| 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 prob-lems 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 in-hibition and film forming ability being prepared with PHP, Na-CMC and CORESMART, which is applied successfully in weathered lamprophyre layer. |
