摘要
煤层气作为一种非常规天然气,其运聚机制和成藏模式与常规天然气不同。认为应以高温、高压岩心测试分析技术为基础,充分考虑煤层气的吸附和解吸特性,嫁接常规天然气成藏模拟技术来建立煤层气成藏模拟装置,这也是国家"973"煤层气项目的重要研究内容。煤层气成藏模拟装置能模拟煤层气储层特征,能探索煤层气运聚机制,特别是能探索煤层气藏是如何形成的和煤层气系统是如何被打破的和恢复的,还能模拟地层水流动对煤层气的溶失作用;在诸多单因素模拟的基础上,该装置能开展综合模拟,最终进行量化分析、级别划分和建立煤层气成藏模式。
The mechanism and pattern of reservoir are different between CBM and natural gas. The situation restricted CBM industrialization in China.According to desorption and adsorption character, the 1st CBM reservoir should be set up on the basis of test and analysis in high pressure and temperature environment. It can be simulated the character of CBM reservoir and explored pattern of CBM accumulation and tripping. The problem how CBM reservoir formed broke and recovered will be solved. The comprehensive simulation will be turned into reality and the pattern of CBM reservoir will be set up on the basis of more single factor simulations.
