Pdc Bit Design

Cost-effective PDC oil drill bit setting Custom processing Manufacturer Pdc Bit Design According to the design requirements, the shallow inner cone is used in this design. According to the characteristics of sandstone formation in Shengli Oilfield, the contour of the crown is designed according to the principle of equal cutting. On the basis of fitting the theoretical curve equation of the contour of the crown, combined with the bit design experience and the bit type Determine the shape of bit crown contour suitable for drilling sandstone stratum: shallow cone, straight line arc crown contour, external cone length is suitable Medium. This kind of straight-line arc profile has the following characteristics: first, to arrange cutting teeth as effectively as possible on the surface of the drill; second, to PDC bit design bit can smoothly transition from nose cutting teeth to diameter maintaining cutting teeth. url:http://www.speedmadedrill.com
