FIELD: process engineering.
SUBSTANCE: invention relates to oil production, particularly, to devices for excitation of wells. Cable hydraulic vibrator comprises case with coil to be connected to logging cable by two working elements. Note here that every working element is composed by piston from magnetic material. Compression spring is arranged between the pistons. Case is equipped with extra coil, chamber to accommodate said working elements and bores made at case ends and in the area of said spring. Note also that every working element is accommodated inside said coil.
EFFECT: higher efficiency and reliability.
