鄂尔多斯盆地东缘煤系地层致密气低产原因探究

Study on the causes of low production of tight gas in coal measures in the eastern margin of Ordos Basin

总结了该地区的储层特征,并通过综合气层特征,压缩后效果评估,返排系统和其他数据分析了低产的原因。此外,研究表明:煤层对裂缝构造和天然气产量没有明显影响,为今后致密砂岩气与煤层气合压合采提供了研究依据。

This paper summarizes the reservoir characteristics of the area, and through the comprehensive gas reservoir characteristics,After compression effect evaluation, flowback system and other data analyzed the reasons for low production. In addition, the study shows that coal seam has no obvious influence on fracture structure and natural gas production, It provides a research basis for the combined production of tight sandstone gas and coalbed methane in the future.
