several problems have long existed in continuous preparation and injection of fracuturing fluid with dry thickening agents. Those problems include dusting, non-homogeneity of the fracturing fluid (such as generation of solid particles and gel congolmerates of dry thickening agents when dissolving in water ), and long dissolution time of thickening agnets etc. Based on the application of BCG, a mature supramolecular polymer thickener, a thickener was developed, which was composed of liquid paraffin, methanol, emulsifier, dispersant and thickener. The performance test shows that the hydration time of the thickener is only 0.8min, and there is no "fish-eye" in the dissolution process, so it can be prepared quickly in the field. Preparation of fracturing fluid has good heat resistance shear reisstance ability, when using a concentration of 1.6%, constant temperature under 170℃, 170S-1 shear 2 h, final viscosity stability at around 40 mpa s, in addition, the fracturing fluid has excellent suspended sand performance, and under the condition of different temperatures can be completely break. The breaking fluid has low surface tension and residue content. The properties of the fracturing fluid prepared by the thickener are equivalent to the fracturing liquid phase prepared by the dry powder thickener.
