煤层气勘探开发中地震勘探技术的作用及应用方法探讨

Study on the Effects and Application Methods of Seismic Technique in CBM Exploration and Exploitation

鉴于中国煤层气地质背景的特殊性,指出煤层气勘探开发需要地震勘探技术同时也对其提出了更高的要求。在讨论了目前煤层气地震应用现状的基础上,提出煤层气勘探地震与煤层气开发地震的概念。并结合实例提出了在煤层气勘探评价与开发的不同阶段的地震勘探思路及技术手段。对我国煤层气勘探开发中地震勘探技术的应用具有一定的指导意义。

Whereas the particularity of China＇ s CBM geological setting, the article points out that seismic technique are needed in CBM exploration and exploitation, and it also requires the technique to be better improved. Based on the discussion of CBM seismic technique application situation, the concept of exploration seismic and exploitation seismic was given. In connection with examples, the article also indicates the seismic exploration philosophy and technical measures in the different stages, which has certain guiding significance for China CBM seismic technique application.
