摘　　要：新疆作为我国西北地区重要的聚煤区,侏罗系煤系地层赋存丰富煤系气资源,3000m以浅的煤系气总量可达25.25×10^(12)m^(3),能够为新疆油气勘探开发开辟新层系;准噶尔盆地南缘-东缘、塔里木盆地北缘的煤层气勘查中均在煤系地层的砂岩、泥(页)岩层段发现良好气测显示,且试采结果表明煤系气开发可大幅提高煤层气井的单井产量;新疆煤系气资源丰富、研究程度低,需要系统开展成藏地质、储层地质、开发机理、适用性开发工程技术等研究评价。Xinjiang region is an important coal accumulation area in northwest China,and the Jurassic strata is the most important occurrence horizon of coal measure gas resources.The total amount of coal measure gas shallow 3000 m can reach 25.25×10^(12)m^(3),which can open up new layers for oil and gas exploration and development in Xinjiang.Through coalbed methane exploration in the southern margin and the eastern margin of Junggar Basin and the northern margin of Tarim Basin,good gas measurements are found in sandstone and mud(shale)strata of coal measure strata,and the test production results show that coal measure gas development can greatly increase the single well production of coalbed methane wells.Since the research degree of these abundant coal measure gas resources is relatively low,it is necessary to systematically carry out research and evaluation on reservoir formation geology,reservoir geology,development mechanism and applicable development engineering technology.
