摘要：
The invention discloses treatment and reuse of oilfield produced water. A method of inhibiting enzymes/bacteria in an aqueous medium for viscosification comprises contacting the aqueous medium with a denaturant and/or a bactericide and thereafter mixing a gelling agent in the aqueous medium. The viscosified fluid can be used as a well treating fluid for fracturing and other applications. A well treatment fluid comprises a metal denaturant and/or a bactericide and a gelling agent in an amount effective to viscosify the fluid. Also disclosed is oilfield produced water denatured with from 1 to 2000 ppm by weight of a zirconium compound.
摘要（中）：
本发明公开了油田生产用水的处理和再利用。 在水性介质中抑制酶/细菌进行增粘的方法包括使水性介质与变性剂和/或杀菌剂接触，然后将胶凝剂混合在水性介质中。 稠化流体可用作压裂和其他应用的良好处理流体。 良好的处理流体包含金属变性剂和/或杀菌剂和胶凝剂，其量有效地使流体粘稠。 还公开了以1至2000重量ppm的锆化合物变性的油田生产的水。
