增效复合射孔枪
摘要：
本实用新型涉及一种增效复合射孔枪。主要解决了现有射孔装置需要单独涉及泄压孔，加工效率低、成本高的问题。其主要构造为枪身[8]与枪头[1]、枪尾[11]均用螺纹连接，且分别用“O”型圈[2]密封，在枪身[8]在外壁上设计有轴线截面呈“T”型的特殊盲孔[14]，枪身[8]内安装有弹架[7]，弹架[7]上设计有呈螺旋排列的射孔弹安装孔A[12]、射孔弹安装孔B[13]，弹架[7]与上弹架盘[3]、下弹架盘[10]分别用螺钉[9]连接。本实用新型具有泄压速率快、强身涨径小、枪身结构简单且加工效率高成本低廉等优点。
摘要（英）：

The utility model relates to a synergetic composite perforating gun, which is used for mainly solving the problems that the existing perforating apparatus needing an independent pressure relief hole is low in machining efficiency and high in cost. A main structure of the synergetic composite perforating gun comprises a gun body [8], a gun head[1] and a gun tail[11], which are respectively connected with one another by threads and sealed by utilizing an O-shaped ring [2], a special blind hole [14] with a T-shaped axial cross section is formed in the outer wall of the gun body [8], a gun carrier [7] is installed in the gun body [8], perforating bullet installation holes A [12] and perforating bullet installation holes B [13] are formed on the gun carrier [7] in a screw manner, and the gun carrier [7] is respectively connected with an upper gun carrier disc [3] and a lower gun carrier disc [10] through screws [9]. The synergetic composite perforating gun has advantages of high pressure relief speed, high strength, small expansion diameter, simple structure, high machining efficiency, low cost and the like.
