428XL仪器在微地震采集中的应用
|
摘要
随着地球物理探勘技术的发展,地震勘探仪器应用范围也越来越广泛。在射孔和压裂过程中,应用428XL仪器微地震采集的方法能够降低故障发生率,采集完整的地震资料。值得注意的是如果主机仪器用的是428XL,但地面设备部分或全部使用的是408UL站体,测线数据率必须设置为8Mbit/sec。在施工时,要时刻监视野外排列的情况。当野外排列出现故障时,要记录出现故障的时间以及排列恢复的时间,以便在后期处理时使用。
The development of geophysical prospecting technology brings wider use of seismic prospecting instruments.In the course of perforation and fracture,the application of 428XL instrument may reduce failure rate and gather unbroken seismic data.It is notable that data rate of survey line must be set as 8Mbitc when 428XL is used as a host machine,while 408UL station as the part or the whole of ground facilities.In operation,a lookout should be kept over field arrangement.A record should be made about the time of field arrangement failure and its recovery for the reference in the post process.
