With the development of drilling technology, oil fields are challenging for deeper and more complex stratigraphic constantly. SICHUAN CHUANGSHI CHRIDA DIAMOND BIT CO.,LTD. following the tradition of continuous innovation, carried out in-depth researches on the mechanical properties and bit failure mechanism when drilling the deep hard rock bedding, introduced a new generation of PDC bits - "CK" series drill bits, which can work in the complex formation of dense and high abrasive. |
| |
Gold Series bit is a premium line of CSC PDC bits with features that optimize both bit durability and rate of penetration. After many years of research on the rock, cutting mechanics and residual stress into a cutter during the manufacturing process, Hughes Christensen's engineers developed new patented diamond cutter technology, which is the foundation of Gold Series PDC bits. |
| |
BD series (Black Diamond) technology is developed on the basis of “G” series, which extended PDC bits application range. So far, BD series have been widely used in the domestic and international oilfields.“BD” series is a premium line for multiple applications, which is tailored to meet the requirement of specific formation and actual drilling conditions. The design adopts the “Total Balance” concept to obtain the optimum hydraulic effect. The super anti-wear gauge and streamlined geometry make the bit more ideal. |
| |
STR series is a type of PDC bit especially designed for the slim hole. Specific cutters layout and patented cutters application improved bit working life. With its reasonable design of the back rake angle of the cutters , which reduced the bit torque and improved the bit orientation ability. |
| |
After years of research work, CSC engineers developed new types of “GS” series steel body PDC bits on the basis of successful type of “G” series. This line is further optimized by adopting the theory of force balance, hydraulic balance and cuttings removal balance. |
| |
Chipmaster series usually drill in the soft and sticky formation where bit balling often occurred. This type features of specific geometry shape and hydraulic jetting, which improved the cuttings disposal and optimized the bottom hole cleaning. The patent cutters broadened the application range. |
| |
Impregnated Bit (S series) is a premium line of specific diamond bits which utilizes hot pressed segments. This type extends the application of diamond bits, especially in the extremely and highly abrasive formation.
Unique Shape |
| |
D series bit adopt the superior natural diamond cutters to sinter furnace on the erosion-resistant bit body. It penetrates in the high abrasion formation by plough or shear, for example in the granite and quarts drilling. |
| |
CSC's core bit use tungsten carbide matrix with a steel skeleton in it. The bits adopt parabolic, double cone, tapered step crown profile, and diamond inner and outer gauge. |
| |
RWD is a patent tool designed to under ream the hole while simultaneously drilling ahead, which is adopted from American Hughes Christensen Company. This technology is not only suitable in vertical well drilling, but also suitable for slim hole and big inclination well drilling. |
| |
The development of special application bit can be effective in complicated conditions.. CSC can produce special PDC bits as the customers' requirements: |
| |
As the drilling technology develops swiftly these years, AUTOTRACK、POWER-V and other rotary steerable tools have been widely used in the oilfield drilling. CSC can design and manufacture the rotary steerable PDC bit according to the specific demands of customers on the requirements of the varied kinds of rotary steerable tools. |
