Abstract

Qinshui Basin possesses enormous deep coalbed methane (CBM) resources. Fine and quantitative description of coal reservoirs is critical for achieving efficient exploration and development of deep CBM. This study proposes a 3D geological modeling workflow that integrates three parts: geological data analysis, 3D geological modeling, and application of the model, which can accurately predict the favorable areas of CBM. Taking the Yushe-Wuxiang Block within the Qinshui Basin as a case study, lithology identification, sequence stratigraphy division, structural interpretation is conducted by integrating well logging, seismic, and drilling data. Six lithology types and regional structural characteristics of the Carboniferous-Permian coal-bearing strata are finely identified. Combining experimental testing on porosity and gas content and well testing on permeability, a 3D geological model that integrates the structural model, facies model, and property model was established. Utilizing this model, the total CBM resource volume in the study area was calculated to be 2481.3 × 108 m3. Furthermore, the model is applied to predict the distribution ranges of four types of CBM favorable areas. The workflow is helpful to optimize well deployment and improve CBM resource evaluation, ultimately provide theoretical guidance for subsequent efficient exploration and development. Our study constitutes a reference case for assessing potential of CBM in other blocks due to the successful integration of multiple available of data and its practical applications.

应用三维地质建模预测煤层气聚集的有利区域:沁水盆地案例研究
沁水盆地拥有巨大的深层煤层气资源。要实现深层煤层气的高效勘探和开发,对煤储层进行精细和定量描述至关重要。本研究提出了集地质资料分析、三维地质建模、模型应用三位一体的三维地质建模工作流程,可准确预测煤层气有利区。以沁水盆地榆社-武乡区块为例,综合测井、地震和钻井资料,进行了岩性识别、层序划分和构造解释。精细识别了石炭纪-二叠纪含煤地层的六种岩性类型和区域构造特征。结合孔隙度和瓦斯含量的实验测试以及渗透率的油井测试,建立了集构造模型、岩相模型和属性模型于一体的三维地质模型。利用该模型,计算出研究区域的煤层气资源总量为 2481.3 × 108 立方米。此外,该模型还用于预测四类煤层气有利区的分布范围。该工作流程有助于优化井位部署,提高煤层气资源评价水平,最终为后续高效勘探开发提供理论指导。我们的研究成功整合了多种可用数据并进行了实际应用,为评估其他区块的煤层气潜力提供了参考案例。
