摘要
吉木萨尔凹陷是准噶尔盆地东部面积仅410 km2、石油资源量1.1×108t的一个小凹陷,近期在该区油气勘探获得新的进展,发现吉祥油田。将吉木萨尔凹陷、吐哈盆地、三塘湖盆地的勘探成果进行分析比较后认为,吉祥油田可能是吐哈盆地内吐鲁番油气富集带的向北延伸;吐哈盆地内鄯善油气富集带向北延伸可能会在木垒地区出现;卡拉麦里山边缘煤矿自燃现象,很可能是天然气苗显示的一种特殊表现形态。三塘湖盆地、巴里坤盆地与吐哈盆地同处一个油气富集带上,应引起注意。据此,对该地区的油气勘探提出了新的对策与建议。
Jimusaer sag is relatively small sedimentary sag with an area of 410 km2 and OOIP of 1.1 × 10s t in the eastern part of Junggar ba- sin. 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 ex- tension northward of Turpan oil-gas enrichment belt in Tuha basin; the extension of Shanshan oil-gas enrichment belt northward in this ba- sin will appear possibly in Mulei area of Xinjiang; the spontaneous combustion phenomenon of the coal mine at edge of Kelameili mountain 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 en- richment belt should be paid more attention to. Also, some new countermeasures and suggestions are proposed for future petroleum explora- tion in this area.
