Abstract: In order to determine the possibility of prepare fracturing fluid using treated acidizing flowback fluid in Tarim Oilfield, which includes complicated composition, high oil, metal ions and acids, one set of processing containing" filter-chemical precipitation-flocculation sedimentation-preparation fracturing fluid" was put forward through the analyzing of flowback water quality in this paper. Filtration was done to remove oil and lumps by filter cloth because a large number of oil affects the swelling and crosslinking of fracturing fluid. Metal ions were precipitated and residue acids were neutralized directly by sodium carbonate in order to eliminate the bad influences of high metal ions affecting the guar molecules stretch and the carrying sand performance of fracturing fluid. It needs further flocculation treatment by flocculant to despite the small particles impurities from acidizing flowback fluid after simple processing. Finally, the flowback fluid was used to prepare fracturing fluid under neutral or weak acid conditions to prevent environmental pollution and alleviate the problem of water shortages in Tarim Basin. The experiments showed that the removal rate of suspended solids reaching 98% and the average diameter distribution was 2.36μm when the precipitant was 145 mg/L and flocculant was 1 000 mg/L. The suspension performance of fracturing fluid prepared by treated acidizing flowback fluid was great and its rheological property and viscoelasticity were similar to the fracturing fluid prepared by tap-water, and also met the standard SY/T 6376-2008 General Technical Condition of Fracturing Fluid. It could satisfy the require of high temperature and high shear in ultra deep well in Tarim Basin. In short, the research showed that the recycle process of acidizing flowback fluid could be achieved.
