摘要
为了研究贵州织纳煤田珠藏向斜煤层气井多个含气系统递进排采合排阶段的层间干扰,确定各含气系统间不同层间距对递进排采气、水产能的影响,探讨了珠藏向斜煤层气井递进排采合适的层间距,数值模拟了层间距分别为50、100、150、200、250、300 m的6种方案下的2个含气系统递进排采气、水产能。
In order to study the interlayer interference during the CBM well′s progressive drainage of Zhucang syncline located in Zhina coalfield of Guizhou province, confirm how did the coal seam interval affect on the gas and water capacity of CBM well during progressive drainage as well as discuss the proper coal seam interval of Zhucang syncline, six schemes(the coal seam interval is 50、100、150、200、250、300 m respectively) of gas and water capacity during progressive drainage was done by means of numerical simulation.
