聚丙烯酰胺泥浆,一般简称PAM泥浆,具有比重低、粘度低、固相含量少的特点,并有一定的剪切稀释作用,宜于在小口径金刚石钻进中应用.我们是在湖南某矿区试验的,那里的地质条件是,湘南二叠纪煤系地层,大段结核泥岩和厚煤层,地层松软,并且倾角大,遇水膨胀,坍塌掉块严重.在九个月的试验中,打完了十五个钻孔,证明PAM泥浆对施工具有很大的促进作用.
Polyacrylamide mud, generally referred to as PAM mud, with low specific gravity, low viscosity, low solid content characteristics, and have some shear dilution, suitable for small diameter diamond drilling application. We are in a mining area in Hunan Test, where the geological conditions, the southern Hunan Permian coal-bearing strata, a large section of nodular mudstone and thick seam, stratum soft, and the inclination angle, swelling with water, collapsed block serious.In a nine-month trial, the fight Fifteen holes were drilled to prove that PAM mud had a great promotion effect on construction.
