【摘要】 二维地震技术贯穿于煤层气勘探开发整个过程。井位部署、开发方案编制、地质分析均离不开二维地震技术所提供的成果。本文通过对沁水盆地煤层气二维地震勘探过程中出现的单炮监视记录远端接收信号弱,目的层反射波不明显、静校正、偏移成像及解释成图四个问题进行了概括,并提出了相应解决对策,在沁水盆地煤层气勘探开发过程中取得了较好的应用效果。更多还原

【Abstract】 The 2D seismic technology is applied to the entire process of the coalbed methane exploration and development.Well deployment,development programming,geological analysis are all needs the results of the 2D seismic technology.This paper summaries the problems which arise in the process of CBM 2D seismic exploration,then proposes the corresponding solutions and achieves a better effect thoughout the process of CBM exploration in QinShui basin.The problems are discussed in the paper such as weak signals,static correction,migration imaging,meanwhile,the reflected wave which belongs to the target layer is not obvious in the monitor records,interpreted as a map and so on.更多还原
