摘要
Jimusaer Sag is relatively small sedimentary sag with an area of 410 km2 and OOIP of 1.1×108 t in the eastern part of Junggar Basin.Recently,a new breakthrough for petroleum exploration was the discovery of Jixiang oilfield in it.In this paper,the exploration results from Jimusaer sag,Tuha Basin and Santanghu Basin are analyzed and compared,and then recognized that Jixiang oilfield probably is the extension northward of Turpan oil-gas enrichment belt in Tuha Basin.The extension of Shanshan oil-gas enrichment belt northward in this basin will appear possibly in Mulei area of Xinjiang.The spontaneous combustion phenomenon of the coal mine at edge of Kelameili Mountains is likely to be the special display of natural gas shows.So,Santanghu Basin,Balikun Basin and Hami Basin situated in the same oil-gas enrichment belt should be paid more attention to.
