摘要
介绍了石油勘探技术中地震勘探的基本原理和当前使用的地震检波器的主要缺陷,设计了一个光纤光栅地震波检波器及探测系统,成功进行了野外实验,与电磁式速度型检波器作了性能对比.发现光纤光栅检波器与油田使用的地震记录仪是兼容的,并在灵敏度和抗干扰能力方面优于传统的速度型检波器.
The basic principle of seismic exploration used in petroleum exploration technology and the main disadvantages of the seismic detector used at present are introduced.A fiber Bragg grating seismic detector and related exploring system are designed and the corresponding field experience is accomplished.Comparisons with the electromagnetic type velocity detector is put forward.The results show that the fiber Bragg grating seismic detector is compatible with the seismic recorder used in oil fields and is superior to the velocity detector in the aspects of sensitivity and anti-jamming ability.
