SU37633A1 - Device for pneumatic lifting of oil and others from boreholes - Google Patents

Description

When drilling in oil areas, it is often necessary to encounter the fact that the pressure inside the well is not good enough to force oil onto the surface of the earth. In these cases, either the oil is pumped out directly from the surface, or air or another gas is injected into the well, or finally, the pressure medium is injected into the oil column that has risen in the well due to e: natural pressure, causing the oil column to rise to the surface .

Mechanical pumps are the disadvantage that they require very frequent replacement of parts and repairs, as the flowing mineral contains, in addition to oil, paskov and small stones, which damage the pumps. An ordinary air ram, also used for lifting oil, does not work very economically and often damages the well in areas where the natural pressure is very low. The latter drawback is eliminated by the fact that the effect of air on the well is adjusted accordingly to the change in the height of the oil level in the well. Cost-effective operation is achieved by the fact that the application of the pressure medium is automatically stopped, or at least

(655)

It is limited and occurs only at those times when a sufficient amount of oil has accumulated near the drill pipe in order to make it profitable.

According to the invention, the air or other pressure medium is automatically supplied to the fluid at the bottom of the well only at times when a sufficiently large amount of fluid has accumulated there and, due to the shear, causes it to go into the pipe leading to the oil pipeline or to the storage tank. In this way, the diminutive environment is spent sparingly. The medium is controlled by valves, the movement of which, in turn, depends on the change in the oil level in the skirt.

The drawing shows a schematic sectional view of a device for pneumatic lifting of oil, etc., from drilling drills, all parts being shown in the position that they occupy when the injection pipe does not force out the oil.

PATENT FOR INVENTION fire extinguishing bomb.

To the patent of the in-tsa Erwin Puchner (Erwin Puchner), in the city of Wetzelsdorf near Graz, Austria, December 2, 1932 (refer to the first.

On granting a patent published June 30, 1934. The patent is valid for 15 years dated June 30, 1934.

It is known to extinguish fires using various extinguishing powders or masses, which are scattered or otherwise distributed on the surface of burning objects, and the fire is extinguished partly because of the formation of dust and, partly, during the formation of foam, or due to the formation of gases, flame is extinguished or the possibility of its spreading is eliminated. However, bringing these extinguishing agents to a fire center is very difficult and dangerous, or even impossible.

It has already been proposed to place said extinguishing powders in readily destructible tanks and insert an explosive charge inside the powder, into which the ignition cord protruding from the tank is immersed. Such extinguishing bombs can either be located in a space threatened by a fire, or in the event of a fire these bombs can be thrown into flames. The extinguishing effect is achieved in such a way that the protruding cord ignites from a fire and causes an explosion of charge, with the result that the quenching powder must be scattered. This also means

use a sudden increase in air pressure caused by an explosion to extinguish.

All known extinguishing bombings, however, have serious flaws, which in many cases make their use impossible or dangerous. First of all, charge ignition was carried out from the cord with insufficient reliability and often too late, when the fire was already too widespread, besides the tanks, which are mostly made of folders, should be with relatively strong walls so that when dropped, they sprawled; This caused the use of a strong explosive charge, so that the quenching powder could well turn around in an explosion. In view of the strong charge, working with such bombs turned out to be dangerous, and one could also expect significant damage during an explosion. The object of the present invention is such an extinguishing bomb, the design of which provides a quick and reliable ignition of the charge instantly after being hit by a fire, what is the design, moreover, so strong that not only by hand, but also with the help of a throwing device.

it is possible to throw a bomb into the fire without fear that it will burst when falling, and at the same time a charge so small that it is sufficient only to scatter the extinguishing powder.

For this purpose, in the proposed bomb, the charge is arranged in a tubular vessel made of celluloid or from other highly flammable material, which is supplied with several appendages protruding to the outside to facilitate the burning. The extinguishing agent is in an annular vessel made of paper or other combustible material, and the inner annular walls of this reservoir are adjacent to the hollow tubular body of celluloid or the like, so that the walls of the reservoir ignite or burn when ignited. extinguishing agent. A rod extends through the tubular hollow body, which carries two metal cups of a multi-faceted shape, having on the outer surface of the trough, into which convex sheets of cardboard or the like are inserted, with tension, and under pressure from the inside these sheets open outwards, so that charge for spraying extinguishing agent.

The boom can be mounted on a stick that provides the possibility of throwing out an extinguishing bomb by hand or with a spring or similar device.

In FIG. 1 is a side view of a fire extinguishing bomb; FIG. 2 - the same, top view; FIG. 3 is a section along the line CD in FIG. 2; FIG. 4-section along the line. E-R in FIG. 3

In the proposed fire extinguishing bomb on a stick or on a metal pipe 7, the tongs 5, which are inside the bomb with core 4, are reinforced. The last at the end is equipped with a thread 5, on which you can screw the nut b. The pliers 3 are reinforced with the aid of the recess 2 on the stick 7, so that they remain together even when thrown by hand.

An aluminum cup 8 is mounted on the core 4, which is provided with a chola on the outer edges and for quick heat removal, part of the core 4 is surrounded by a sleeve 9. The front end of the bomb is closed by a cover cup 7, which is pressed by means of a nut 6- wick part made up of two shells // and 12; the wick concentrically surrounds the core 4 and the sleeve R. The wick is made of a highly flammable material, such as celluloid, and in the middle has a chamber 15 where the powder is introduced. The wick can also have appendages 14 passing through the slots of 13 cups of p 8, which ensures rapid ignition at the fire site. A circular vessel 16 is placed around the wick, for example, from paper or from another material that does not suffer from a composition that is an extinguishing powder, for example, sodium carbonate or a liquid, for example carbon tetrachloride. This vessel 16 is protected by free sheets 10 from a folder or the like from damage. The sheets 10 are clamped in the grooves of the cups 7 and 5, and a sealing ring 18 is still placed on top of them.

When a bomb is thrown into a fire, a wick is ignited from contact of appendages 14 with fire, or as a result of heat transferred from metal cups 7 and 5. This produces an explosion of powder in chamber 15, and simultaneously or somewhat, charring of the inner annular walls of the vessel 16 is obtained. to the wick //, 12. The vessel 16 is completely destroyed by the explosion, and the sheets 10, when tearing the gluing ring 18, are pushed out, so that their edges come out of the troughs of the cups 7 and. The tire formed by the sheets 10 is thus completely destroyed, and the extinguishing agent 17, not meeting any resistance, is scattered.

The subject of the patent.

1. A fire extinguishing bomb, consisting of a body that is easily destroyed by the explosion of a powder charge, is enclosed in it through the transfer of a flammable material, using a powder-like extinguishing agent laid into the body around
