| 中文摘要: |
| 测井综合解释在煤储层研究中意义重大。为深入开展薄互层型低阶煤储层测井综合解释研究，以澳大 利亚 S区块煤储层为研究对象，建立 S区块煤层识别标准，明确煤层纵向分布。通过岩心分析含气量、灰 分与测井数据之间相关性以及测井数据对岩心数据的敏感程度并考虑扩径的影响分别建立不同情况下储层参数解释模型，完成储层参数批量化解释，再应用解释结果实现煤阶的有效划分。应用效果表明测井综合解释结果稳定性强，准确率高，能够为后续煤层气研究提供准确的数据基础，在地质调查工程中为调整煤层气勘探开发力度提供有效信息。 |

| Comprehensive logging interpretation is of great significance in the study of coal reservoir In order to carry out comprehensive logging interpretation on thin-interbedded low-rank coal reservoir,this paper took the coal reservoir in Block S of Australia as research object,has established a coal seam identification standard and clari ed the vertical distribution of coal seams in Block S Based on information got from cores, this paper analyzed the correlation between gas content,ash content and logging data,as well as the sensitivity of logging data against core data,and considered the in uence of expanding diameter,has built the interpretation models of reservoir parameters under different conditions, and completed batch interpretation of reservoir parameters and then applied the interpretation results to realize the e ective division on coal-rank The application results show that the logging comprehensive interpretation results are stable and accurate,which can provide accurate data basis for the follow-up CBM research,and can provide e ective information for adjustment of CBM exploration and development in geological survey engineering |
