| 中文摘要:风化煌斑岩是一种水敏性不稳定地层，钻进过程中常常引起孔壁坍塌，造成卡埋钻等孔内事故。根据风化煌斑岩地层岩性特点及钻进时遇到的问题，对风化煌斑岩地层冲洗液护壁技术进行了大量的试验研究工作，研制了PHP-CORESMART无固相冲洗液。该冲洗液由PHP、Na-CMC和CORESMART等配制而成，是一种具有较强抑制性和成膜性的冲洗液体系，在九瑞矿集区风化煌斑岩地层中应用，取得了比较满意的技术经济效果。 |

| Abstract:The weathered lamprophyre is unstable water-sensitive formation, wall collapse often occurs in drilling process with drilling tools sticking and burying. According to the characteristics of weathered lamprophyre formations and the problems encountered in drilling, experimental study was made on wall protection technology with flushing fluid in weathered lamprophyre formation, and PHP-CORESMART solid-free flushing fluid was developed. The flushing fluid is of strong inhibition and film forming ability being prepared with PHP, Na-CMC and CORESMART, which is applied successfully in weathered lamprophyre layer. |
