Reasons for the high demand for tungsten carbide nozzles within the petrochemical industry
Tungsten carbide is an unmatched material when it comes to usage in the Oil and Gas industries. These industries often have extreme conditions both onshore as well as offshore. Various abrasive liquids, solids, sand along with high temperature and pressure conditions cause a significant amount of wear in all steps of the downstream as well as upstream processes. Parts like valves, choke beans, valve seat, sleeves and nozzles made out of the strong and highly resistant tungsten carbide are hence high in demand. Owing to the same, the demand and usage of tungsten carbide nozzles for the oil industry along with other important products have surged in the last few decades.
What makes tungsten carbide a great choice for nozzles?
• Super coarse grain hard alloy virgin raw material , 100% alloy by pressing and sintering , so that the hardness and toughness of the drill bit are increased by 30% simultaneously .
• Unique design, Drilling and digging speed raise 20%, life span extend 30%
• Dimensional stability in environments with high temperature and pressure conditions
• A fine finish which makes them easy to clean
• Great wear resistance, abrasion resistance
• Cost effective owing to long life span and negligible maintenance needs
How’s the ultra-high pressure nozzle plays an important role in the design of ultra-high pressure bit and gain best effects.
At present, the number of deep well ultra-deep well drilling in the world is gradually increasing. Due to the increase of well depth, the drilling speed is significantly reduced, and the drilling cost of a deep well is less than tens of millions, more than hundreds of millions of yuan, the problem of huge deep well drilling cost will become increasingly prominent.Increasing drilling rate and reducing drilling cost have become a hot and difficult problem for drilling engineering experts in recent years.However, in the current rotary drilling mode, only 5% ~ 20% of mechanical energy is used for rock breaking due to low energy transfer efficiency, which makes the rate of rock-breaking drilling difficult to be satisfactory.Therefore, it is necessary to give full and reasonable play to the potential of existing technologies and mechanical equipment, make full use of hydraulic energy, and improve the rock-breaking and rock-clearing capacity of jet flow at the bottom of well, so as to achieve the purpose of increasing drilling speed and reducing cost.Drilling engineering experts all over the world agree that it is a fundamental way to solve the problem of ultra-deep well drilling speed by using downhole supercharger to implement ultra-high pressure fine jet assisted mechanical rock-breaking drilling, namely ultra-high pressure jet assisted drilling technology.Field experiments conducted by Veenhuizen et al. with uhp downhole pumps show that, for shale, uhp jet assisted rock breaking speed is about 1.45 times that of conventional rock breaking speed, 1.50 times that of granite, and up to 2.0 times that of sandstone.Therefore, it is of great significance to the development of ultra-high pressure drill, which is a direct breaking tool.The placement of ultra-high pressure nozzles plays an important role in the design of ultra-high pressure bit.
*Most Significant Factor(1) under certain conditions, such as nozzle diameter, injection Angle and spray distance, the higher the jet pressure is, the better the rock-breaking effect will be;
