摘要
采用多、深组合井的激发方式时,由于雷管数量和炮线长度增加使得激发回路的电阻增大,这时使用单台译码器激发会出现组合井起爆不全、译码器不能正确产生验证时断等问题,对遥爆设备的激发能力和激发精度带来影响,直接影响到地震激发效果和所得资料的品质。利用多台译码器激发组合井的施工方法,是解决多井组合爆炸中经常出现爆炸不全、单译码器起爆能力不足的一种新思路,这种方法适用于地表条件为黄土塬、沙漠和半沙漠地带。本文就此进行了探讨,并给出了采用多台译码器同时激发的施工方法,以确保激发能量和数据采集质量。
Using multiple decoders for combination holes shooting is a new way for solving the problems such as incomplete explosive and insufficient ignition capacity with single decoder in the multiple-well and deep-well combination development.Those problems not only affected the firing ability and accuracy of remote device,but also have a direct impact on the seismic data quality.This article discusses those problems in detail and gives the new method of multiple decoder to fire combination holes.This method can be used to ensure the firing energy and data quality and proved to be particularly suitable for exploration in the loess plateau areas,semi-desert and desert areas.
