【摘要】 静校正技术是煤层气地震数据处理的核心技术。基于沁水盆地煤层气地震资料的特点,本文简析了不同静校正方法的原理,通过对实际资料的深入分析和对静校正方法的反复研究与试用对比,探索得到一套综合利用折射波静校正、初至波剩余静校正和反射波剩余静校正等技术的有效方法,很好地解决了该区煤层气资料的静校正问题,为深化研究该区煤层的地质构造特征以及进行煤储层的裂缝预测和含气性检测奠定了良好基础。更多还原

【Abstract】 The static issue is one of the core techniques in coalbed methane(CBM) seismic data processing.According to the characteristics of coalbed methane seismic data in Qinshui Basin,we simply analyze in this paper the principles of different static methods.Through the analysis and application of actual data,we develop an effective processing sequence including refraction static correction,first break residual static correction and reflected residual static correction to solve the coalbed methane static problem in this area.The processing sequence of coalbed methane seismic data processing laid a good foundation for the geological structure characteristics research,coal reservoir fracture prediction and gas bearing layer detection.更多还原
