SU27009A1 - Device for extinguishing oil well fires by pumping liquids and gases that do not support combustion into the well - Google Patents

Description

The present invention relates to a device for extinguishing fires in oil wells using a previously known method of extinguishing with gases and liquids that do not sustain combustion, which gases and liquids flow from the fire base through pipelines into the covers worn on the top of a casing of burning oil. the fountain, after blasting safety glass caps, closing the holes in the casing for the inlet of gas and liquid during normal operation of the fountain.

FIG. 1 of the schematic drawing shows a longitudinal section of a fire extinguishing device for oil wells; FIG. 2 shows a section along the line LM in FIG. one; FIG. 3 is a section along the line BUT in FIG. one; FIG. 4-modified fire extinguishing device in longitudinal section; FIG. 5-section along the line / Y / in FIG. four; FIG. 6 glass cap in longitudinal section.

Two metal covers are attached to the upper part of the casing pipe g, in any way, one case is a-below ground level and the second b-above ground level.

The casing pipe, enclosed in the bottom case, has around its circumference several openings 1, into which three removable case inside and a special glass caps 2 are screwed on, destroyed by an explosion of gunpowder I charge with an electric explosion, laid in the pipeline for protection and. connected to the inductor located on the fire base of the fishery I. In the upper case, there are no holes in the inside of the casing but there are holes 4, 5, 4 and 5 on the side outside the case. 5.

Both covers a and b are connected by pipelines with stationary gas, I foam or snow devices, as well as with the water supply j located at the central fire protection base of the fishery, from which they fire simultaneously or separately during fires, through pipelines the bottom case and nitrogen, carbon dioxide, or some other cheap, non-supporting combustion, after having destroyed the glass caps 2 in the openings of 1 casing X, x with the above-mentioned inductor; through pipelines n and n to lower j and upper covers a, b-carbon dioxide foam; Laurent or, so-called, sleep; - tapped condensed carbonic acid, and through pipelines b and c into the lower and upper covers a, b-water.

All fluids and non-supporting

Combustion gases coming from the fire base into the case a must, however, be let in there under greater pressure than that usually occurs inside the well during a fire due to the strength of you; oil and volatile gases from it.

In the modified device, the covers j and and b are arranged above each other above | the ground level, at what they are separated from: the casing with another cover to, which is above, around the neck | wells, has large holes 6.

Device action Immediately when a fire occurs in a well, it is first blown up from the central fire protection base by the inductor: glass caps 2 in case a, if the latter is below ground level, and allowed from base to both case a and b through a pipeline Lorana, or carbon snow, and the pipeline t is a non-burning gas.

Carbonic acid foam or snow, hitting the cover b and going out through the openings 4 to the outside, cover to the far oastoia I all the ground lying in the burning well I area of land with objects on it and not dote / strong strong heating i ignition leaked from the well nafgi. Part i of foam or snow which, through holes 5, will make its way up into the air, i.e. around the top of the well, | he will embrace the oil flowing from the well of the oil with gases and will not allow j to them oxygen of the outdoor atmosphere. |

As for the unsupportive burning of gas (nitrogen, etc.), carbon dioxide, or snow, they, after hitting through | Pipelines 1 and 4 under pressure in j. hola, due to stronger pressure in this case, will be easily sucked through holes 1 into the well c, and from there along with oil and gases ejected from the earth.

go out into the air, i.e. to the total mass of explosive gases above the well, etc.

The above two main manipulations of carbon dioxide foam or snow and non-supporting gases (nitrogen, etc.) will continue until there are so many non-supporting gases in the burning explosive masses in the air above the well that finally burning oil with explosive gases — the fire will be cut off from the well and fly away to the atmosphere.

The subject matter of the invention.

Claims (2)

1. A device for extinguishing fires in oil wells by pumping liquids and gases into the well that do not support combustion, characterized by by applying metal covers a and b (fig. 1) fixed around a casing XL of a burning fountain, with a series of holes 1 closed against the bottom cover a (fig. 1) in the casing tr}, 3e. The sides of the case with the bell caps, destroyed by noDOxoBoro soaking up with the help of an electric blast 3, in order to pump in the opening in the casing through the case pipe 0-- water, for pumping the same in the upper, equipped with the output GOVERNMENTAL apertures 4 and 5, and Vod foams are pipes and p. 2. The device change according to claim 1, characterized by its use in the upper parts of the casing of three covers: an inner cover with holes 1 and b (Fig. 3), a middle blind cover a and an outer cover b with holes 4 and 5, and serve to inject gas, foam and water into the cover a pipes, p and 6, and pipes to pv are used to inject foam and water into the boot. | qg FIG. four
