Drilling wells Shenzhen Shenzhen Shenzhen drill wells selection and classification of two hundred meters of water a day to three days every day, 356 days a year and water well drilling company in Shenzhen diamond material should recover stratigraphic drill natural diamond bit cutting structure different choice size of the diamond, with different densities and cloth fabric teeth tooth manner, to meet the needs of medium to hard formation drilling. TSP drill suitable for medium to hard formation drilling abrasive nature. PDC drill suitable for soft to medium-hard formations, but PDC drill stratigraphic drilling must be homogeneous formation, in order to avoid the impact load, including gravel formations can not use the PDC drill bit. With the development of synthetic diamond material technology and drill technology diamond drill material will expand the scope of application. Table 2-5 for Christensen Company diamond drill material selection guide, this table is a summary based on a lot of use out of the experience. This form can be a general understanding of the various types of diamond drill adapt material formation.
