Abstract
The invention provides an energetic perforating bullet holder for an oil and gas well, which is used for solving the problems that the traditional perforating bullet holder is easy to loosen and fall off in the underground transportation process and the burst height of a perforating bullet is nonadjustable. The energetic perforating bullet holder comprises a perforating bullet holder, wherein pressing and clamping pieces are symmetrically arranged above the perforating bullet holder; a clamping slot is arranged above the perforating bullet holder and provided with an elastic element; and the perforating bullet holder is internally provided with a boss. The perforating bullet holder is formed by pressing and pouring energetic material through a mould, and the energetic material is formed by mixing a composite explosive and at least one selected from light alloy powder and nonmetal powder. The energetic perforating bullet holder is simple in structure, strong in intercoordination and interconversion adaptability and low in cost; the structure is varied; synergistic perforating explosive cakes can be replaced, and the inside space of a bullet perforator can be saved; and the perforating bullet holder is internally provided with the boss so that the burst height of the perforating bullet can be controlled. The function of a composite explosive cake can be fully replaced, and the energetic perforating bullet holder is suitable for being applied to various perforating processes and perforating bullet types.
Description
Technical field
The invention belongs to perforating oil gas well technical field, particularly a kind of perforating oil gas well can bullet holder with containing.
Background technology
Perforating bullet is most crucial firer's parts of perforating oil gas well well-completing process, in order to make accurately location and the distribution on its carrier of perforation resilience energy, adopt containing can bullet holder be fixed spacing to perforating bullet, not only guarantee that perforating bullet does not loosen, do not come off going into the well in course of conveying, and determine that perforating bullet radial direction on its carrier is vertical, 90 degree of phase places are uniform, and rationally can determine the height of burst and the effective stream aperture of perforating bullet, so bullet holds up vital effect.Therefore, existing perforating bullet holder also exists and easily loosens, easily comes off going into the well in course of conveying, and the height of burst of perforating bullet is non-adjustable.
Summary of the invention
The object of this invention is to provide a kind of perforating oil gas well with containing can bullet holder, with solve existing perforating bullet deposit easily loosen, easily come off going into the well in course of conveying, and the nonadjustable problem of the height of burst of perforating bullet.
The present invention is by the following technical solutions:
A kind of perforating oil gas well is with containing the holder of energy bullet, and comprise perforating bullet holder, be arranged with compression fastener above described perforating bullet holder, described perforating bullet holder Shanghai is provided with draw-in groove, and described draw-in groove is provided with elastic component, is provided with boss in described perforating bullet holder.
Described perforating oil gas well is with containing can bullet holder be cylindrical, truncated cone-shaped or elliposoidal.
To be energetic material form through mould compacting, cast in described perforating bullet holder, and energetic material to be selected from alloy in lightweight powder, non-metal powder at least one and to mix explosive wastewater and mix.
The present invention has the following advantages:
1. structure of the present invention is simple, and interworking exchanges strong adaptability, and cost is low;
2. structure diversification;
3. in perforation mechanism, producing high temperature and high pressure gas, play synergy and pressure break effect to preforation tunnel and radial fissure, instead of synergistic perforating medicine cake, is saving space, perforator inside;
4. be provided with boss in perforating bullet holder, be mainly used to the external assembling perforating bullet in spacing location, the height of burst of perforating bullet can be controlled simultaneously;
The present invention can replace the effect of composite medicine cake completely, is applicable to all kinds of gun perforation process and the application of all kinds of perforating bullet type.
