Abstract

本实用新型提供了一种用于油井的夹层枪特种枪弹,它包括一个弹体(1),弹体(1)上具有引爆装置,弹体(1)内具有聚能形炸药腔(2),炸药腔(2)内具有一层炸药层(3),其改进之处在于炸药层(3)的外层面(4)构成炸药腔(2)的外腔面。这种结构的特种枪弹在爆炸时能在不伤及油井套管的情况下炸毁枪体内的弹架和其它零部件,使整个枪体内形成一个通腔。

Description

一种夹层枪特种枪弹
本实用新型涉及一种用于油井的夹层枪特种枪弹。
目前,在公知技术中用于油井的夹层枪位于非射孔井段的枪体内需要一种特种枪弹,这种枪弹在不伤及油井套管的情况下炸毁枪体内的弹架和其零部件,使整个枪体内形成一个通腔,这种特种枪弹国内尚无成形的产品,国外也没有相应的报导。如何设计这种特种枪弹是本行业技术人员急待解决的技术难题。与本实用新型结构较为相近的是夹层枪的射孔弹,它包括一个弹体、弹体上具有引爆装置,弹体内具有聚能形炸药腔,炸药腔内具有一层金属药型罩,在弹体和药型罩之间具有一层炸药层,药型罩的外表面构成炸药腔的外腔面。这种结构的射孔弹仅适合用于油井射孔段的射孔。
本实用新型的目的在于提供一种夹层枪特种枪弹,以克服公知技术之不足。
本实用新型是这样实现的:一种夹层枪特种枪弹,它包括一个弹体(1),弹体(1)上具有引爆装置,弹体(1)内具有聚能形炸药腔(2),炸药腔(2)内具有一层炸药层(3),其特征在于炸药(3)的外层面(4)构成炸药腔(2)的外腔面。
本实用新型提供的夹层枪特种枪弹,由于没有金属药型罩,在枪弹爆炸时能在不伤及油井套管的情况下炸毁枪体内的弹架和其它的零部件,使整个枪体内形成一个通腔。
图1:本实用新型一种结构的主视剖视图。
参照附图结合实施例对本实用新型作进一步说明。
实施例1,附图给出了本实用新型一种具体结构,参阅图1,一种夹层枪特种枪弹,它包括一个弹体(1),弹体(1)上具有引爆装置,弹体(1)内具有聚能形炸药腔(2),炸药腔(2)内具有一层炸药层(3),炸药层(3)的外层面(4)构成炸药腔(2)的外腔面。这种结构特种枪弹,由于没有金属药型罩,在枪弹爆炸时能在不伤及油井套管的情况下炸毁枪体内的弹架和其它零部件,使整个枪体内形成一个通腔。
