摘要
我们首先选取了一些表面活性剂和胺类化合物进行了防盐实验。筛选出几种有效试剂,调整比例复配,进行防盐实验,确定出最佳配比。当防盐抑制剂配方为160 mg/L防盐剂A+140mg/L防盐剂B+260mg/L防盐剂C时,王4新斜11-4C地层水中无氯化钠结晶体析出。这种药剂用量小、开发成本低,且能达到显著的抑盐效果,从而对油田清防盐具有一定的指导作用。
At first,the anti-salt experiment of choosing some surface active agent and amine compound was carried out.Screening effective reagent,adjusting the ratio of complex,is for anti-salt experiments to determine the best ratio. When the anti-salt inhibitor formulation is 160 mg / L anti-salt agent A ＋ 140 mg / L anti-salt agent B ＋ 260 mg / L anti-salt agent C,the formation water of Wang four new oblique 11-4C is without sodium chloride crystals precipitated. This reagent small consumption,low cost,and can achieve significant effect of inhibition salt,can also have some instructional effect on how to clean and prevent salt of oilfield.
