摘　　要：随着地震勘探技术在沁水盆地的不断深入,从二维到三维,发展到利用CRP(共反射接收点道集)角道集进行煤层气储层预测,使得煤层气储层预测技术方法不断完善。以沁水盆地郑庄示范区为例,三维在精度上明显优于二维,能够较准确地预测煤层的分布范围及厚度情况,但含气性、微裂缝预测精度不理想;而利用CRP角道集数据开展AVO反演、应力场数值模拟及各向异性裂缝检测,效果较显著。预测结果可为该示范区井位部署提供参考依据,为其他地区煤层气地震储层预测提供借鉴。With the deeping of seismic exploration technology in Qinshui Basin,The technology and methods on predicting coalbed gas reservoir is developed from 2Dseismic data to 3Dseismic data,to CMP seismic data.Zhenzhuang Area is taken for example of coalbed gas field in Qinshui Basin.In view of coal distribution and coal seam thickness,The Precision is more better by 3Dseismic data than by 2Dseismic data;in view of coalbed gas,it is no good by CMP seismic data,it mainly uses the methods of the prestack seismic stress field modeling and AVO inversion and anisotropic fracture testing.The good result offeres reliable proof for well location deployment,and the methods sets an example for predicting coalbed gas reservoir in other basins.
