Reverse Circulation Drilling Rig Truck-Mounted Water Well Drilling Rig

Product Description

Product Description

  JZF-D positive and negative circulation drilling rig is a crawler type drilling rig that integrates positive circulation and reverse circulation drilling functions. The positive circulation is mainly used for drilling sandy soil, and the reverse circulation is mainly used for slime or pebble. This drilling rig can easily handle the drilling of soil, sand, slime, and pebble layers. It has been widely used in drilling wells, farm irrigation wells, and engineering pile holes.

  Features: Fast drilling speed. Due to the high rising flow rate of the flushing fluid in the drill pipe and the strong slag discharge capacity of the pipeline, the cuttings and pebbles in the well can be directly extracted out of the well. Therefore, there is little accumulation of cuttings at the bottom of the well, which greatly reduces the number of repeated grinding and crushing times. Reverse circulation drilling relies on the static pressure and osmotic pressure of the flushing fluid to keep the hole wall stable and reduce the blocking of the aquifer in the well by the mud. Therefore, it is easier to clean the well and the water output after the well is completed is larger.
