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.

国际分类 B65G 69/20 申请号 PCT/UA2003/000010 申请人 BARTENEV, Oleksandr Volodymyrovytch 发明人 BARTENEV, Oleksandr Volodymyrovytch

Field of the invention: warming-up and subsequent tank unloading from hardened viscous material, mainly viscous oil and mineral oil products during the cold seasons of year. The essence of the invention: In the method steam is submitted in through nozzles of submersible heater, before warming-up actual temperature of the hardened material is measuring, and its warming-up is carried out in two stages divided among themselves by a technological pause at which steam submission is absent, at the first stage of warming-up a gain of temperature of the hardened material is provided, and duration of said technological pause is determined depending on results of measurement of variable depth of a mirror of a bath of rests of loaded material, and also from results of measurement of variable height of nozzles arrangement of said submersible heater concerning said mirror of a bath of rests of loaded material, breaking said technological pause in steam submission at negative result of values of measurements difference of depth of said mirror of a bath of rests of loaded material and height of an arrangement of said nozzles of said submersible heater concerning this mirror. In the device for warming-up a viscous material in the tank, mainly oil and mineral oil, comprising the first independent duct for submission of heat-carrier, pneumatically connected with jet devices directed in parallel to a mirror of said material in the tank and executed as hollow vertical bar, the second independent duct for submission of the heat-carrier, located in parallel to said first independent duct and near to it and pneumatically connected with face nozzles directed to a bottom of the tank , and also means for overlapping of the heat-carrier submission.

8.WO/2002/048498ENHANCED OIL RECOVERY METHOD USING DOWNHOLE GAS

WO - 20.06.2002

国际分类 E21B 41/00 申请号 PCT/AZ2000/000001 申请人 WHITEHALL INTERNATIONAL TRADERS (GB) 发明人 KUSHNIROV, Valeriy

The invention relates to the recovery of liquid or gaseous fluid media from wells, more specifically to methods for recovering residual nonrecoverable oil from depleted formations by a secondary pressure and the gasification thereof. The inventive method consists in naturally transferring compressed gas from lower gas-bearing beds to upper depleted oil-bearing stratums and creating a determined relation between gas and petroleum hydrocarbons. Said relation allows the residual non-recoverable oil in the stratum to be dissolved and afterwards recovered in the operational mode of the natural depletion of oil-and-gas condensate pools.
