Synthesis of Poly-phosphate Acid-washing Inhibitor and Its Application

This paper evaluates the important role of existing inhibitors in oil and gas exploration,drilling,production, and pipeline engineering, briefly states the development trend of green inhibitors in recent years,and in troduces the method of synthesizing novel poly-phosphate acid-washing inhibitor taking the polyatomic alcohol and poly-phosphoric acid as its major crude materials, and the optimal conditions of synthesizing the inhibitor obtained through a large number of experiments. In light of the operating environment of oil/ gas pipeline,the method of evaluating the effect of the novel inhibitor under the condition of strong acid by use of the blade -hanging experiment is introduced in the paper. According to the inhibiting mechanism of poly-phosphate, thepossible influence of synergistic effect upon its inhibiting result is discussed, the superiority of the novel inhibitor is summarized and the imagining of improving its inhibiting redult is proposed by the authors
