Abstract

According to outcrop data,the Jurassic source rocks were developed wide in Washixia depression,southeast of Tarim basin,and Ruocan 1 Well was one of the most important exploration wells in this area.By geochemical method,the nature gas origin was analysed and the source rocks in this area were evaluated on base of present data.The content of CH_4 in Well Ruocan 1 was fairly high,belonging to typical dry-gas;and isotope of C_2H_6 indicated its nonmarine origin,sourced from Jurassic coal-bearing rocks.
