Abstract: The study of the coalbed macro-and micro-features of Jurassic in Junggar basin shows that although the available resource quantity of it within depth of exploration is limited, there are abundant coalbed gas Resources in this basin. Shanan-Shazhang and Wutongwozi are selected as the preferable areas for coalbed gas prospecting, with target 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.

Key words: Junggar basin, Jurassic, coal bed gas, resource extent, prospecting area
