Abstract
The utility model comprises a casing, an ammunition-type cover, an upper end bore, main ammunition, initiating explosive and sealant. The ammunition-type cover is a conical hollow cover with a thin upper part and a thick lower part, and the ammunition-type cover which is pressed into an inner bore of the casing is in a tight fit with the inner bore of the casing. The space between the ammunition-type cover and the inner bore of the casing is filled with the main ammunition and the initiating explosive which are sealed by the sealant. Compared with the prior art, the utility model has the advantages of big explosion force, stronger penetrating force, deeper penetration depth and better oil output effect. In addition, the penetration depth of the utility model can reach more than 1000 mm.
Description
The utility model belongs to drilling technology perforator field.
Perforating bullet is a kind of apparatus commonly used in the drilling technology.In completion formation testing engineering, need perforating bullet lateral well wall emission is got several holes, make oil reservoir fuel-displaced.The perforating bullet of prior art, perforating depth is not enough, influences fuel-displaced effect.
The purpose of this utility model is to provide a kind of perforating depth can reach the above perforating bullet of 1000mm.
The purpose of this utility model is achieved in that a kind of super deep penetrating charge, comprises housing, not uniform thickness cavity liner, main charge, priming and sealing.Housing is a cylinder with upper end for the endoporus of conical cavity, and the tapering of inner chamber upper end is 36 °-38 °: there is upper end hole on the housing top.Cavity liner is a conical hollow cap, and cone wall thickness differs, upper-thin-lower-thick, the inwall tapering of cavity liner is 44.5 °-46.5 °, the outer wall tapering is 46.5 °-47.5 °, and the external diameter of cavity liner is slightly larger than the diameter of housing endoporus, is tight fit when pressing cavity liner in people's housing endoporus.During assembling, paste sealing earlier, pack into successively priming and main charge are pressed into cavity liner again.The back impact force of detonating is strong, and penetration depth is bigger.
The utility model has the advantages that compare with existing perforating bullet, explosive force is big, penetration power is stronger, and penetration depth is bigger, can reach more than the 1000mm, and fuel-displaced effect is better.
Fig. 1 is a structure chart of the present utility model.Fig. 1 is described as follows: 1 is housing, and 2 is cavity liner, and 3 is upper end hole, and 4 is main charge, and 5 is priming, and 6 are sealing.
The utility model is made sampling by the applicant: the long 76mm of this embodiment housing, external diameter 55mm, aperture 43mm, hole depth 69.1mm, 37 ° of hole tapers.The high 49mm of cavity liner, external diameter 43.1mm, 45 ° of inwall taperings, 47 ° of outer wall taperings.When testing at the scene, penetrate the standard concrete target, the degree of depth surpasses 1000mm.
