煤层气测井识别与评价方法探讨

Study of Well-Logging Identification and Interpretation of Coalbed Natural Gas

摘要: 本文重点介绍了煤层气测井的综合研究成果。分析了煤层的测井响应特征，确定了煤层厚度的划分方法，利用数学统计的方法，建立了煤储层参数的测井解释模型，提供了包括煤层含气量在内的煤储层参数，进行了煤层力学参数的研究和区域性的综合评价，并为不同勘探开发目的设计了一套适合煤系地层的测井系列方案，最终为煤层气勘探和开发提供可靠的技术支持。

Abstract: This article introduces comprehensive studying results on the well-logging for Coalbed Natural Gas, describes the logging data characteristic of coal, points out the method of coalbed thickness identification with logging data and establishes the model of coal logging data interpretation by mathematic ways which can provides the coalbed parameters including gas saturation. We can study the coal mechanics parameters and give a regional comprehensive evaluation with logging data. And we designed a set of logging series for different aim of Coalbed Natural Gas explora- tion and production. At last, we can give technic support for Coalbed Natural Gas exploration and production.
