Definitions
- the utility model relates to the oil and gas industry and can be used in the development of oil and gas fields, and more specifically, to devices for reducing waterlogging of oil and gas wells.
- a device for reducing waterlogging of oil and gas wells containing a tubing (HKT), plugged from below, designed to be placed in the perforation of the casing, through holes are made in the lower part of the HKT, cut at the level of the lower casing perforation holes, and in the upper part of the HKT, above the casing perforation interval, an elastic flexible gas-oil-resistant cuff is secured that separates the space perforation from the rest of the casing with the possibility of isolating the oil-saturated formation from water / Declaration patent of Ukraine for utility model N ° 2546, IPC 7 E21B43 / 00, publ. 06/15/2004, Bull. W 6, 2004 /.
- HKTs are made, as a rule, of steel, and if it is necessary to remove such a pipe from a well of kilometer depth, this technological task turns out to be extremely difficult in many cases. It sometimes takes months to solve such a problem, which significantly reduces well productivity.
- the proposed utility model is based on the task of creating such a design in which HKT, if necessary, could be easily destroyed and removed from the well.
- the problem is solved in the proposed device, which, as well as the known device for reducing water cut in oil and gas wells, it contains a tubing (HKT), which is plugged below, designed to be placed in the lower part of the casing string, through holes are made in the lower part of the HKT to enter the fluid cavity HKT, and an elastic flexible gas-oil-resistant cuff fixed in the upper part of the HKT above the through holes of the perforation and designed to separate the volume of HKT with through holes from the volume of the casing, installed , with insulation oil saturated reservoir from the water, and, according to the proposal, HKT benzomaslostojkie legkorazburivaemogo made of non-metallic material, and its lower end is filled with cargo to secure the position of the lower end and prevent it from floating up.
- HKT tubing
- HKT tubing
- inexpensive polymeric materials can be used, for example, based on polyethylene (see ((Polyethylene pipes. GOST 18599-2001 “and” Polyethylene pipes. GOST 18599-2001 “), fiberglass or fiberglass, which are easily destroyed by the action of a drilling tool, do not affect the state of the environment and do not dissolve in the well.
- HKT stiffness and cost of a running meter of the pipe are taken into account.
- the most rigid of these is a fiberglass pipe, but its cost does not always suit operators, so in most cases they use HKT made of a material based on polyethylene.
- the cargo with which the lower end of the HKT is filled lead (for example, from waste car batteries), concrete, and other improvised ceramic materials can be used.
- the weight of this cargo is 5-8 kg.
- HKT 2 is installed in the casing 1 of the well.
- the HKT 2 casing is made of pipes of the SDR 11 grade.
- the main raw material for the production of the pipe is polyethylene.
- Pipe manufacturer - “Ukrainian Polymer Engineering”, Ukraine.
- the pipe is made in accordance with the Technical conditions of DSTU BV.2.7-73-98 /.
- a fishing head is mounted on top of the HKT 2 for raising and lowering the HKT 2 (not shown), below which a cuff 3 is attached to the HKT 2, which separates the perforation zone 4 of the casing 1 from its upper part.
- the cuff 3 is made of an elastic elastic gas-oil-resistant material - gas-oil-resistant rubberized fabric.
- the preliminary seal of the cuff 3 provides a gasket made of an elastic petrol-oil-resistant fabric / not shown /.
- the bottom of the HKT 2 is plugged and filled with a load of 5 - lead.
- the bottom end of HKT 2 rests on the bottom of the borehole 7 (bottom of the sump).
- the lower part of the HKT 2 is made of perforated holes 8, intended for the entry through them of the product from the oil-saturated zone 9 of the reservoir.
- the holes 8 are located at the level of the zone of the lower holes 4 of the casing 1.
- the cuff 3 is installed above the perforation zone 4 of the casing 1 above the oil-saturated zone 9 of the reservoir and separates this zone from the rest of the 11 casing 1 of the well. Deeper than the oil saturated zone 9 of the formation is the water saturated zone 12 of the formation.
- the proposed device works like this.
- the flow of oil and produced water when leaving the formation changes its direction, going from top to bottom to the holes 8 on HKT 2 and rises through it into the space 11 of the casing 1 above the cuff 3 of the device.
- the cuff 3 is completely compressed in the casing 1 due to the deposition of solid mechanical layers on it from above impurities that are deposited from the formation material when the well stops and due to changes in the fluid velocity above the cuff 3.
- the height of the sealing layer on the cuff is determined by the distance from the cuff flange 3 to the upper end of the fishing head.
- the remaining mechanical impurities are carried out with the production of the well up to the collecting manifold (not shown).
- the HKT 2 Due to the weighting of the end face of the HKT with a load of 5, the HKT 2 is fixed at the bottom 6 of the sump. Oil, penetrating the pores of the water-saturated zone 12 of the reservoir, reduces the yield of water in the bottomhole formation zone. Thus, an oil and gas shutter is created, which prevents the penetration of water into the oil-saturated zone 9 of the formation (even when the well stops working) and helps to increase the oil content in the well production. If it is necessary to replace HKT 2, a drilling tool is introduced into the casing 1, which easily destroys the HKT, and its fragments (waste) are washed out with water.

Abstract
L'invention se rapporte au domaine de l'industrie pétrolière et gazière et peut s'utiliser dans l'exploitation de gisements de pétrole et de gaz et plus particulièrement dans des dispositifs pour réduire le mouillage de la production de puits de pétrole et de gaz. Le dispositif de l'invention comprend un tube à pompe et compresseur (TPC) obturé par le bas, destiné à être disposé dans une cavité de colonne de tubage, et des orifices transversaux sont réalisés dans le bas de la colonne TPC pour amener un liquide dans la cavité du TPC, et un manchon élastique souple résistant à l'huile et à l'essence, fixé dans la partie supérieure du TPC en dessus des orifices transversaux de la colonne de tubage et destiné à séparer le volume du TPC des orifices transversaux du volume de la colonne de tubage, et monté de manière à permettre l'isolation de la couche saturée de pétrole par rapport à l'eau. Selon l'invention, le TPC est fabriqué d'un matériau résistant à l'huile et à l'essence et facile à forer, et son extrémité inférieure est remplie d'une charge destinée à fixer la position de l'extrémité inférieure et à empêcher son immersion. On utilise en tant que matériau résistant à l'huile et à l'essence et facile à forer pour fabriquer le TPC des matériaux polymères peu coûteux, par exemple, à base de polyéthylène, de stratifiés fibre-résine ou de stratifiés tissu-verre qui se désagrègent rapidement sous l'action d'un trépan de forage, ne nuisent pas à l'environnement et sont facilement évacuables des puits. Le modèle d'utilité de l'invention vise une structure qui permet de détruire facilement le TPC et l'évacuer du puits.
