Methods for reducing a viscosity of a viscosified fluid include reacting, such as by depolymerizing and/or decomposing, a polymeric material of the viscosified fluid with a breaking agent including a fully coordinated transition metal compound, such as a strongly complexed fully-coordinated transition metal compound. The methods of treating the subterranean are provided that include reacting, such as by depolymerizing and/or decomposing, a polymeric material of a viscosified treatment fluid with a fully coordinated transition metal compound, such as a strongly complexed fully-coordinated transition metal compound, to facilitate breaking of the viscosified treatment fluid after the fracturing or treatment is finished.
降低高粘度粘化流体的方法包括使用断裂剂,如含有完全配位的过渡金属化合物,例如强配位的完全配位过渡金属化合物,与粘化流体的聚合物材料反应,例如进行去聚合和/或分解。提供了处理地下岩石层的方法,包括使用完全配位的过渡金属化合物,例如强配位的完全配位过渡金属化合物,与粘化处理流体的聚合物材料反应,例如进行去聚合和/或分解,以便在压裂或处理完成后使粘化处理流体破裂。
