摘　　要：依据煤层气储层的特点和CO2的性质,作者通过CO2泡沫压裂液实验研究、压裂工艺探 讨,对CO2泡沫压裂技术在煤层气开发中的应用前景进行了探讨。结果表明,CO2泡沫压裂技术 是一项较为理想的煤层气储层改造技术,但由于其发泡温度(400℃以上)和施工成本等原因,其 应用在地层温度较低和煤层气产量不高的地区会受到一定的限制。According to features of coalbed methane reservior and properties of CO2, the author discusses the prospect of the application of CO2 foam fracturing in the development of coalbed methane by means of making experience research on CO2 foam fracturing fluid and fracturing process discussion. The result shows that the technology of CO2 foam fracturing is a relatively ideal one for the restructuring of the coalbed methane reservoir. However, because of reasons such as the foam temperature (over 40 ℃) and implementation costs, its application in low - temperature seam and or of low output will be constrained.
