In allusion to corrosion of water reinjection pipeline in Jiangsu Oilfield,electrochemical testing method is used to study and analyze the influence law of factors in temperature,velocity of flow,pH value and NaCl concentration to corrosion.Electrochemical method and coupon weight method are utilized to assess corrosion inhibitors FHH-02,956-02 and BUCT-01.It is indicated that corrosion inhibitors BUCT-01 has a best effect.Corrosion control tests with corrosion inhibitors BUCT-Olare made in two oil wells which are seriously corroded.Test results show that corrosion is effectively inhibited in the water reinjection pipeline and economic benefit is improved afterward.
