Application of persimmon husk extraction in the treatment of oilfield produced water was carried out based on the abundant fruits resources of Shannxi province. Persimmon husk was extracted with water and ethanol, and the extractions were screened as corrosion and bacteria inhibitors. The results showed that the both extractions are effective for corrosion inhibiting, and he extraction of water is more potent than that of ethanol. The extraction of water is active against sulfate reducing bacteria (SRB), but inefficient against iron bacteria (IB) and total general bacteria (TGB), while the extraction of ethanol is inefficient against the three oil field micro-organisms.
