摘　　要：中拐凸起是准噶尔盆地西北缘重要的油气勘探区域,下二叠统佳木河组是重要的勘探目的层。中拐凸起南斜坡的拐3井、新光1井、拐201井在佳木河组均有油气显示,试油获得油气流,但出油气点分散,显示油气藏较为复杂。针对佳木河组储集层的复杂性,开展多种地球物理手段进行分析,认为利用传统的阻抗反演无法进行储集层的精细刻画,而利用波形分类技术及含油气检测技术,以在有利沉积相带中寻找甜点区的研究思路,很好地解决了佳木河组储集层横向非均质性强的难点,此研究方法可以推广到其他类似区块,为部署勘探井位提供依据。Zhongguai swell is an important area for petroleum exploration in northwestern margin of Junggar basin, and its Lower Jiamuheformation is the main target zone. Oil and gas shows occurred in Guai-3, Xinguang-1, Guai-201 wells at this formation in southern slope ofZhongguai swell, and also got commercial oil-gas flow up to now. However, the scattering oil-gas yielding points allowed the reservoir to bemore complicated. In view of the complexity of Jiamuhe reservoir, many geophysical methods are used to analyze it. It is suggested that theconventional impedance inversion cannot be applied to fine description of such a reservoir, but waveform division and oil-gas containing de-tection technologies can do it. And the idea of finding＂sweet spot＂areas in the favorable sedimentary facies well solves the difficulty of lat-eral heterogeneity in the reservoir, providing theoretical guidance for the next step of exploration and deployment in this area.
