摘要
澳大利亚煤层气资源丰富,尤其是中煤阶的煤层气具有埋藏深度浅、含气量高、渗透率高等易于商业开发的特点。以澳大利亚H区块中煤阶的煤层气为研究对象,在测井识别煤层的基础上,利用测井、录井、岩心分析等数据开展了煤层气储层分布、煤质、物性以及含气性研究,利用取心分析数据获得的动态兰氏体积构建煤层含气量及含气饱和度模型,实现H区块煤层气储层表征。研究结果表明,澳大利亚H区块煤层气储层具有高含气量、低灰分、低挥发分、低湿度、高固定碳、高渗透率的特点,具有较高开发潜力。煤层气储层特征评价将为后续煤层气开发奠定基础,同时为同类型煤层气储层评价提供借鉴。
Australia is rich in CBM resources,especially middle rank CBM with shallow burial depth,high gas content and high permeability.The medium-rank CBM in Block H of Australia was taken as the research object,and logging,core and other data were taken as the basic data.On the basis of identifying coal by logging data and studying the distribution characteristics,the coal quality,reservoir physical property characteristics and gas content characteristics of CBM reservoir were studied.The dynamic Langmuir volume method was adopted to simulate the coal seam gas content and gas saturation on the basis of core data.The results show that middle rank CBM in H Block of Australia has the characteristics of high gas content,low ash content,low volatile content,low humidity,high fixed carbon and relatively high permeability,which shows a good development prospect.The CBM reservoir characteristics evaluation lays a foundation for the development of Block H in Australia,and provides a reference for the same type of CBM reservoir evaluation in China.
