摘　　要：新疆煤储层普遍具有多煤层的地质特点,因此目前新疆的煤层气开发多采用合层排采技术,但已施工的合采井产气量高低不一。阜康白杨河矿区煤层气勘探程度高,39、41、42三套主力煤层的煤层气资源丰富且易于产出。以阜康白杨河为例,研究了储层压力、渗透率、顶底板岩石特征、临界解吸压力、储层供液能力等对合层排采的影响,分析了合层排采的可行性,以期在新疆后续的煤层气开发中起到借鉴和启示作用。Xinjiang coal reservoirs generally possess the geological characteristics of many coal seams,therefore,the CBM exploitation in Xinjiang is mostly using the technology of multi-layer drainage,but the gas production of some wells is high,some is low.The CBM at Fukang Baiyanghe Mining Area is highly explored,and 39,41,42 CBM resources are abundant and easily to be produced.Taking Fukang Baiyanghe Mining Area as an example,this paper studies reservoir pressure,permeability,the top and floor rock characteristics,critical desorption pressure,reservoir fluid supplying capacity effect on multi-layer drainage,and further analyzes the feasibility of multi-layer drainage with a view to have reference and enlightenment function for the subsequent development of CBM in Xinjiang.
