Increasing the efficiency of jet pumps in drilling

Authors: Melnikov A.P., Panevnik A.V. (Ivano-Frankivsk National Technical University of Oil and Gas, Ukraine, Ivano-Frankivsk)

Key words: jet pump, ejector, head ratio, flow ratio.

The article considers the main purpose of jet pumps in the construction of oil and gas wells, namely, the increase in ROP. It is noted that the main drawback of the existing ejection systems associated with significant hydraulic losses in the working nozzle jet pump. On the basis of the analysis proposed device is designed for drilling wells, which reduces the load on the mud pumps in use, and also provides an opportunity to work with jetting bits.
