| 摘 要： | 适合于复合驱的防腐垢剂BH是一种磷硅酸盐。针对矿场实际，通过室内实验，对含该防腐垢剂的三元复合体系基本性质进行了研究。结果表明，这种磷硅酸盐防腐垢剂具有良好的缓蚀防垢效果，且驱油体系与渤海油田原油仍然可以形成超低界面张力。体系的表观黏度和界面张力的稳定性也有所改善。压力传导和转向调44能力实验结果表明：“聚合物／BH助剂”和“聚合物／表面活性剂／BH助剂”复合体系相比聚合物溶液其传导能力分别下降了14．2％和29．5％，转向调剖能力分别提高了11．8％和14．9％；而“聚合物／ga活性剂／BH助剂”相比“聚合物／表面活性剂／NaOH”体系传导能力相差不大，但转向调剖能力相对提高了10％左右。可见BH防腐垢剂不仅具有良好的缓蚀防垢和降低界面张力效果，而且具有较强的转向调剖能力。

| Abstract: | The chemical BH is a phosphorus silicate which could be used to control corrosion in enhancing oil recovery using ASP technology. According to field facts, the basic properties of the ASP system contained chemical BH were studied in lab in this paper. The results show that the chemical BH has good corrosion inhibition effect and flooding system and oil from Bohai oilfield can form super-low interracial tension. Apparent viscosity of system and stability of interracial tension is also improved. Pressure conduction and steering profile capability experimental results show that conduction ability of polymer/BH additives and polymer/surfactant/BH additives composite system decrease by 14.2 % and 29.5 % than polymer solution; steering profile capability increases by 11.8 % and 14.9 % respectively. While conduction capacity of polymer/surfactant/BH additives composite system is no less than the polymer/ surfactant/NaOH, but its steering profile capability increases by about 10 % relatively. It＇s proved BH corrosion inhibitor not only has good corrosion inhibition and decrease interracial tension effect, but also has strong ability of steering profile capability. |
