SPT-1500 water well drilling rig is characteristic by trailer, rotary table rotation, forward and reverse circulation. 
It is mainly suitable for drilling in unconsolidated formation, sand, gravel layer, bedrock and other complex 
formations which belong to Quaternary strata. The drilling depth can reach to 1500m. It also can be applied to 
the drilling operations of hydrogeological prospecting, geothermal development and pouring pile of engineering 
construction,etc. 
This drilling rig is a mechanical transmission rotary table drilling rig, suitable for both forward and reverse 
circulation drilling processes. It is easy to operate, has a large drilling capacity, is easy to disassemble and 
maintain, has a wide range of uses, and strong practicality. It has the advantages of compact structure, 
smooth transmission, reasonable material selection, durability, and low operating cost. It can also achieve 
mechanical loosening and unloading of drilling tools.
