1/1/2018, · In addition, the system can be continuously mixed to shorten the, fracturing cycle, and can carry acid (HCL and HF) of concentration 1%-9% and organic acid 1%-3%, to achieve combination of acidizing and sand fracturing. The, flow-back liquid, can be recovered directly, and the same thickener can be, recycled, and reused.

The efficiency of the Fe 0 /H 2 O 2 process after acidification increased with the reagent dose. The best efficiency was obtained for an Fe 0 /H 2 O 2 reagent dose ratio of 8000/9200 mg/L, which removed 294 mg/L to give a final value of 499 mg/L. That achieves a total TOC removal of 53% by the acidification process followed by the Fe 0 /H 2 O 2 process.
