Combining the production and scientific research, 8 water wells were constructed with normal circulation drilling method and 11 water wells were constructed with pump suction reverse circulation drilling method in groundwater resource region along the Yellow River in Zhengzhou. By the analysis on the efficiency and economy of these 2 different drilling technologies, the conclusions were got: in groundwater resource region along the Yellow River in Zhengzhou, the best well depth should be smaller and larger than 140.75m respectively with pump suction reverse circulation drilling method and with normal reverse circulation drilling method each. The conclusions can be the reference for water well construction in the similar area.
