TREATING WELLS WITH ION-EXCHANGE-PRECIPITATED SCALE INHIBITOR |
| 摘要 |
The scaling of a production well in a clay-containing reservoir is inhibited by injecting a scale inhibitor dissolved in an aqueous solution having a pH and ratio of monovalent-to-multivalent cations such that multivalent cation salts of the inhibitor are precipitated as a result of a cation-exchange within the reservoir. |
