| titleOfInvention | A kind of preparation method of low-temperature demulsifying agent and the low-temperature demulsifying agent prepared by this method |
| abstract | The low-temperature demulsifying agent prepared the invention discloses a kind of preparation method of phenol amine aldehyde block polyether low-temperature demulsifying agent and by this method, the method carries out polycondensation to aldehydes matter, amine substance and aldehyde material first and prepares phenol amine aldehyde resin, and final products then are obtained by the reaction with epoxide again.The advantages that demulsifier that preparation in accordance with the present invention is prepared has alkali solubility good, and clear water effect is good, has no irritating odor, and onsite application facilitates.Most suitably used temperature is 45 DEG C, but still has preferable effect when down to 41 DEG C.The excellent demulsification of the demulsifier, situation big to shallow-layer crude oil low temperature Produced Liquid demulsification difficulty, after demulsification more than water phase oil content have excellent effect, situation big suitable for Produced Liquid demulsification difficulty under low temperature, after demulsification more than water phase oil content. |
