摘要: 针对渤海QHD32-6油田钻井中钻屑形成泥球的突出问题,依据钻屑形成泥球的原因分析,采用粘结法、全角滚动法等实验方法,评价了自己研制的“FNJ-1”型防粘结剂的抑制钻屑粘结作用效果,并应用该剂于渤海QHD32-6油田上百口井的钻井试验中,取得抑制钻屑形成泥球的显著效果。

Abstract: Aimed at the outstanding problem that drilling cuttings form mud balls during drilling operation in Bohai oilfield and based on analyzing the reason of formation of mud balls, a new type of anti-binding agent FNJ-1 has been developed. Results show that remarkable success has been gained in inhibiting drilling cuttings bonding when using FNJ-1 in several hundred
wells of Bohai QHD32-6 oilfield.

Key words: directional well, drilling cuttings, mud balls, anti-binding agent
