The Characteristics of PDC Matrix Body Bits
PDC matrix body bits are drilling tools widely used in oil and gas wells, coal mines, and geological exploration. Their high hardness, high strength, long life, and excellent rock-breaking efficiency make them important tools in the drilling field. Their material and structural design allows them to perform exceptionally well in soft to medium-hard formations, while also possessing good erosion resistance and wear resistance. They are suitable for drilling operations under various complex formation conditions. Their comprehensive characteristics are mainly reflected in the following aspects:
Material and Structural Characteristics:
The matrix part of the PDC matrix body bit is usually made using a tungsten carbide powder metallurgy sintering process, which has high hardness, high strength, and good wear resistance, while also having excellent impact resistance. High-entropy alloys or tungsten carbide powder are often added to the matrix material to form a uniformly distributed eutectic structure to improve the overall performance of the matrix. In addition, the PDC cutters welding strength of the matrix body bit is high, usually exceeding 35 kN/mm², effectively withstanding various stresses during the drilling process.
Applicable Formation Range:
PDC matrix body bits are suitable for soft to medium-hard formations, and perform particularly well in medium-hard to hard formations. Their design allows for rapid drilling under different formation conditions, especially suitable for long-distance main hole drilling. In addition, matrix body bits can also adapt to some hard and brittle interbedded formations.
Rock Breaking Efficiency and Cutting Performance:
PDC matrix body bits achieve rock shearing and breaking through polycrystalline diamond composite cutters (PDC), with high rock-breaking efficiency. Their cutting tooth design optimizes tooth shape, rake angle, and tooth density, improving mechanical drilling speed and drilling efficiency. In addition, the matrix body bit has various PDC cutters combinations, and the appropriate cutting tooth type can be selected according to the formation characteristics, such as scraper type, single tooth type, and combination type.
Service Life and Maintenance:
PDC matrix body bits have a long service life, typically reaching hundreds or even thousands of meters. Their manufacturing process is simple, the production cycle is short, and worn parts are easy to replace after repair, thus extending the service life. In practical applications, matrix body bits exhibit good erosion resistance and wear resistance, and maintain a long life even under high flow rate conditions.
Hydraulic Design and Cleaning Capacity:
PDC matrix body bits use a hydraulically balanced design, equipped with replaceable threaded nozzles, which can form an ideal bottom hole flow field, fully cleaning and cooling the cutting teeth. This design not only improves the service life of the cutting teeth, but also enhances drilling efficiency.
Manufacturing Process and Cost Effectiveness:
The manufacturing process of PDC matrix body bits includes mold design, matrix formulation, powder molding, and sintering. The manufacturing cost is relatively high, but the performance is superior, especially in complex formations, outperforming steel bits. In addition, the production cycle of matrix body bits is short, suitable for mass production.
