| 发明名称 | Methods for stabilizing water-sensitive clays | ||
| 摘要 | Methods of stabilizing water-sensitive clays in subterranean formations may include introducing a drill-in treatment fluid into at least a portion of a subterranean formation comprising water-sensitive minerals, where providing the drill-in treatment fluid comprises an aqueous-based fluid and a hydrophobically-modified cationic polymer; and allowing the hydrophobically-modified cationic polymer to at least partially coat the water-sensitive mineral. | ||

| 主权项 | 1. A method comprising: providing a drill-in treatment fluid that comprises an aqueous-based fluid and a hydrophobically-modified cationic polymer, wherein the cationic polymer comprises a quaternary ammonium salt of a polyethyleneimine polymer and wherein the hydrophobic modification on said polyethyleneimine polymer comprises a C5-C18 hydrocarbon comprising an aromatic group; introducing the drill-in treatment fluid into at least a portion of a subterranean formation comprising water-sensitive minerals; and allowing the hydrophobically-modified cationic polymer to at least partially coat the water-sensitive mineral. | ||
