FIELD: oil and gas industry.
SUBSTANCE: bottomhole drilling fluid flow rate sensor includes a housing, a diaphragm and connecting tubes. At that, the device located in lower part of a drill pipe immediately above a bit and rigidly fixed on the pipe walls has a mechanical oscillating system made in the form of a hollow counterweight with a membrane, which is torsionally suspended on two capillaries, and with a constant magnet fixed on it, a system of actuation and pickup of oscillations, which interacts with a constant magnet field, and two separating vessels interconnected with the capillaries. Fluorocarbon liquid "Б"-1 serves as separating liquid for space under the membrane of the counterweight, and dibutyl phthalate - for space above the membrane.
EFFECT: improving reliability of measurement of the drilling fluid flow rate immediately during well drilling process.
