可直接混配的海水基变黏压裂液及其制备方法
摘要：
本发明属于压裂液领域，具体涉及一种可直接混配的海水基变黏压裂液及其制备方法。压裂液包括海水基滑溜水压裂液以及海水基高黏滑溜水压裂液；海水基滑溜水压裂液包括下述组分，以海水基滑溜水压裂液总量计，增稠剂占0.05％-0.15％，0.01％-0.03％增效剂，杀菌剂0.1％-0.2％，余量为海水；本发明解决了海上压裂由于储水空间有限，导致压裂规模小，压裂效果不理想的难题。海水资源丰富，压裂施工时现配现用，有效降低了压裂液用水及储运成本，大幅缩短施工周期。
摘要（英）：

Belonging to the field of fracturing fluid, the invention particularly relates to a directly blendable seawater-based variable viscosity fracturing fluid and a preparation method thereof. The fracturing fluid comprises a seawater-based slickwater fracturing fluid and a seawater-based high-viscosity slickwater fracturing fluid; the seawater-based slickwater fracturing fluid comprises the followingcomponents, in terms of the total amount of the seawater-based slickwater fracturing fluid, 0.05%-0.15% of a thickening agent, 0.01%-0.03% of a synergist, 0.1%-0.2% of a bactericide and the balance seawater. The invention solves the problems of small fracturing scale and unsatisfactory fracturing effect caused by limited water storage space in offshore fracturing. Seawater resources are rich, thefracturing fluid can be prepared and used immediately during fracturing construction, thus effectively lowering the water consumption, storage and transportation cost of the fracturing fluid, and greatly shortening the construction period.
