An apparatus for generating signals and energy for transmission to a large mass (17). The apparatus incorporates a pulsed generator (10) such as a compensated pulsed alternator for storing and for discharging large amounts of energy in a controlled manner for transmission through a vibrator or similar electromechanical device.

10.WO/2000/022280ACOUSTIC METHOD (ARWL) FOR APPLYING AN ACTION ON A WELL AND ON THE LAYER OF A FIELD OF MINERAL RESOURCES

WO - 20.04.2000

Класс МПК E21B 28/00 № заявки PCT/RU1999/000367 Заявитель ORENTLIKHERMAN, Isaak Aronovich Изобретатель ORENTLIKHERMAN, Isaak Aronovich

The present invention pertains to the extraction of mineral resources obtained by a method involving the use of wells, and essentially relates to an acoustic method for applying an action on a well and on the layer of a field of mineral resources (ARWL). This invention can be used in the crude-oil extraction as well as in the gas, mining and geological prospecting industry. This invention is more particularly intended for use in the gas and crude-oil extraction techniques, mainly during operations for the rehabilitation of wells and layers (acoustic rehabilitation of wells and layers or ARWL) in order to increase the crude oil yield from the layers and to enhance the crude oil extraction. The method of the present invention comprises operations that involve applying a complex acoustic action on the perforated zones of the well and carrying out a selective treatment of the perforation interval and of the producing strata of the layer using a directed acoustic field in order to combine the pressure, the duration and the range of the action. The method involves using sound and ultrasonic signals with directivity characteristics of up to 180° as well as acoustic pressure indicators from minimal values necessary for modifying the current operation of the well to maximal values defined by the elasticity limits of the rock. These operations are carried out for a duration which represents an efficient action duration, the action range being the initial efficient action range. The treatment can be made according to a basic mode that involves sequentially treating the well perforation interval and the producing strata of the layer using three acoustic signals, or according to another combined sequence determined from the type and the condition of the well. This method is used for unifying the complex action for all types of wells having different exploitation modes and being operational or not.
