Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to gas industry, particularly, to development of gas hydrate deposits. Method of producing natural gas from a gas hydrate deposit comprises constructing a well on a gas-permeable gas-hydrate formation, this formation is opened and a primary agent is periodically injected into the bottomehole formation zone, said primary agent being capable to decompose methane hydrates in thermobaric conditions of the formation, and then pumping into the bottomehole formation zone of a gaseous secondary agent containing carbon dioxide in an amount which enables formation of carbon dioxide gas hydrates in thermobaric conditions of the formation, and extraction of the produced gas is then carried out. Primary agent used is gas which does not contain carbon dioxide or has low content of carbon dioxide not more than 20 mol%, for example, nitrogen, or air, or flue gases, which simultaneously with decomposition of methane hydrates displacement of natural gas into the formation. Secondary agent used is, for example, nitrogen enriched with carbon dioxide or flue gas with carbon dioxide content of not less than 50 mol%. 
     EFFECT: invention increases recovery of gas due to exclusion of reduced permeability of bottomehole formation zone by water; increasing methane-containing gas extraction factor from formation.

Abstract: This relates to an apparatus for heat bonding a lid having a metallic layer to a plastic container. The container, filled with a product, is seated in a nest and a lid is seated in place thereon. There is at least one corner on the lid and projecting from that corner is a pull tab. An induction heating unit is associated with the lid and presses it tightly against the container while inducing electrical energy under controlled conditions into the metal layer. The induction heating unit is provided with a specific arrangement of ferrite members for controlling the induction of current into the metallic layer. The ferrite parts in conjunction with the induction coil serve to concentrate the induced electrical energy into substantial alignment with the induction coil notwithstanding the fact that there is a corner and there is projecting from the corner of the lid a pull tab.

Abstract: A method of producing self-supporting ceramic composite bodies of desired shaped by infiltrating a permeable preform with polycrystalline matrix material consisting essentially of an oxidation reaction product obtained by oxidation of a parent metal precursor, such as aluminum, and optionally containing therein metallic constituents. The composite body is formed by contacting a zone of a permeable preform, having at least one defined surface boundary spaced from said contacting zone, with a body of molten metal which is reacted with a suitable vapor-phase oxidant to form an oxidation reaction product. Within a certain temperature region, and optionally with one or more dopants in or on the parent metal or said permeable preform, molten parent metal migrates through previously formed oxidation reaction product into contact with the oxidant, causing the oxidation reaction product to grow into the preform toward said defined surface boundary so as to infiltrate the preform up to said defined surface boundary, and provide the composite structure of desired geometry.

Abstract: The technical sector of the invention is that of connecting devices between a projectile and a case. The device according to the invention comprises a ring (6) which has a front part (8) connected to the projectile by a first fastening means and a rear part (7) fixed to the case (2) by a second fastening means. The device is characterised in that the second fastening means is shaped in such a way that the action of the pressure of the combustion gases of the propellant charge exerted on the projectile (1) causes the separation of the latter, carrying the ring, and of the case, and in that the rear part (7) then comes into contact with an inner surface of the chamber (4) so as to ensure gastightness. The invention is used for ammunition of the backswept type fired from a smooth barrel. <IMAGE>

Abstract: This invention relates to drilling fluid additives that suppress clay swelling within a subterranean well and to methods for controlling clay swelling during the drilling of a subterranean well. Aliphatic polyamines and aliphatic acids react to form polyamides and polyamino acids that are water soluble, that have molecular weights of less than about 1000, and that have low toxicity levels. The polyamides and polyamino acids are added to water base drilling fluids which are circulated throughout a well. The drilling fluid additives and the method of controlling clay swelling provide for improved control of the rheological properties of drilling fluids along with an increased environmental compatibility.

Abstract: A method of effecting fluid movement in porous materials (e.g. metal reinforced concrete or porous geological media) by means of electroosmosis. The method comprises applying a sequence of voltage pulses between spaced apart electrodes (4, 5) having a region of porous material (1) therebetween. Each voltage pulse comprises a first portion in which an electroosmotically active first potential difference is applied between the electrodes (4, 5) to effect fluid movement in the region of porous material (1), and a second portion in which a second potential difference of opposite polarity is applied. In the case of metal reinforced concrete an additional voltage is applied to the metal reinforcement (2) in order to make the voltage of the metal reinforcement (2) negative with respect to the porous material (1) for at least part of the sequence of voltage pulses. The method is used for controlling humidity in metal reinforced concrete, treatment of water, irrigation, oil displacement in oil-/water-bearing strata.
