摘要: 煤层气流态是表征煤层气在介质中流动难易程度的阶段量。综合前人研究经验，借助煤层气流态方程推演解译，对煤层气流态界限进行了划分，总结出煤层气在储层中的流态按渗透率k和运移距离L分布的规律。这为煤层气合理开发方案的制定具有一定的现实意义。

Abstract: The fluid flowing state of coalbed methane is a phase parameter reflecting difficult or easy level for CBM flowing in medium.Based on comprehending the previous experience, and by interpreting and deducing the fluid flowing equation for coalbed methane, the limits of fluid flowing states are divided and the distribution characteristics of fluid flowing state of CBM in reservoir are related with permeability and migration distance is also obtained.It can provide greatly theory supports in drafting reasonable development plans for CBM and has great practical values.
