WELL TREATMENT METHODS AND SYSTEMS |
摘要 |
A well treatment method includes drawing a solvent to a first pump, drawing a wetting liquid to a second pump, pumping the wetting liquid through a polymer mixer using the second pump, combining polymer with the wetting liquid to produce a slurry containing undissolved polymer, and combining the slurry with the solvent upstream from the first pump. Another well treatment method includes increasing dissolution time of the polymer by providing a buffering agent in the wetting liquid before combining the wetting liquid and the polymer. A well treatment system includes a polymer mixing subsystem with a mix loop having a mix loop inlet line from a first pump feed line and a mix loop outlet line back to the first pump feed line, the mix loop outlet line containing a polymer mixer. |
