Description
Technical field
The utility model relates to a kind of housing, relates in particular to a kind of perforation shell case.
Background technology
Application number is that 200920094475.6 Chinese patent discloses a kind of Follow-up type composite perforating charge, the perforating bullet main body that is comprised of perforating bullet housing, high density powder column and powdered metal liner consists of, and is installed with the incendiary material storehouse below the perforating bullet main body.Due to the combustible material of two kinds of components being housed in the incendiary material storehouse, when the perforating bullet main body 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 produces, make the flammable propelling cyclome burning in the incendiary material storehouse, the suction that the thrust that produces and perforating bullet jet produce, the combustible that will follow up is brought in the duct, rock stratum and burning, the gas that produces 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.But this perforating bullet uses fuel more, and cost is higher, and can not prevent effectively that chip from staying in the duct of perforating bullet.
Summary of the invention
The utility model be mainly solve the existing perforating bullet cost of prior art higher, can not prevent effectively that chip from staying the medium technical problem in duct of perforating bullet, a kind of perforation shell case is provided, cost is lower, can prevent effectively that chip from staying in the duct of perforating bullet.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises perforation shell case main body, described perforation shell case main body outer wall is provided with conical surface section, described conical surface section is provided with the outer cone face, described outer cone face has two taperings, make two interconnective conical surfaces of the facial formation of outer cone, on the chamber wall of described perforation shell case main body inner chamber, interlocking has inner cover, the chamber wall of described inner cover inner chamber is provided with the inner cone face, described inner cone face has two taperings, makes two interconnective conical surfaces of the facial formation of inner cone of inner cover.The utility model makes the geometry in duct obtain optimization, become a mandarin area change more than 30% times, obtained in actual applications splendid frscturing effect, and under huge blast pressure, produce strong exothermic reaction in several milliseconds of duct formation, the energy that discharges increases near the pressure the duct, generation shoving in the well, with chip from whole duct, comprise from the zone of fracture of non-infiltration and removing, flow channel is optimized and near ideal state, finally realizes the target that cleans the duct, improves flow conductivity.
As preferably, described perforation shell case main body is that the 40CR material is made, and described inner cover is that the Zn prepared material is made.The utility model adopts the bimetal structure of low quenching degree quenching and tempering steel and zinc, makes penetration depth be greatly enhanced.
As preferably, described outer cone face has the conical surface of 120 degree and 60 degree taperings.
As preferably, described inner cone face has the conical surface of 100 degree and 36 degree taperings.The mobile performance in duct is except outside the Pass having with penetration depth, and is also relevant with its geometry, and the facial double tapered design of outer cone and the facial double tapered of inner cone design, and enters flow area after can at utmost increasing perforation.
As preferably, also be provided with vertical tube part on described perforation shell case main body outer wall, be provided with annular groove between described vertical tube part and outer cone face.
As preferably, the chamber wall of described perforation shell case main body inner chamber and the junction surface roughness Ra 6.3-12.5 of inner cover.Can satisfy like this bimetallic in conjunction with fastness, satisfy shell case yield strength demand and prevent that effectively chip from staying in the duct.
As preferably, the thickness of the described conical surface section of described perforation shell case main body is between 0.3-0.5mm.
The beneficial effect that the utility model brings is, the utility model cost is lower, can prevent effectively that chip from staying in the duct of perforating bullet, and perforating depth and output all improve a lot.
