Abstract
A follow-up type composite perforating charge comprises a perforating charge main body consisting of a perforating charge casing, a high-density grain and a metal powder linear. The follow-up type composite perforating charge is characterized in that the lower surface of the perforating charge main body is fixedly provided with a burning material bin consisting of a bin cover, a propulsion powder ring arranged inside the bin cover and a follow-up burning body arranged on the propulsion powder ring. Burning speed and flame sensitivity of the propulsion powder ring are higher than those of the follow-up burning body. Because the burning material bin is filled with burnable materials with two components, when the perforating charge main body ignites perforation by aid of a detonating cord to form a sleeve eye hole and a rock stratum duct, high-temperature and high-pressure actions generated by explosion and jet of the perforating charge leads the burnable propulsion powder ring inside the burning material bin to be burnt, generated thrust force and absorption force generated by jet of the perforation charge lead the follow-up burning body into the rock stratum duct to burn, and generated gas cracks and impacts compaction belts of the duct and then forms micro-cracks on the wall of the duct, thereby realizing the purpose of increasing permeability of the compaction belts.
Description
Technical field
The utility model relates to the improvement of the perforating bullet that uses in oil exploration and the mining operations, is a kind of follow-up formula composite gun perforation bullet specifically.
Background technology
In oil exploration and mining operations, need to use perforating bullet carry out perforating job to the down-hole petroliferous bed, open the eyelet on the sleeve pipe and there is a bigger penetration depth rock stratum, set up the profit passage.But in this process of realization, the perforation jet can produce a compaction band to the rock stratum, has reduced permeability.
The utility model content
The purpose of this utility model is at above-mentioned deficiency, provides a kind of simple in structure, can reduce the compaction of compaction band in perforating job, improves the follow-up formula composite gun perforation bullet of permeability.
The technical scheme that realizes the utility model purpose is:
This follow-up formula composite gun perforation bullet, the perforating bullet main body of being made up of perforating bullet housing, high density powder column and powdered metal liner constitutes, and is characterized in being installed with below the perforating bullet main body incendiary material storehouse.
Described incendiary material storehouse is made up of the follow-up combustible of installing on Cang Gai, the propelling cyclome that is equipped with in the lid of storehouse and the propelling cyclome.
The combustion speed of the combustion speed ratio follow-up combustible of described propelling cyclome is high, advances the flame sensitivity height of the flame sensitivity of cyclome than the follow-up combustible.
This follow-up formula composite gun perforation bullet is that the incendiary material storehouse is installed on the perforating bullet main body, and the combustible material of two kinds of components is housed in the incendiary material storehouse.The perforating bullet main body of forming when perforating bullet housing, high density powder column, powdered metal liner is subjected to the fuse arming test experiment initiation perforation, when forming sleeve pipe eyelet and duct, rock stratum, perforating bullet blast jet and the HTHP effect that is produced, make the flammable propelling cyclome burning in the incendiary material storehouse, the suction that thrust that is produced and perforating bullet jet are produced, the combustible that will follow up is brought in the duct, rock stratum and burning, the gas that is produced carries out pressure break and impact to the compaction band in duct, make cell walls form micro-crack, thereby realize improving the purpose of compaction band permeability.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Among the figure: 1 perforating bullet main body, 2 perforating bullet housings, 3 high density powder columns, 4 powdered metal liners, 5 incendiary material storehouses, 6 Cang Gai, 7 advance cyclome, 8 follow-up combustible.
The specific embodiment
The utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this follow-up formula composite gun perforation bullet, the perforating bullet main body of being made up of perforating bullet housing 2, high density powder column 3 and powdered metal liner 41 constitutes, and is installed with incendiary material storehouse 5 below the perforating bullet main body.The incendiary material storehouse, by storehouse lid 6, the propelling cyclome 7 that is equipped with in the lid of storehouse advances the follow-up combustible 8 of installing on the cyclome to form.Advance the combustion speed height of the combustion speed ratio follow-up combustible of cyclome, advance the flame sensitivity height of the flame sensitivity of cyclome than the follow-up combustible.
The utility model is simple in structure, implements easily.Manufacture the perforating bullet main body that is constituted by perforating bullet housing, high density powder column, powdered metal liner at first routinely; To advance cyclome to be installed in the lid of storehouse, the combustible that will follow up again is fixed on to advance on the cyclome makes the incendiary material storehouse; At last the incendiary material storehouse is installed on the perforating bullet main body.
Claims (3)
