Description
用于地下勘探,尤其是油田深井所用的爆破器材。
一般油井的深度不深时,用普通的电雷管即可,油井深度越深其温度越高。如5仟米的井下温度约为200℃,普通雷管就不能使用,必须采用高温电雷管。
根据现有技术资料来看,参阅1979年12月美国杜邦公司,所公开发表的资料,该公司所用E-114雷管,其高温性能是500°F(260℃)温度下,一小时能正常发火,其常规发火电流为1安培。它是一种普通的桥丝式电雷管。它耐高温的时间太短。
本发明是用于油井深井开采石油,其高温性能优于杜邦公司E-114雷管。
本发明产品结构详见附图。
高温电雷管是由套管(1),脚线(2),壳体(3),电极塞(4),桥丝(5),点火药(6),扩爆药(7),炸药(8),底帽(9)组成。
其装药结构及药的成份:第一层装药,即接触桥丝的一端的装药,其成份为改性的苦味酸钾(分子式(NO2)3C6H2OK);第二层装药是扩爆药(7),其成份为改性氮化铅,然后压药,其压药压力为250Kg/Cm2;第三层装药是炸药(8),其成份为改性苦味酸钾,压药压力为475±25Kg/Cm2,并在装药底部扣一金属底帽。所用桥丝为镍铬丝直径为φ0.04毫米,电阻值为1.2~2欧姆。
当在雷管底端插入导爆索,用1安培直流电或220伏交流电通电后,雷管即爆炸,达到引爆导爆索的目的。该雷管的安全电流为400毫安。
实施例:
温度(℃)加热时间(小时) 加热后作发火实验的结果
220 4 正常引爆
240 4 正常引爆
250 4 正常引爆
260 4 正常引爆
270 4 正常引爆
贮存性能:通常贮存5年以上,雷管性能符合要求。
从上述可以看出:美国E-114雷管,在260℃时,只能耐热一小时,而本发明能耐热四小时。
该产品在20000伏充电电容475微微法,串联电阻5000欧对脚-壳放电,产品仍不爆,防静电效果好。所用原材料来源广泛,价格便宜,制造工艺简单。
