摘要
混合液上返速度、密度及机械钻速是泵吸反循环钻进的重要参数，讨论了上述参数的选择、计算与检验。同时讨论了维持液流正常反循环的途径；对钻进中的几个问题提出了看法。
: As lifting speed density of fluid and ROP are the important parameters for pump,
suetion reverse circulation drilling, the paper discusses how to selecting, calculating and inspecting
of these parameters. the paper also discusses the way to maintain noraml reverse circulation of
the fluid and raises views towards these problems.
