Near Dril Bit Ejector Unit

It is generally known that rate of penetration (rop) is one of main factors having an influence on cost-performance characteristics of drilling. The near bit ejector unit (nbeu) is an efficient device for drilling rate increases. It can improve the bottomhole flow field and make full use of hydraulic power to crack the formation. It can be used on rotary drilling, on drilling with pdm and on turbine motor drilling. It is an anti-balling device. We can guarantee that by fulfillment of our technology you can increase the rate of penetration (rop) and bit footage from 40% and more. These factors help reduce the timetable, capital and power inputs.
advantages of nbeu:
1. the rate of penetration (rop) is increased
2. drilling time is decreased
3. saving of bits quantity and trips for bit’s replacement
4. bits status: suitable for further use.
