| 摘 要： | 将测井约束反演技术应用于卧龙湖煤矿首采区的地震资料岩性解释过程中。阐述了测井约束反演技术的基本原理,并针对煤田测井数据进行处理与分析;对地震子波进行分析提取,再进行迭代反演运算。通过对煤矿首采区的岩浆岩及煤系进行的综合地质分析,利用测井约束反演技术实现了岩浆岩与煤系的薄层分布信息预测。结果表明,该方法有效地提高了地震数据的分辨率,能解释常规剖面上不易识别的一些地质现象,为采区岩浆岩的分布提供详实的信息。

| Abstract: | The technology of logging constrained inversion was used for lithology prediction and interpretation in the first mining district of Wolonghu coal mine.The theory of logging constrained inversion was expatiated and the logging data was treated and analyzed.The seismic wavelet was analyzed and extracted from the data, and the iterated inversion operations were progressed.Based on the synthetic geological analysis of the first mining district, the distribution information for magmatic rocks and thin layers in coal-bearing series was forecasted.The result indicates that this method can improve the resolution of seismic data effectively and interpret some geological phenomena which can't be recognized in conventional seismic section, and provide reliable information for magmatic rock distribution. |
