The Most Significant Factor of Tungsten Carbide Nozzle

Tungsten carbide is an unequalled material when it comes to usage in the Oil and Gas industries. These industries frequently have extreme conditions both onshore as well as offshore. Various grinding 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 seats, sleeves and nozzles made out of the strong and highly Tungsten carbide nozzles are hence high in demand. Owing to the same, the demand and usage of tungsten carbide nozzles for the oil industry along with other main products have surged in the last few decades.

At present, the number of deep well ultra-deep well drilling in the world is slowly increasing. Due to the increase of well depth, the drilling speed is notably 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 important.Increasing drilling rate and reducing drilling cost have become a hot and hard problem for drilling engineering experts in recent years.

*Most Significant Factor of Tungsten Carbide Nozzle is

(1) Under certain orders  such as nozzle diameter, injection Angle and spray distance, the higher the jet pressure is, the better the rock-breaking effect will be.

(2)Under the condition that nozzle diameter, injection Angle and nozzle speed in are constant, the optimal spray distance increases with the increase of pressure, reaching 32.5 times of nozzle diameter at 200MPa;

(3) The essence of the nozzle moving speed is to reflect the action time of jet erosion rock. When it is less than 2.9mm/s, it has little impact on the erosion effect of rock.

(4) When the pressure is lower than 150MPa, the jet pressure increases and the rock-breaking volume per unit power increases speadly; however, when the pressure increases further, the rock-breaking volume per unit power decreases slightly, and the rock-breaking efficiency is the highest at 150MPa.

(5) Ultra-high pressure nozzle moves in forward mode, with the most rock-breaking effect and the best injection Angle of 12.50.
