煤层气测井评价

方法 在调研的基础上，对各种常规测井定性和定量识别、评价煤层气及效果进行了总结。目的为我国以气的勘探工作提供理论依据。结果 多数常规测井方法识别煤层气效果较好且快速直观；少 常规测井方法能够做到定量解释煤层，但效果不够理想。结论常规测井定性识别煤层的有效方法；若想精确地定量评价煤层气，应引进高精度的成像测井系统和某些特殊测井项目，并考虑引入非线性理论，建立合理的测井解释模型，以便对储层作出精确的评

Evaluation of coalbed gas logging

Method Methods and results for qualitative and quantitative identifcation of various conventional logging and coalbed gas evaluation are summarized after investigation and study. Purpose\ To provied theoretical accordance for future exploration of coalbed gas. Result\ Most conventional logging can identify coalbed gas quickly and visually, but results of the others are not ideal though they can also interpret coalbed gas quantitatively. Conclusion\ Although conventional logging is effective in identifying coalbed gas qualitatively, high precise image logging system and specialized logging must be introduced for the purpose of accurate and quantitative evaluation of coalbed gas. Besides, non lineal theory should also be considered to establish reasonable logging interpretation model so as to evaluate formation up to expected accuracy.
