2.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

Clasificación Internacional E21B 28/00 Nº de solicitud PCT/RU1999/000367 Solicitante ORENTLIKHERMAN, Isaak Aronovich Inventor/a 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.

4.WO/2000/020896PIEZOELECTRIC CONVERTER

WO - 13.04.2000

Clasificación Internacional B06B 1/06 Nº de solicitud PCT/RU1999/000361 Solicitante ORENTLIKHERMAN, Isaak Aronovich Inventor/a ORENTLIKHERMAN, Isaak Aronovich

The present invention pertains to the field of geophysical well equipment and of equipment for applying physical actions on the fields. This invention can be used in geological prospecting, in the mining, petroleum- and gas-extraction industry as well as in other industrial branches for intensifying the extraction of mining resources. The piezoelectric converter includes a piezoelectric packet that comprises longitudinally polarised piezo-ceramic rings which are connected in parallel and associated with end parts having a thickness of λ\40, wherein λ is the wavelength of the material used for said parts. The piezoelectric converter also includes a reinforcement rod member as well as a retaining ring member that provides the longitudinal compression forces of the piezoelectric converter, i.e. the reinforcement force thereof. The retaining member comprises a flute for dampening oscillations and for eliminating the need for any reinforcement tube in the oscillating system. The piezoelectric packets are connected by a flexible insert or resilient member. The rod member and the retaining member are connected so that the reinforcement force can be adjusted. The resilient member and the end parts are made of a material exhibiting wave resistance as well as a thermal expansion coefficient for the ceramic of the rings, e.g. titanium or steel. This piezoelectric converter has an increased reliability and an extended life time.
