Abstract
一种石油地震勘探震源井炸药保护帽,使投入震源井里的炸药管不浮升至井口,有利于环境的安全。它是在炸药管4的上端螺纹连接保护帽2,保护帽2上有2个以上喇叭口形弹性片1。戴有保护帽2的炸药管4下入震源井里后,保护帽上弹性片可插入裸眼井壁,使炸药管固定于井底。
Description
本实用新型涉及石油地震勘探震源井炸药保护帽。
在石油勘探中,地震勘探是常用的方法,可在大面积上普查。它是通过钻较浅的小直径裸眼井,可称震源井,它一般几米至几十米井深,井下投入炸药管,尔后通电引爆,产生的震波传到地下再返回地面检波器上,通过对检波器上资料的分析,对有油、气显示的地区再通过钻探井录取资料再进一步确定。对上述震源井投炸药后,往往由于天气的变化或其它原因,不能当天引爆,或事隔几天后再引爆。在待引爆过程中,由于井里有水会把炸药管浮升至井口,而且不易被发现,如由于其它原因被引爆,危机人身安全,地表遭到破坏,造成损失;同时也易被地方百姓窃取,其后果也是严重的。
本实用新型的目的在于避免上述目前技术中存在的问题,而提供一种投入震源井的炸药管不能浮升的地震勘探震源井炸药管保护帽。
本实用新型的目的可以通过以下技术方案来达到:在炸药管的上端螺纹连接保护帽,保护帽上有2个以上喇叭口形弹性片。
上述弹性片可为3个。为降低成本,采用塑料保护帽,其上弹性片为一体件。保护帽如似轮船上的锚,弹性片所形成有圆径锥大于震源井的井径,由于具有弹性,随炸药管下入时,可顺井身下入井底。下入井底后由于弹力作用,弹性片可插入裸眼井壁,从而可实现其目的。
本实用新型与上述目前不戴保护帽的炸药管相比较可具有如下优点:下入本震源井的炸药管,由于保护帽上喇叭形弹性片可插入裸眼井壁里,使炸药管固定在井下,在水里不会浮升,可保证震源井深的准确性,也避免了由于浮升至井口可能产生的一切问题,以对投入井下的炸药管不能当时引爆,以后在待引爆时间里安全可靠。
附图1是本实用新型示意图:
附图2是图1上戴上保护帽2的炸药管4投入震源井下状态图。
下面结合附图1将对本实用新型作进一步说明:
由附图1结合附图2所示,在炸药管4的上端螺纹连接保护帽2,保护帽2的外径与炸药管4的外径相同;保护帽2上有2个以上喇叭口弹性片1。
上述保护帽2上可有3个弹性片1,可采用塑料保护帽,成本低,易推广使用。
