HETEROGENEOUS PROPPANT PLACEMENT |
| 摘要 |
A method for forming proppant aggregates, for example downhole in an injection well, includes injecting a slurry including a thermo-responsive polymer with a low critical solution temperature and a proppant downhole, and heating the slurry above the low critical solution temperature of the polymer. The heating of the slurry above the low critical solution temperature of the polymer aggregates the proppant. A composition of the slurry includes a carrier fluid including a thermo-responsive polymer, a proppant, and optional additives. |

1. A composition comprising:
a carrier fluid including a thermo-responsive polymer; a proppant; and optional additives,
wherein the polymer has a low critical solution temperature, wherein
at or below the low critical solution temperature, the polymer is soluble in the composition; andabove the low critical solution temperature, the solubility of the polymer in the composition decreases and the proppant forms aggregates. |
