Connecting convenient, with the characteristics of light weight, high flexibility, not easy to bend, compared with other drill pipe, has the advantages of easy operation, high speed of drilling, so called the efficient screw drill pipe. Efficient spiral drill pipe widely used in drilling in the coal seam and near coal seam geological conditions, the coal mine to explore the water and gas drainage borehole construction, can also be used for anchorage, drilling, construction and other fields of geophysical prospecting and construction of water conservancy projects, water type and the barrier of water-saving.
