由于定向井,水平井可以使油管有角度的进入油层,增加了油层的裸露面积,大幅度的提高了单井采收率,达到提高油田开发效益的目的,因此,直井越来越少,定向井,水平井成为油田开发的主要技术手段,所以迫于生产的需要本单位海蓝无线,GEOLINK负脉冲,普利门负脉冲数量均有大幅度增加,由于仪器增多,为了施工顺利,增加仪器下井成功率,减少仪器顺坏,应对仪器的安全问题给与重视。
Solidification is one of the most popular methods for chromium-contaminated drilling mud treatment.The article described the solidification method and its influencing factors for the waste mud treatment in the west of Sichuan Province.In the experiments cement,lime,aluminum chloride polymer and sodium silicate were selected as the solidification reagents.The ratio of the mixtures,mixing procedure,solidification time and pH value were considered as the main factors controlling the solidification effect.The orthogonal experimental results showed that the optional method for drilling mud solidification might be adjusting the mud water content to 46%,then adding cement,lime,aluminum chloride polymer and sodium silicate with a ratio of 10%,1%,3% and 0.5% respectively with 72 hours solidification.The leaching test revealed that this solidification methods can remove 93% Cr(Ⅵ)and 95% total Cr from the mud compared with the untreated,which meets the standard of GB/T14848-9 and GB5085.3-1996.
