Carbide Nozzles For Oil Drilling

Product Description

In the oil drilling industry, high-pressure abrasive jet technology is often used to exploit deep oil reservoirs and marginal oil reservoirs. Since the high-pressure abrasive jet is based on the high-pressure water jet, a certain amount of abrasive particles is added, which greatly increases the impact of the jet, and also increases the cutting speed of the rock formation to a certain extent. This is the most widely used high-pressure jet in oil drilling technology. Under normal circumstances, oil drilling is generally in an environment of high confining pressure, so the nozzle has to bear the impact of high-speed abrasives during the working process, which makes the wear condition serious, the service life is low, and the drilling efficiency is also affected. The emergence of Carbide Nozzles for Oil Drillin has improved this situation to a certain extent. The hardness and high enough fracture toughness of the material have improved the erosion and wear resistance of the nozzle. In addition, the appropriate WC grain size in the WC-Co cemented carbide nozzle can further increase the hardness without reducing the toughness of the material, thereby further increasing the service life of the nozzle.

Cemented carbide has high hardness, strength, wear resistance and corrosion resistance, known as "industrial teeth", used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts, widely used in military industry, aerospace , mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, with the development of downstream industries, the market demand for cemented carbide continues to increase. And in the future, the manufacturing of high-tech weapons and equipment, the advancement of cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for cemented carbide products with high-tech content and high-quality stability.

The manufacturing process of Carbide Nozzles for Oil Drillin is much more complicated than that of metal nozzles, and the cost is relatively high, but the service life is longer, which is longer than that of metal nozzles under the same use conditions. Cemented carbide materials have high strength and toughness, good thermal conductivity, and their hardness and heat resistance are higher than metal materials; the erosion and wear rate of cemented carbide nozzles is much smaller than that of metal nozzles, and their erosion resistance is high. on metal nozzles. However, cemented carbide has high hardness, low toughness, and poor processing technology, so it is not suitable for making nozzles with complex structures. In practical applications, the hardness alloy is usually made into a ring or block and embedded in some severely worn parts of the nozzle. A small part is used for casting. For example, the y-type nozzles used in the United States, Canada and other countries and the multi-stage nozzles in my country are inlaid with carbide in the vulnerable parts of the nozzles. The most commonly used fan-shaped nozzles and cone-shaped nozzles use stainless steel nozzle bodies to inlay tungsten carbide nozzles.

Generally, in the case of high liquid pressure, cemented carbide is used to resist the wear of high pressure on the nozzle, so as to improve the service life of the nozzle and the best effect of industrial effect. This type is mainly fan-shaped cleaning nozzle. In the case of super corrosion or wear in the environmental protection industry, a suitable alloy (C276) is used to maintain the normal operation of the industry. The former belongs to machining and manufacturing, while the latter belongs to mold production. One has high requirements on the production process, and the other has higher requirements on the accuracy of the material.
