摘要
在浅海岸边进行钻机作业,由于海平面水位不稳定,采用6BS反循环泵已不合适。在工作实践中,将原施工工艺改进为气举反循环,此方法不仅没有降低原钻机的施工性能,而且快捷、方便,经济效益显著。
Due to unstable sea level, drilling by using 6BS counter circulation pump is not very suitable. In practice, the former technology is changed to counter circulation. This method is quick, facilitate and evident economic effect.
