Treatment of Aluminum Sulphate Contamination to Water Base Drilling Fluids

  • 摘要: KS19井三开φ311.2 mm井眼在钻至6243~6387 m井段时,使用的高密度KCl-聚磺水基钻井液被含有硫酸铝的清洁化生产用工业废水污染,流变性每日不断呈现上涨趋势至发生突变,一是φ6φ3读值、初切值、动切力均上涨较高,而其他参数均比较正常;二是上水罐、过渡槽钻井液表面粗糙,大量针眼型气泡包裹其中,流态缓慢;三是循环系统加重泵上水困难、泥浆泵抖动严重,泵冲泵压变化较大,钻进期间被迫使用灌注泵辅助泥浆泵上水。分别在套管鞋、井底分2次进行循环调整处理,采用稀释置换、气泡界面张力改变、提高碱度进行中和、流变性改变、提高油含量等至恢复正常钻进,上水罐、过渡槽钻井液仅包裹有少量针眼型气泡,泥浆泵、加重泵上水正常。
