摘要
对准噶尔盆地侏罗系煤层宏观和微观特征的研究指出,盆地煤层气资源量十分丰富,但有效勘探深度范围内的资源量相对有限。优选出沙南-沙帐、梧桐窝子地区作为煤层气重点勘探区块,主要目的层系均为侏罗系西山窑组,沙南-沙帐区块目的层可加深到八道湾组。其煤层气成藏条件好,含气性较高,且埋深适中,地下构造和地表条件较简单,适宜进行勘探和开发。
The study of the coalbed macro-and micro-features of Jurassic in Junggar basin shows thai ahhuugh the available resouree quantity of it within depth of exploration is limited, there are abundant coalbed gas resourees in this basin. Shanan-Shazhang and Wutongwozi are selected as the preferable areas for coalbed gas prospecting, with larger zones of Xishanyao formation and even deeper Badaowan formation （in Shanan-Shazhang area）. These areas are in good condition for coalbed gas accumulation and high content of gas. Also, they are suitable for prospecting and development of the gas resource due to the moderate depth and simple subsurface structure and surface condition.
