摘　　要：鸡西盆地南部梨树镇坳陷煤层发育,含气量高,煤层气资源潜力巨大。针对煤层厚度分布变化快,预测难的问题。结合该区现有的情况,本文通过数据分析、子波提取、精细标定和建立模型等工作,应用测井约束反演技术预测了主力含气煤层的分布和厚度,为下步勘探指明了方向。Lishuzhen Depression south of the Jixi Basin has a huge potential of coalbed methane resources because of its coal seam development and high gas content.But the thickness of the coal seam distribution change quickly,and prediction difficult.The paper make use of logging-restrained inversion technique to predict coal seam.The flow of log-constrained seismic inversion includes data analysis,wavelet extraction,detailed calibration and wave impedance model building.The rule of coal seam sickness and distribution in the region was found out.The results provide valuable evidence for further exploration.
