摘　　要：针对高含硫油田的油井在开采过程中 ,由于温度、压力的变化 ,使原油中的多硫化物析出硫磺 (或游离态硫 )和机械杂质一起形成沉积堵塞而影响油井产量这一矛盾 ,在借鉴和吸收国内外研究成果的基础上 ,结合油田实际研制了溶硫速度快、溶硫量大 ,可燃性低、使用安全、腐蚀性小的DNH -Ⅱ型高含硫油田解堵剂 ,该解堵剂不仅与缓蚀剂具有良好的配伍性 ,而且还能再生循环使用 。During Production of oil well in high sulfur-bearing oilfield,for the variation of temperature and pressure,sulfur or free sulfur is separated from crude.It can form sedimentation together with mechanical admixture to plug reservoir.On the basis of research achievement abroad and in combination with oilfield practice,DNH-Ⅱ type plug removal agent for high sulfur-bearing oilfield is developed.It can quickly solve sulfur and its combustibility and corrosivity are low ect..Meanwhile,the plug removal agent has good compatibility with corrosion inhibitor,in addition,it can be regenerative cycle application and has higher application value.
