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),铁管(3),其外径为φ6.7mm,内径为φ6.1mm,长为60mm,电极塞(4),材料为玻璃电极塞,直径为φ6.1-0.05mm高,两脚线中心距离为1.65mm。桥丝(5),点火药(6),扩爆药(7)炸药(8),底帽(9),材料可用铁、铝或镁铝合金。其尺寸外径为φ6.1mm,内径为φ5.1mm,高6±0.1mm,底厚0.1~0.15mm组成。
装药结构、装药条件及药的成份:装药工艺为倒装法。首先将焊好桥丝的玻璃电极塞装入管内,然后将管壳装入压药模内,装点火药(6)为改性苦味酸钾:系指加入晶型控制剂糊精其浓度为0.3%,含量不超过1~2%,经过严格的工艺条件而制得的颗粒状苦味酸钾晶体。未经晶型控制剂的苦味酸钾是针状晶体,不利于装药,且耐高温性能也差,以糊精为晶型控制剂制得颗粒状苦味酸钾,其分子式仍为〔C6H2(NO2)3OK〕。其药量150mg,压药压力250kg/cm2;第二层装药(7)装入改性氮化铅:系指经晶型控制剂羧甲基纤维钠其浓度为0.1%,含量不超过0.8~1.0%在反应过程中生成羧甲基纤维铅(胶性物质)以及酒石酸钠其浓度为0.5%、含量不超过0.5%为第二晶型控制剂。经过严格的工艺条件而制得改性氮化铅。该新品种的晶形为球形或椭园形聚合晶体,具有耐高温330℃以上的热性能。其分子式仍是〔Pb(N3)2〕。按此工艺制得的氮化铅具有耐高温不分解的性能,故称改性氮化铅。装药量250mg,再装改性苦味酸钾350mg,压药压力250kg/cm2;第三层装药(8),装改性苦味酸钾,药量450mg,压药压力475±25kg/cm2,并在装药底部扣一金属帽(9),起密封防潮作用。所用桥丝为镍铬丝,直径为φ0.04mm,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 2 正常引爆
贮在性能: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1小时,而本发明能耐2小时。
该产品在20000伏充电电容475微微法,串联电阻5000欧,对脚一壳放电,产品仍不爆,防静电效果良好。所用原材料来源广泛,价格便宜,制造工艺简单。
