Abstract

大孔径射孔弹，属于用射弹穿透井壁的装置技术领域。所要解决的技术问题是提供一种射孔孔径大、爆破力强的大孔径射孔弹。解决其技术问题的技术方案，包含外壳、装药层、聚能罩及起爆器安装孔；外壳分为二段，上段为圆锥形体，下段为圆柱形体，内有近似圆锥形的内孔，内孔的下端为开口；紧靠内孔为装药层，装药层装入高爆炸药，在装药层之下为聚能罩；在外壳的圆锥形体的顶端有起爆器安装孔，起爆器装于其中，与起爆电缆连接。本实用新型应用于测井作业中射弹穿透井壁。其有益效果是射弹的孔径大、爆破力强、穿透力强，适用于稠油地层射孔及易产生砂堵的疏松岩层射孔。

Description

大孔径射孔弹
技术领域
本实用新型属于用射弹穿透井壁的装置技术领域。
背景技术
已有技术射孔弹，用于测井中射穿井壁。其不足之处是射孔的孔径较小，一般孔径为10-12毫米，不能满足大孔径射孔的需要。
发明内容
所要解决的技术问题是提供一种射孔孔径大、爆破力强的大孔径射孔弹。
解决其技术问题的技术方案如下：大孔径射孔弹，包含外壳、装药层、聚能罩及起爆器安装孔；外壳分为二段，上段为圆锥形体，下段为圆柱形体，内有近似圆锥形的内孔，内宾孔的下端为开口；紧靠内孔为装药层，装药层装入高爆炸药，在装药层之下为聚能罩；在外壳的圆锥形体的顶端有起爆器安装孔，起爆器装于其中，与起爆电缆连接。
有益效果：本实用新型应用于测井作业中射弹穿透井壁。其有益效果是射弹的孔径大，可以达到20毫米以上，爆破力强、穿透力强，适用于稠油地层射孔及易产生砂堵的疏松岩层射孔。
附图说明
图1为本实用新型的结构图。图1中，1为外壳，2为内孔，3为装药层，4为聚能罩，5为起爆器安装孔，6为开口。
具体实施方案
具体实施方案如下：包含外壳1、装药层3、聚能罩4及起爆器安装孔5；外壳1分为二段，上段为圆锥形体，下段为圆柱形体，内有近似圆锥形的内孔2，内孔2的下端为开口6紧靠内孔2为装药层3，装药层3装入高爆炸药，在装药层3之下为聚能罩4；在外壳的圆锥形体的顶端有起爆器安装孔5，起爆器装于其中，与起爆电缆连接。
