-
摘要: 近年来,澳大利亚在煤层气勘探开发中取得了突破性进展。本文根据澳大利亚的研究成果,探讨了原地应力与渗透性和地质构造的关系;详细介绍了运用原地应力测量与数值应力分析预测煤层气高渗透区的方法。Abstract: The breakthrough progress in exploration and development for coalbed methane in Australia is obtained over the past few years.In this paper,according to the research results in Australia,the relationships between in-situ stress and permeability and geologic structure are discussed;the prediction method of high permeability zones of coalbed methane using the in-situ stress measurement and numerical stress analysis is introduced in detail.
