摘要
报导了一种新型的水溶性无萤光石油钻井液润滑剂ＨＰＮＢＰ，该润滑剂含有水溶性基团：－ＣＯＯＨ，－ＯＨ，－ＣＯＮＨ２和抗磨活性元素Ｐ，Ｂ．它以０．５％的量加入基浆中，润滑系数降低率高达９５％，扭矩（８０Ｎ）降低率大于５０％，极压膜强度高，热稳定性好，并具有良好的耐盐性，与其它常用的泥浆添加剂有很好的配伍性。是一种适用于深井、定向井、水平井、探井等钻井液的高性能润滑剂。
A new-type water-sluble non-fluorescent lubricant for drilling muds has been devel-oped.It contains the water-soluble groups一COOOH,-OH,-CONH2 and anti-wear activeelements(phosphonium and boron ).It possesses excellent lubricity and extreme pressurepreperty.Its percentage reduction of friction coefficient can be as high as 95%and that oftorque is higher than 50%,Its extreme pressure film is of very high strength and good ther-mal stability and it is well compatible with other commonly used mud additives.
