Weighted fracturing fluid is one of the effective means to solve the too high pressure problem during the process of fracturing operation. However, the common weighted gel fracturing fluid has some disadvantages, such as high residue content, huge tube frictional resistance, low shear resistance, etc. At the same time, most of clean fracturing fluid can not be used at high temperature. To solve the above problems, a novel weighted fracturing fluid (WFF) that the density reached to 1.3 g/cm3 and more and the temperature-resistant was 140℃ was investigated. The formula of the WFF was established as follows: 0.6% thicker GRF-1H, 0.3% thickening additive GRF-2 and 37.05% weighting agent JZ12. The dynamic sand-carrying properties, temperature and shear resistance proerty, filtration performance and fracture conductivity of the WFF were evaluated. The experiment results showed that as long as the viscosity reached up to 22 mPa·s, the WFF could possess a good sand-carrying performance. High-temperature rheologic tests showed that the WFF system has good temperature and shear resistance property. With the increase of density, there was a significant thickening effect of salt. The static filtraition performance of the system was evaluated using real cores. The WFF system did not contain water insoluble but it had low filtration coefficient. The damage of the WFF on the fracture conductivity was only 8.94%, which was far less than that of boron crosslinked HPG fracturing fluid.
