| 摘 要： | 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、解吸特性,嫁接常规天然气成藏模拟技术,建立了具有独立知识产权的煤层气成藏模拟实验装置,这具有重要的科学意义。系统温度、压力变化对煤层气保存的影响,游离气的扩散、运移、散失,不同水动力对煤层气保存的影响,地层水流动对煤层气的溶失,确立这些影响煤层气保存的主要因素的工作都可以依靠煤层气成藏模拟试验装置得以实现,并最终进行量化分析、级别划分,建立煤层气成藏模式。

| Abstract: | Based on the high-temperature and high-pressure core analysis technique, considering the adsorption and desorption characters of coalbed gas and combined with the pool-forming simulation technique of conventional natural gas, a pool-forming simulation instrument of coalbed gas was set up. By this instrument, the major factors affecting coalbed gas preservation, such as the effects of systematic temperature and pressure changes, the diffusion, migretion and dispersion of free gas, the effects of different hydrodynamics and the dissolution of formation water to coalbed gas, were determined. Through quantitative analyses and grade classification, a pool-forming model of coalbed gas was established. |
