通过实践发现:(1)洗井液中的表面活性剂可以提高金刚石钻进的机械钻速。但表面活性剂和岩石种类不同,其提高幅度也不同;(2)钻速随阴离子表面活性剂(?)电位值的提高而增加;(3)表面活性剂对岩石微裂纹的渗透作用有助于提高钻速。
Through practice, it is found that: (1) Surfactant in the wash fluid can increase the ROP of diamond drilling. (2) the penetration rate of surfactant increases with the increase of anionic surfactant (?) Potentials; (3) the penetration of surfactant into rock microcracks can help To improve the drilling speed.
