【摘要】 该文研究了地震在煤层气勘探开发中的应用问题,首先利用偏移剖面控制构造特征和煤层的底板形态;再结合钻孔和地震资料确定煤层厚度,在此基础上预测煤储层孔隙度,估算煤层储量,为煤层气勘探开发提供多方位的地质信息。实践表明,地震资料的合理应用,可以确保煤层气开采井的正确布置,降低煤层气开发风险。更多还原

【Abstract】 This paper studied the application of seismic data in coalbed methane exploration and exploitation,firstly,we use migration seismic profile to control the feature of geologic structure and depth of coalbed;secondly, the thickness of coalbed is computed by borehole information and seismic data;and on the basis of above parameters, the porosity of reservoir and the content of CBM is estimated, which can provide many geologic information.The practice indicated that reasonable application of seismic data can decrease the risk of exploitation and ensure the position of the CBM well.更多还原
