| titleOfInvention | A kind of viscoelastic surfactant for high temperature self-steering acid, preparation method and application |
| abstract | The invention discloses a viscoelastic surfactant for high-temperature self-steering acid, and its structural formula is as follows: Wherein, n is a saturated alkane with 2 to 8 carbon atoms, R 1 is a saturated or unsaturated alkane with 18 to 28 carbon atoms, R 2 and R 3 are independently methyl, ethyl, and hydrogen atoms, and R 2 and R 3 can be the same or different, and X- is any one of Cl- , Br- , F- , CO 3 2- , SO 4 2- , HCOO- , CH 3 COO-. The preparation method of the surfactant is as follows: it is made of fatty acid and organic amine through acid-amine condensation reaction to generate intermediate product, and then reacts with metal hydride to generate fatty amine, and then adds acid solution to protonate it, so as to obtain ultra-long chain viscosity Elastic cationic surfactant. The present invention also provides the application of the surfactant as a thickening diverting agent for self diverting acid. The surfactant of the present invention can be used as a self-steering acid of a thickening and diverting agent at a high temperature of 150° C., and has the advantages of stable structure, thickening of acid solution, uniform acidification and self-steering. |
