摘要
适合冀东油田气温的液体ET24润滑剂以动植物油、淀粉等为主要原料合成。室内评价结果表明,ET24润滑剂荧光级别为3级,EC50值为216000mg/L,达到无毒标准,较好地保护了环境。ET24润滑剂在冀东油田的T30-1井、高12-3井等14口直井、大斜度井和水平井的现场应用结果表明,ET24润滑剂能降低钻井液滤失量,润滑性能好,荧光级别低,可有效降低摩阻、减轻钻机负荷,机械钻速快,起下钻和完井作业正常,并与水基钻井液配伍性很好,可满足不同井型提高钻井液润滑性的需要。
A liquid lubricant,ET24,which is suitable for use in Jidong oilfield was synthesized using animal and vegetable oils and starch.Laboratory studies showed that ET24 has a fluorescence level of 3 and an EC50 of 216 000 mg/L.Application of this lubricant in 14 vertical wells such as T30-1,Gao12-3,and deviated and horizontal wells showed that ET24 had good lubricity,low fluorescence level and good compatibility with other commonly used mud additives.
