, has good surface activity and lower steric hindrance, can be used for synergistic action with a surfactant in drilling fluid, increasing the arrangement density of the surfactant on a microbubble wall and the microbubble wall thickness, improving the air core sealing property in the microbubble, enhancing the stability and the compression resistance of the microbubble under the conditions of high temperature and high pressure, preventing air from escaping from the microbubble under the conditions of high pressure at the bottom of a well, and improving the leakage-proof performance of the microbubble drilling fluid. The invention also provides a preparation method and application of the microbubble drilling fluid foam reinforcing agent. |
