Geological Spherical Core Drilling Bits With Large Alloy B22

Quality Spherical Drill Bits Made In China With Large Alloy B22 Drill Pipe For Core Drilling

Product introduction: PDC bit is very common in the oil drilling industry, which is a necessary tool for drilling and mining, and also the abbreviation of poly crystalline diamond composite bit.

PDC bit also known as poly crystalline diamond composite bit, has been widely used in the oil and gas drilling industry and directional well construction. It has the advantages of long working life and low down hole accident rate.

1,PDC drill bit Size: 3 5/8 inch -17 1/2 inch

2, PDC BIT The material of the drill body is divided into: steel body and carcass. The steel body is cheap to build and the carcass is resistant to friction.

3,PDC BIT Drill blade: 3.4.5.6.7.8 knife

4,PDC BIT Diameter of composite sheet: 13mm. 16mm .19mm

5, PDC BIT According to the drill body material classification

1)PDC drill bit Metrix body PDC bit: Fetal diamond composite bit is a cutting bit, it is the diamond composite piece by brazing welded to the drill body. The tire bit is sintered by tungsten carbide powder, and the tire body is brazed by synthetic polycrystalline diamond composite sheet, and the diameter is maintained by diamond (drilling and production equipment experts).

2) PDC drill bit Steel type PDC bit: steel body PDC bit, using nickel-chromium molybdenum alloy machining forming. After heat treatment, drilling in the body of the drill, the artificial poly crystalline diamond composite sheet is pressed into the (compact) drill bit, tungsten carbide diameter is columnar.

6, PDC bit Main uses: Geological exploration with composite sheet drill: mainly used for geological exploration work, suitable for soft to medium hard rock, has developed a new type of composite sheet manufacturers, can be used for ten hardness rock. Coal field drilling with composite sheet bit: mainly used in coal mining on the coal seam drilling. Generally speaking, the rock formation of the coal field is soft, and a large number of composite sheet bits are used, such as anchor bit, three-wing bit and so on. Compound sheet drill for oil exploration: mainly used in oil and gas fields of drilling tools. At present, the composite chip bit used in the oil field has high cost and high requirements in all the composite chip bits.

Product advantage: With the continuous iteration of product performance, the quality of this kind of drill has also been improved a lot, not only impact resistance, corrosion resistance, wear resistance, have been greatly improved these, but also because the manufacturing process has been a great change in the mixing process, the quality is getting better and better. In the production process of the product cutting, teeth have also been improved, not only higher toughness and heat, stability is better, in the long-term use can also maintain stability, maintain durability. The development of PDC bit technology and materials has not only achieved a breakthrough, but also undergone great changes in the use of occasions, not only corrosive bottom or hard bottom can be used, after all, the original product may be due to the low quality of the product, so in the relatively hard sandwich can not be used easily damaged, such as its technology has been improved, In the hard rock formation can also be used, and more and more recognized by people, now in the purchase of PDC bits can understand the products produced by relevant enterprises, choose professional manufacturers of product quality is more reliable, the quality of
