| titleOfInvention | Polymer type non-crosslinked self-diverting acidification diverting agent and preparation method thereof |
| abstract | The invention discloses a polymer type non-crosslinked self-steering acidification diverter, which comprises blocks a, b, c and d; wherein, the mol percentage is as follows: 92-96% of a, 0.5-2% of b, 1-5% of c and 0.5-2% of d. The polymer type non-crosslinked self-diverting acidification diverter increases the viscosity of polymer acid liquid through acid salt reaction under the condition of no crosslinking agent, thereby achieving the aim of acidifying stratums with different permeabilities. |
