FIELD: soil or rock drilling; mining.
SUBSTANCE: group of inventions relates to tubular elements with nozzle for control of well fluid. Tubular element of borehole includes main pipe containing wall, slot in wall, providing passage between internal diameter of main pipe and outer surface of main pipe, nozzle in slot, containing mouth, diffuser tube on outer surface, receiving fluid, coming from mouth. Diffuser tube comprises inlet channel opening into inner diameter confined by wall of diffuser tube, wall dissipating fluid at bend in diffuser tube, and multiple outlet channels from diffuser tube.
EFFECT: technical result is improved tubular elements with nozzles.
