固体阻垢剂ZGJ-1的室内研制

INDOOR RESEARCH ON SOLID SCALE INHIBITOR ZGJ-1

针对油田结垢特点和液体阻垢剂存在间歇注入、加药不均匀、药效短、消耗大和效果不稳定等缺点,室内合成了母体阻垢剂,研制筛选出了增效剂、粘合剂的配方,固体阻垢剂ZG J-1的成型方法和工艺,建立了固体阻垢剂平均溶解速率及溶出率的评价方法,80℃时静、动态平均溶解速率分别为0.130 8、0.159 2 g/d.cm2,在加药量为10 mg/L时对油田污水的阻垢率达到98.9%。现已在胜利油田推广应用。

There are some defects to liquid scale inhibitor,such as interval injection,chemical feed fluctuation,short-effect,high consumption and unstable effect,aiming at the defects,the main parts of scale inhibitor are synthesized and then the proportion of synergist,binder and additive decided,molding methods and processes studied.A method is established to evaluate the average dissolution rate of the solid scale inhibitor under the conditions of 80℃,average static dissolution state is 0.1308g/d cm2 and dynamic dissolution state is 0.1592g/d cm2.The inhibition effect can reach 98.9% when the concentration is 10 mg/L.Solid scale inhibitor ZGJ-1 has been used in Shengli Oilfield.
