WELL ELASTIC WAVE SOURCE

摘要

The invention relates to methods for exploration geophysics in the oil-gas industry. The inventive well elastic wave source consists of a well shell comprising an energy storage, a charging unit, an electric hydro-pulse discharging unit provided with two electrodes and a unit for supplying a metal wire to an interelectrode space. Said unit for supplying a metal wire comprises a wire storing drum, a wire pulling mechanism which is embodied in the form of two spring-loaded rectangular plates which are arranged on the opposite ends of a rod and whose pointed ends contact the wire at an angle which makes it possible to catch and transport said wire towards the interelectrode space. The reciprocating-rotational motion of said rod is carried out by an axis and drawbar connected to the solenoid armature. The wire is displaced two times during one rotation of the rod with the aid of the alternate catching thereof by one of the plates. The solenoid and the drawbar connected to the armature thereof are arranged on the one side of a dielectric plate, the wire storage drum, two spring-loaded rectangular plates, a wire guiding surface area and the rod being arranged on the other side thereof. Said rod and the drawbar connected to the solenoid armature are connected to each other by an axis passing through a hole in the dielectric plate.
