1. PDC bit Description:
PDC called the Polycrystalline Diamond Compact (polycrystalline diamond alloy sheet), these bits for oil drilling in soft formations and the development of new drill. Compared with conventional cone bit, PDC bit with ROP high, wide strata , combinations of features long life, safety factor, auxiliary less time and other advantages. But PDC drilling bits, sand, shale drilling when the difference becomes smaller, the emergence of complex drilling, the drill card layer to bring greater difficulties and PDC drill cuttings small, to some extent, affected the quality of logging debris, thereby affecting the quality of the entire comprehensive logging and oil and gas discovery layer. In addition, different types of PDC bit to adapt to different lithology resistance varied widely, such as improper selection, not only from efficient, fast drilling purpose, but also seriously affect the quality of comprehensive logging. Hejian Baoxing Petroleum Machinery Co., Ltd. is a company specializing in PDC diamond bit production company, PDC drill bit production experience, products sold at home and abroad, by the majority of users praise at home and abroad company: The main production of matrix PDC diamond drill bits and steel body PDC diamond drill bits.
2. PDC drill structural features :
1. carbide matrix drill bit, having a high degree of wear resistance and impact resistance.
2. parabolic crown, maximizing flutes area can effectively clear the bit, increase bit life.
3. Using hydraulic balance design, with five replaceable threaded nozzles, nozzle angle reasonable to obtain the desired bottomhole flow field can be adequately cleaned and cooled cutter, increase cutting teeth life.
4. Asymmetric knife wing, increase drilling balance.
5. For rotary and downhole motor drilling.
Third, the argument
Various models can be customized
