FIELD: oil and gas production.
SUBSTANCE: bi-stable oscillator influencing oil payout beds consists of working chamber, in one wall of which there is installed nozzle, while two outlet branches are connected at output. The working chamber corresponds to parallelepiped formed with side, upper and lower walls. The nozzle is replaceable and is installed coaxially to lengthwise axis of the working chamber in a front wall of the chamber. Also, axes of the outlet branches at the initial section form acute angle, while on outlet ends they are parallel. Length of an outlet end of the second branch exceeds length of the first one at value, facilitating delay in time of a pulse, which advances along the second branch at value, equal to period of duration of a pulse generated at output from the first branch in a working medium supplied to bottomhole of a well.
EFFECT: increased output of payout beds at increased distance between producers and pressure wells and raised general efficiency.
