The sulfate scale will often lead to fouling in well bore,ground system and water injection stratum,which will bring a great hazard to the production.The status-quo of development of fouling inhibitor for acrylic acid sulfate scale both in China and abroad is described.The main products of homopolymer fouling inhibitor for sulfate scale,the bipolymer fouling inhibitor for sulfate scale,tripolymer fouling inhibitor for sulfate scale and higher polymer fouling inhibitor are introduced.The foulng inhibition mechanisms of fouling inhibitors for sulfate are summarized,such as chelation effect,valve value effect,flocculation and dispersion,crystal distortion,regeneration—self-decomposition de-membraning and working mechanisms of double electric layer.It is pointed out that the polymer inhibitors for sulfate scale have different fouling inhibition mechanisms for barium sulfate and calcium sulfate.The causes of different fouling inhibition mechanisms are studied.
