摘要
为有效的利用脱色膨润土,将其变废为宝,本文研究了用脱色膨润土制得石油钻井泥浆的新工艺。且为提高石油钻井泥浆的润滑性,本文还探讨了制备乳化石蜡的工艺条件:采用复配乳化剂span80+tween80,乳化助剂为异戊醇,在85℃、800r/min的条件下乳化35 min可制得稳定性较高、分散性较好的乳化蜡。将乳化蜡加入乳化后的脱色膨润土泥浆中,添加量为泥浆质量2%时,泥浆的润滑性能提高54%。
In order to use bleaching bentonite effectively,this paper research the new technology which oil drilling mud was made from bleaching bentonite.In order to improve the lubricity of the oil drilling mud,this article also discuss process conditions of preparation of emulsified wax: Emulsifiers were span80 +tween80,emulsifying additive was Isoamyl alcohol.The emulsifying temperature was 85℃,stirring speed was 800r/min,emulsifying time was 35min.Under these conditions,higher stability,better dispersion of the emulsifying wax was made.Paraffin emulsion was added into the oil drilling mud,mud lubrication was improved by 54% when the amount of paraffin emulsion was 2% by wax weight.
