background
As China expands its exploration of oceans, especially deep-sea oil fields and oil and gas basins, petroleum equipment manufacturers face more stringent requirements: 1. The processed materials are turned from alloy steels to high-chromium and high-nickel heat-resistant and corrosion-resistant alloys; The high sealing and high reliability requirements of the parts design must have high processing precision and durability. 3. The strict delivery time requires the supplier's logistics chain to have high reliability and rapid response capability.
The oil and gas industry has a wide variety of parts, but if classified, it can be divided into three parts: drilling, production and control tools. The three types of parts are representative: 1. Drilling field: oil drill bit; Production area: OCTG; 3. Control tool field: tools such as control, pressure pump, valve and completion equipment.
First, the field of drilling
With the advancement of domestic material technology and welding technology, new drill bits have begun to be used in deep well drilling. However, due to manufacturing technology, production efficiency and cost have always been a stumbling block to the development of domestic drill enterprises.
For example, the hardness of the journal of the roller bit part is about HRC60. Due to the structural design requirements, the part is also welded with wear-resistant material, which is accompanied by a large interrupted cutting, which makes a great deal for the processing of the product. The challenge. Seco's CBN products have different materials to meet the challenges of difficult machining. CBN060K is designed for the extremely interrupted cutting of hardened steel. CBN160C provides extremely high stability and predictable life. CBN170 is specially designed for nickel-based superalloys. Efficient processing of processed materials. In response to the thread turning of the roller bite after welding, Seco Tools offers a high toughness material CP500 for the complete range of oil and gas thread products.
Diamond drill bits are generally processed directly from forged blanks. There are a large number of metals to be removed. High life requirements and high efficiency requirements. The fast feed milling cutters below are good choices. They can provide a depth of cut of 2.5mm and a tooth depth. Gives the highest efficiency of 3.0mm/r, as well as the material of dry and wet cut blades. The surface accuracy required by the customer is usually achieved in one process. Because the blade has a small main deflection angle and the cutting force is concentrated in the axial direction, it is very suitable for such contour milling with large overhang.
