Well bore servicing fluids are provided that include a thermally activated viscosification compound. Further, methods of servicing a well bore are provided that include displacing such a servicing fluid into the well bore, wherein a viscosity of the servicing fluid increases as it passes down the well bore due to its temperature increasing. Thus, the viscosity of the servicing fluid is effective to suspend solids therein when the servicing fluid is in the well bore. The servicing fluid may be, for example, a cement slurry, a drilling fluid, a gravel packing fluid, a fracturing fluid, a completion fluid, or a work-over fluid. In an embodiment, the thermally activated viscosification compound includes at least one water-soluble hydrophobically modified polymer comprising a hydrophobic substituent having from about 1 to about 22 carbon atoms.
所提供的井眼维修液包括一种热激活粘化化合物。此外,还提供了维修井眼的方法,其中包括将这种维修液置换到井眼中,由于温度升高,当维修液沿着井眼流下时,其粘度会增加。因此,当维修流体在井孔中时,维修流体的粘度能有效地悬浮其中的固体。例如,维修液可以是
水泥浆、钻井液、砾石填料液、压裂液、完井液或修井液。在一个实施方案中,热激活粘化化合物包括至少一种
水溶性疏
水改性聚合物,该聚合物包含一个具有约 1 至约 22 个碳原子的疏
水取代基。
